Organization

Martin Marietta Materials, Inc., (the “Corporation”) is engaged principally in the construction aggregates business. The Corporation’s aggregates product line, which accounted for 71% of consolidated 2012 net sales, includes crushed stone, sand and gravel, and is used primarily for construction of highways and other infrastructure projects, and in the nonresidential and residential construction industries. Aggregates products are also used in the railroad, environmental, utility and agricultural industries. These aggregates products, along with the asphalt products, ready mixed concrete and road paving materials of the Corporation’s vertically-integrated operations (which accounted for 18% of consolidated 2012 net sales), are sold and shipped from a network of 297 quarries, distribution facilities and plants to customers in 33 states, Canada, the Bahamas and the Caribbean Islands.

Effective January 1, 2013, the Corporation reorganized the operations and management reporting structure of its Aggregates business, resulting in a change to its reportable segments. The Corporation currently conducts its aggregates and vertically-integrated operations through three reportable segments as follows:


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

In addition to the Aggregates business, the Corporation has a Specialty Products segment, accounting for 11% of consolidated 2012 net sales, which produces magnesia-based chemicals products used in industrial, agricultural and environmental applications and dolomitic lime sold primarily to customers in the steel industry.

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 the Corporation’s unvested restricted stock awards and incentive stock awards. 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, 2013 and 2012, all such awards were antidilutive given the net loss attributable to Martin Marietta Materials Inc.

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


	Three Months Ended March 31,

2.	Discontinued Operations

Divestitures and Permanent Closures

Operations that are disposed of or permanently shut down represent discontinued operations, and, therefore, the results of their operations through the dates of disposal and any gain or loss on disposals are included in discontinued operations in the consolidated statements of earnings and comprehensive earnings. The results of operations for divestitures do not include Corporate overhead that was allocated during the periods the Corporation owned these operations.

All discontinued operations relate to the Aggregates business. Discontinued operations consist of the following:

Long-term debt	$	1,072,850	$	1,042,183	$	1,127,178

The Corporation’s Credit Agreement, consisting of a $250,000,000 senior unsecured term loan (the “Term Loan Facility”) and a $350,000,000 senior unsecured revolving facility (the “Revolving Facility”), and a $100,000,000 secured accounts receivable credit facility (the “AR Credit Facility”) require 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 for a period of 180 days so long as the Corporation maintains specified ratings on its long-term unsecured debt and the Ratio calculated without such exclusion does not exceed 3.75x. Additionally, if no amounts are outstanding under both the Revolving Facility and the AR Credit Facility, consolidated debt, including debt guaranteed by the Corporation, 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.

4.	Long-Term Debt (continued)

The Corporation amended the Credit Agreement Ratio in 2012. The amendment temporarily increases the maximum Ratio to 3.75x at March 31, 2013 and June 30, 2013. The Ratio returns to the pre-amendment maximum of 3.50x for the September 30, 2013 calculation date. The Corporation was in compliance with this Ratio at March 31, 2013.

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, 2013, December 31, 2012 and March 31, 2012, the Corporation had $2,507,000 of outstanding letters of credit issued under the Revolving Facility.

Accumulated other comprehensive loss includes the unamortized value of terminated forward starting interest rate swap agreements. For the three months ended March 31, 2013 and 2012, the Corporation recognized $269,000 and $251,000, 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 $1,000,000 until the maturity of the 6.6% Senior Notes in 2018.

The Corporation’s AR Credit Facility expired by its own terms on April 20, 2013. On April 19, 2013, the Corporation, through a wholly-owned special purpose subsidiary, established a $150,000,000 trade receivable securitization facility with SunTrust Bank and certain other lenders that may become a party to the facility from time to time (the “Trade Receivable Facility”). Borrowings under the Trade Receivable Facility bear interest at a rate equal to the one-month LIBOR plus 0.6% and are limited based on the balance of the Corporation’s accounts receivable. The Corporation has the option to increase the commitment amount by up to an additional $100,000,000, in increments of no less than $25,000,000, subject to receipt of lender commitments for the increased amount. The Trade Receivable Facility matures on April 19, 2014.

5.	Financial Instruments

The Corporation’s financial instruments include temporary cash investments, accounts receivable, notes receivable, bank overdraft, publicly-registered long-term notes, debentures and other long-term debt.

5.	Financial Instruments (continued)

Temporary cash investments are placed primarily in money market funds, money market demand deposit accounts and Eurodollar time deposits with the following financial institutions: Bank of America, N.A., Branch Banking and Trust Company, JPMorgan Chase Bank, N.A., Regions Bank, Fifth Third Bank, and Wells Fargo Bank, N.A. The Corporation’s cash equivalents have 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.

Customer receivables are due from a large number of customers, primarily in the construction industry, and are dispersed across wide geographic and economic regions. However, customer receivables are more heavily concentrated in certain states (namely, Texas, North Carolina, Iowa, Colorado and Georgia). The estimated fair values of customer receivables approximate their carrying amounts due to the short-term nature of the receivables.

Notes receivable are primarily promissory notes with customers and are not publicly traded. However, using current market interest rates, but excluding adjustments for credit worthiness, if any, management estimates that the fair value of notes receivable approximates the carrying amount.

The bank overdraft represents the float of outstanding checks. The estimated fair value of the bank overdraft approximates its carrying value.

The carrying values and fair values of the Corporation’s long-term debt were $1,078,527,000 and $1,155,051,000, respectively, at March 31, 2013; $1,047,859,000 and $1,105,650,000, respectively, at December 31, 2012; and $1,134,828,000 and $1,129,890,000, respectively, at March 31, 2012. The estimated fair value of the Corporation’s publicly-registered long-term notes was estimated based on level 1 of the fair value hierarchy, quoted market prices. The estimated fair value of other borrowings, which primarily represents variable-rate debt, approximates its carrying amount as the interest rates reset periodically.

6.	Income Taxes


	Three Months Ended March 31,
	2013		2012
Estimated effective income tax rate:
Continuing operations		22.4%		21.0%

Discontinued operations		21.3%		14.6%

(Continued)

6.	Income Taxes (continued)

The Corporation’s 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, the impact of foreign losses for which no tax benefit was realized and the domestic production deduction. The effective income tax rates for discontinued operations reflect the tax effects of individual operations’ transactions and are not indicative of the Corporation’s overall effective income tax rate.

The Corporation’s unrecognized tax benefits, excluding interest, correlative effects and indirect benefits, are as follows:


	Three Months Ended March 31, 2013
		(Dollars in Thousands)
Unrecognized tax benefits at beginning of period		$ 15,380
Gross increases – tax positions in prior years		4,440
Gross decreases – tax positions in prior years		(2,412)
Gross increases – tax positions in current year		389

Unrecognized tax benefits at end of period		$ 17,797

The Corporation anticipates that it is reasonably possible that unrecognized tax benefits may decrease up to $12,146,000 during the twelve months ending March 31, 2014 as a result of resolution through payments to taxing authorities and the expiration of the statute of limitations for the 2009 tax year. The majority of the decrease relates to the expected settlement of the Advance Pricing Agreement (“APA”) the Corporation has with Canada that increased the sales price charged for intercompany shipments from Canada to the United States during the years 2005 through 2011. Upon final settlement with the Canadian taxing authority, the Corporation will be allowed a corresponding refund of tax in the United States for the years 2005 through 2011 pursuant to an expected APA with the United States, which is not included in the table of unrecognized tax benefits at March 31, 2013.

At March 31, 2013, unrecognized tax benefits of $14,708,000 related to permanent income tax differences, net of federal tax expense, would have favorably affected the Corporation’s effective income tax rate if recognized. However, the unrecognized tax benefits, if recognized, would be offset by the corresponding $8,367,000 expense in the United States related to the APA settlement.

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.

Environmental and Governmental Regulations

The United States Environmental Protection Agency (“USEPA”) includes the lime industry as a national enforcement priority under the federal Clean Air Act (“CAA”). As part of the industry wide effort, the USEPA issued Notices of Violation/Findings of Violation (“NOVs”) to the Corporation in 2010 and 2011 regarding the Corporation’s compliance with the CAA New Source Review (“NSR”) program at its Specialty Products dolomitic lime manufacturing plant in Woodville, Ohio. The Corporation has been providing information to the USEPA in response to these NOVs and has had several meetings with the USEPA. The Corporation believes it is in substantial compliance with the NSR program. Because the enforcement proceeding is in its initial stage, at this time the Corporation cannot reasonably estimate what likely penalties or upgrades to equipment might ultimately be required. The Corporation believes that any costs related to any upgrades will be spread over time and will not have a material adverse effect on the Corporation’s operations or its financial condition, but can give no assurance that the ultimate resolution of this matter will not have a material adverse effect on the financial condition or results of operations of the Specialty Products segment of the business.

Guarantee of Affiliate

The Corporation has an unconditional guaranty of payment agreement with Fifth Third Bank (“Fifth Third”) to guarantee the repayment of amounts borrowed by an affiliate under a $24,000,000 revolving line of credit provided by Fifth Third that expires in July 2013 and a guaranty agreement with Bank of America, N.A., to guarantee a $6,200,000 amortizing loan due April 2015. The affiliate has agreed to reimburse and indemnify the Corporation for any payments and expenses the Corporation may incur from these agreements. The Corporation holds a subordinate lien of the affiliate’s assets as collateral for potential payments under the agreements.

9.	Business Segments

The Corporation conducts its aggregates and vertically-integrated operations through three reportable business segments: Mid-America Group, Southeast Group and West Group. The Corporation also has a Specialty Products segment that includes magnesia-based chemicals products and dolomitic lime.

The following tables display selected financial data for continuing operations for the Corporation’s reportable business segments. Corporate loss from operations primarily includes depreciation on capitalized interest, expenses for corporate administrative functions, unallocated corporate expenses and other nonrecurring and/or non-operational adjustments.

RESULTS OF OPERATIONS

First Quarter Ended March 31, 2013

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

OVERVIEW Martin Marietta Materials, Inc. (the “Corporation”), is the nation’s second largest producer of construction aggregates. The Corporation’s annual net sales and earnings are predominately derived from its Aggregates business, which processes and sells granite, limestone, and other aggregates products, including asphalt, ready mixed concrete and road paving materials, from a network of 297 quarries, distribution facilities and plants to customers in 33 states, Canada, the Bahamas and the Caribbean Islands. The Aggregates 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. Aggregates products are also used in the railroad, environmental, utility and agricultural industries.

Effective January 1, 2013, the Corporation reorganized the groups within its Aggregates business. The Corporation currently conducts its aggregates and vertically-integrated operations through three reportable business segments: Mid-America Group, Southeast Group and West Group. The Mid-America Group continues to include operations formerly reported in the Mideast Group, along with operations in Iowa, Minnesota, eastern Nebraska, North Dakota, and Washington (which were formerly reported in the West Group). The Southeast Group remains unchanged. With the exception of operations now reported in the Mid-America Group, there were no other changes to the West Group.

(Continued)

The Corporation also has a Specialty Products 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.

CRITICAL ACCOUNTING POLICIES The Corporation outlined its critical accounting policies in its Annual Report on Form 10-K for the year ended December 31, 2012, filed with the Securities and Exchange Commission (“SEC”) on February 22, 2013. There were no changes to the Corporation’s critical accounting policies during the three months ended March 31, 2013.

RESULTS OF OPERATIONS

Except as indicated, the following comparative analysis in the Results of Operations section of this Management’s Discussion and Analysis of Financial Condition and Results of Operations reflects results from continuing operations and is based on net sales and cost of sales. 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. 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). The following tables present the calculations of gross margin and operating margin for the three months ended March 31, 2013 and 2012 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales:

¹	Net sales by product line reflect the elimination of inter-product line sales.

Due to a more normal winter weather pattern, and in fact, more severe and extended in some parts of the country, aggregates shipments declined 8.8% compared with the prior-year quarter. The prior year benefitted from an unseasonably warm winter, accelerating the start of construction projects in many of the Corporation’s markets into the first quarter. The decline in aggregates volumes directly correlated to the Corporation’s gross profit reduction. Notably, however, the Aggregates business continues to experience pricing growth in each reportable segment and in each product line. This trend bodes well for the future performance of this business as shipments pick up during the remainder of the year. The Specialty Products business benefitted from the new lime kiln completed in the fourth quarter of 2012 and established new records for net sales and gross profit.

From a macroeconomic view, the Corporation sees positive indicators, including upward trends in housing starts, construction employment, and highway obligations. All of these factors should result in increased construction activity during the remainder of the year.

Aggregates product line pricing improved 5.7%. Importantly, pricing growth was widespread as evidenced by increases in nearly all of the geographic markets of the Aggregates business. The West Group achieved the strongest growth, an 8.7% increase, reflecting price increases implemented over the past year and the favorable impact of product and geographic mix. The Mid-America and Southeast Groups reported increases of 4.1% and 5.8%, respectively, in the average selling prices for the aggregates product line.

The improving housing market, an important trend for the economy generally and the aggregates industry specifically, is leading the current economic recovery. Housing starts and completions for the trailing twelve months are up approximately 47% and 36%, respectively, over the comparable period for the prior year. For the quarter, the residential end-use market accounted for 14% of aggregates product line shipments, which is in line with the Corporation’s historical average. Despite the overall reduction in quarterly aggregates shipments, volumes to the residential market increased 1%.

The infrastructure market continues to represent the largest end use for the aggregates product line and comprised 42% of volumes for the quarter. Management is encouraged that highway obligations for fiscal 2013 through March were at the highest level since 2010 and up 28% over the prior-year period. This increase reflects funding stability provided by the Moving Ahead for Progress in the 21^st Century Act, or MAP-21, as well as the Executive Branch’s action last summer which freed up $400 million of unspent earmarks from fiscal years 2003 through 2006. Additionally, February marked the first month in which highway contract awards increased over the prior-year month in almost two years. The Corporation continues to monitor new applications for funding under the Transportation Infrastructure Finance and Innovation Act, or TIFIA. While this program has the ability to leverage up to $50 billion in financing for transportation projects, administrative delays will likely push initial awards to later in 2013 than the U.S. Department of Transportation originally anticipated. Long term, the Corporation anticipates growth in the infrastructure market. While it is not possible to determine any potential impact from the Federal sequester that went into effect in March, it appears that transportation spending is mostly exempt from spending cuts. Still there may be a short-term setback in this end use.

The nonresidential market is the second largest end use and accounted for 33% of aggregates product line shipments for the quarter. While nonresidential volumes were down 8%, the Aggregates business continues to benefit from strong shipments to the energy sector. Finally, the ChemRock/Rail end use was down 12% primarily as a result of weather and a decline in coal traffic on the railroads in the western United States.

The Aggregates business is significantly affected by erratic weather patterns, seasonal changes and other weather-related conditions. Aggregates production and shipment levels coincide 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, first-quarter results are not indicative of expected performance for other interim periods or the full year.

The Specialty Products business continues to make significant contributions to the Corporation’s operating results. Specialty Products set a new record as net sales of $55.2 million increased $3.5 million, or 6.7%, over the prior-year quarter. Sales growth for the dolomitic lime product line reflects shipments from the new lime kiln which became operational in November 2012, partially offset by the loss of higher-margin sales from a customer that filed for bankruptcy. Increased sales, coupled with effective cost control, resulted in record first-quarter gross profit of $19.6 million. Earnings from operations were $17.0 million compared with $18.2 million. Earnings for the prior-year quarter included a $1.2 million favorable litigation settlement.

Consolidated gross margin (excluding freight and delivery revenues) was 3.6% for 2013 versus 6.8% for 2012. The reduction reflects lower aggregates product line shipments, which reduced the operating leverage of the Aggregates business. The following presents a rollforward of the Corporation’s gross profit (dollars in thousands):

Consolidated SG&A expenses were 10.9% of net sales, up 150 basis points compared with the prior-year quarter. On an absolute basis, SG&A increased $4.6 million primarily due to incremental costs related to an information systems upgrade expected to be completed by the fall of 2013.

During the first quarter of 2012, the Corporation incurred $25.9 million of business development costs related to a proposed significant business combination that was not consummated.

Among other items, other operating income and expenses, net, includes gains and losses on the sale of assets; gains and losses related to customer accounts receivable; rental, royalty and services income; accretion expense, depreciation expense and gains and losses related to asset retirement obligations; and research and development costs. For the first quarter, consolidated other operating income and expenses, net, was income of $1.8 million in 2013 compared with an expense of $0.2 million in 2012, primarily as a result of higher gains on the sale of assets in 2013.

In addition to other offsetting amounts, other nonoperating income and expenses, net, are comprised generally of interest income and net equity earnings from nonconsolidated investments. Consolidated other nonoperating income and expenses, net, for the quarter ended March 31 was an expense of $0.6 million in 2013 compared with income of $1.9 million in 2012, with the change resulting from a gain on a bond repurchased at a discount in 2012 and a gain on foreign currency transactions in 2012.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities for the three months ended March 31, 2013 was $18.6 million compared with cash used for operating activities of $4.3 million for the same period in 2012. The improvement is attributable to a reduction in accounts receivable in 2013 and also the impact of business development expenses in 2012. Operating cash flow is primarily derived from consolidated net earnings or loss, before deducting depreciation, depletion and amortization, and offset by working capital requirements. Depreciation, depletion and amortization were as follows:


	Three Months Ended
	March 31,
	2013		2012
	(Dollars in Thousands)
Depreciation	$	40,818	$	42,319
Depletion		959		583
Amortization		1,266		1,496

	$	43,043	$	44,398

The seasonal nature of the construction aggregates business impacts quarterly operating cash flow when compared with the full year. Full year 2012 net cash provided by operating activities was $222.7 million compared with net cash used by operating activities of $4.3 million for the first three months of 2012.

During the three months ended March 31, 2013, the Corporation invested $21.9 million of capital into its business. Full-year capital spending, exclusive of acquisitions, if any, is expected to be approximately $155.0 million in 2013. Comparable full-year capital expenditures were $151.0 million in 2012.

The Corporation can repurchase its common stock through open-market purchases pursuant to authority granted by its Board of Directors. The Corporation did not repurchase any shares of common stock during the three months ended March 31, 2013 and 2012. Management currently has no intent to repurchase any shares of the Corporation’s common stock. At March 31, 2013, 5,042,000 shares of common stock were remaining under the Corporation’s repurchase authorization.

The Credit Agreement (which consists of a $250 million Term Loan Facility and a $350 million Revolving Facility) and the AR Credit Facility require 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 for a period of 180 days so long as the Corporation, as a consequence of such specified acquisition, does not have its ratings on long-term unsecured debt fall below BBB by Standard & Poor’s or Baa2 by Moody’s and the Ratio calculated without such exclusion does not exceed 3.75x. Additionally, if there are no amounts outstanding under both the Revolving Facility and the AR Credit Facility, consolidated debt, including debt guaranteed by the Corporation, will be reduced for purposes of the covenant calculation by the Corporation’s unrestricted cash and cash equivalents in excess of $50 million, such reduction not to exceed $200 million.

The Corporation amended the Credit Agreement Ratio in 2012. The amendment temporarily increases the maximum Ratio to 3.75x at March 31, 2013 and June 30, 2013. The Ratio returns to the pre-amendment maximum of 3.50x for the September 30, 2013 calculation date. Management anticipates the Ratio will stay below the pre-amendment maximum of 3.50x at June 30, 2013.

The Ratio is calculated as debt, including debt guaranteed by the Corporation, divided by consolidated EBITDA, as defined, 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.

Consolidated debt to consolidated EBITDA, as defined, at March 31, 2013 for the trailing twelve months EBITDA		3.22X

In the event of a default on the Ratio, the lenders can terminate the Credit Agreement and AR Credit Facility and declare any outstanding balances as immediately due.

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, are 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, 2013, the Corporation had $237 million of unused borrowing capacity under its Revolving Facility, subject to complying with the related leverage covenant. The Credit Agreement expires on March 31, 2015 and the AR Credit Facility terminated by its own terms on April 20, 2013.

On April 19, 2013, the Corporation, through a wholly-owned special purpose subsidiary, established a $150 million trade receivable securitization facility with SunTrust Bank and certain other lenders that may become a party to the facility from time to time (the “Trade Receivable Facility”). Borrowings under the Trade Receivable Facility are limited based on the balance of the Corporation’s accounts receivable and bear interest at a rate equal to the one-month LIBOR plus 0.6%. The Corporation has the option to increase the commitment amount by up to an additional $100 million in increments of no less than $25 million, subject to receipt of lender commitments for the increased amount. The Trade Receivable Facility matures on April 19, 2014.

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, the Corporation is exposed to the credit markets, through the interest cost related to its variable-rate debt, which includes borrowings under its Revolving Facility, Term Loan Facility and AR Credit Facility at March 31, 2013. The Corporation is currently rated by three credit rating agencies, and while two of those agencies’ credit ratings are investment-grade level, on July 12, 2012, the third agency reduced its rating to one level below investment grade. The Corporation’s composite credit rating remains at investment-grade level, which facilitates obtaining financing at lower rates than noninvestment-grade ratings. While management believes its composite credit ratings will remain at an investment-grade level, no assurance can be given that these ratings will remain at current levels, particularly if any opportunities arise to consummate strategic acquisitions.

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, 2012, filed with the Securities and Exchange Commission on February 22, 2013. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

OUTLOOK

As previously noted, the Corporation expects there to be significantly stronger new construction activity across the country this year, and is well positioned to benefit. Management is encouraged by various positive trends in the Corporation’s business and markets, especially as MAP-21 and other programs are implemented. For the full year, management currently expects shipments to the infrastructure end-use market to increase in the mid-single digits, driven by the impact of MAP-21, TIFIA and state-sponsored programs. Management anticipates the nonresidential end-use market to increase in the high-single digits given that the Architecture Billings Index, or ABI, a leading economic indicator for nonresidential construction spending activity, is reflecting the strongest growth in billings at architecture firms since the end of 2007. Residential construction is experiencing a level of growth not seen since late 2005 with seasonally-adjusted starts ahead of any period since 2008. Management believes this trend in

housing starts will continue and the residential end-use market will experience double-digit volume growth. Finally, management expects the ChemRock/Rail end-use market to be flat compared with 2012. Cumulatively, management anticipates aggregates product line shipments will increase 4% to 6%. As a reminder, the Corporation experienced moderate weather in the first five months of 2012, which allowed an earlier-than-normal start to the construction season in many of its markets. The Corporation experienced a different quarterly pattern of aggregates shipments and earnings in 2012 and comparisons with prior-year periods may continue to be affected in subsequent quarters of 2013.

Management currently expects aggregates product line pricing will increase 2% to 4%. A variety of factors beyond the Corporation’s direct control may continue to exert pressure on volumes and forecasted pricing increase is not expected to be uniform across the company.

Management expects the Corporation’s vertically-integrated businesses to generate between $350 million and $375 million of net sales and $20 million to $22 million of gross profit.

Increased production should lead to a slight reduction in aggregates product line direct production costs per ton compared with 2012. SG&A expenses as a percentage of net sales are expected to decline slightly.

Net sales for the Specialty Products segment should be between $220 million and $230 million, generating $81 million to $85 million of gross profit. Steel utilization and natural gas prices are two key factors for this segment.

Interest expense is expected to remain relatively flat. The Corporation’s effective tax rate is expected to approximate 26%, excluding discrete events. Capital expenditures are forecast at $155 million.

The 2013 outlook includes management’s assessment of the likelihood of certain risk factors that will affect performance. The most significant risk to 2013 performance will be the United States economy and its impact on construction activity. While both MAP-21 and TIFIA credit assistance are excluded from federal budget sequester and the U.S. debt ceiling limit, the ultimate resolution of these issues may have a significant impact on the economy and, consequently, construction activity. Management anticipates the sequester’s impact becoming more apparent during the spring and summer months. Other risks related to the Corporation’s future performance include, but are not limited to, both price and volume and include a recurrence of widespread decline in aggregates volume negatively affecting aggregates price; the termination, capping and/or reduction of the federal and/or state gasoline tax(es) or other revenue related to infrastructure construction; a significant change in the funding patterns for traditional federal, state and/or local infrastructure projects; a reduction in defense spending, and the subsequent impact on construction activity on or near military bases, particularly if sequestration of budget programs occurs; a decline in nonresidential construction, a decline in energy-related drilling activity resulting from certain regulatory or economic factors, a slowdown in the residential construction recovery, or some

combination thereof; and a continued reduction in ChemRock/Rail shipments resulting from declining coal traffic on the railroads. Further, increased highway construction funding pressures resulting from either federal or state issues can affect profitability. Currently, nearly all states have general fund budget issues driven by lower tax revenues. If these negatively affect transportation budgets more than in the past, construction spending could be reduced. North Carolina, a state that disproportionately affects the Corporation’s revenue and profitability, is among the states experiencing these fiscal pressures, although recent statistics indicate that transportation budgets and tax revenues are increasing. The Specialty Products business essentially runs at capacity; therefore any unplanned changes in costs or realignment of customers introduce volatility to the earnings of this segment.

The Corporation’s principal business serves customers in aggregates-related construction markets. This concentration could increase the risk of potential losses on customer receivables; however, payment bonds normally posted on public projects, together with lien rights on private projects, help to mitigate the risk of uncollectible receivables. The level of aggregates demand in the Corporation’s end-use markets, production levels and the management of production costs will affect the operating leverage of the Aggregates business and, therefore, profitability. Production costs in the Aggregates business are also sensitive to energy and raw materials prices, both directly and indirectly. Diesel fuel and other consumables change production costs directly through consumption or indirectly by increased energy-related input costs, such as, steel, explosives, tires and conveyor belts. Fluctuating diesel fuel pricing also affects transportation costs, primarily through fuel surcharges in the Corporation’s long-haul distribution network. The Specialty Products business is sensitive to changes in domestic steel capacity utilization and the absolute price and fluctuations in the cost of natural gas. However, due to recent technology developments allowing the harvesting of abundant natural gas supplies in the U.S., natural gas prices have stabilized.

Transportation in the Corporation’s long-haul network, particularly rail cars and locomotive power to move trains, affects its ability to efficiently transport material into certain markets, most notably Texas, Florida and the Gulf Coast. The availability of trucks and drivers to transport the Corporation’s product, particularly in markets experiencing increased demand due to energy sector activity, is also a risk. The Aggregates business is also subject to weather-related risks that can significantly affect production schedules and profitability. The first and fourth quarters are most adversely affected by winter weather, and the operations in the Denver, Colorado, market increase the Corporation’s exposure to winter weather. Hurricane activity in the Atlantic Ocean and Gulf Coast generally is most active during the third and fourth quarters.

Risks to the full-year outlook include shipment declines as a result of economic events beyond the Corporation’s control. In addition to the impact on nonresidential and residential construction, the Corporation is exposed to risk in its estimated outlook from credit markets and the availability of and interest cost related to its debt.

The Corporation’s future performance is also exposed to risk from tax reform at the federal and state levels.

OTHER MATTERS If you are interested in Martin Marietta Materials, Inc. stock, management recommends that, at a minimum, you read the Corporation’s current Annual Report and Forms 10-K, 10-Q and 8-K reports to the SEC over the past year. The Corporation’s recent proxy statement for the annual meeting of shareholders also contains important information. These and other materials that have been filed with the SEC are accessible through the Corporation’s website at www.martinmarietta.com and are also available at the SEC’s website at www.sec.gov. You may also write or call the Corporation’s Corporate Secretary, who will provide copies of such reports.

Investors are cautioned that all statements in this Quarterly Report that relate to the future involve risks and uncertainties, and are based on assumptions that the Corporation believes in good faith are reasonable but which may be materially different from actual results. Forward-looking statements give the investor the Corporation’s expectations or forecasts of future events. You can identify these statements by the fact that they do not relate only to historical or current facts. They may use words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” and other words of similar meaning in connection with future events or future operating or financial performance. Any or all of the Corporation’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 Quarterly Report on Form 10-Q include, but are not limited to, the performance of the United States economy and the resolution of the debt ceiling and sequestration issues; widespread decline in aggregates pricing; the discontinuance of the federal gasoline tax or other revenue related to infrastructure construction; the level and timing of federal and state transportation funding, including federal stimulus projects and most particularly in Texas, one of the Corporation’s largest and most profitable states, and North Carolina, Iowa, Colorado and Georgia, which when coupled with Texas, represented 57% of 2012 net sales of the Aggregates business; 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 decline in defense spending, and the subsequent impact on construction activity on or near military bases, particularly if sequestration of budget programs occurs; a decline in the commercial component of the nonresidential construction market, notably office and retail space; a slowdown in residential construction recovery; 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, conveyor belts, and with respect to the Specialty Products segment, natural gas; continued increases in the cost of other repair and supply parts; transportation availability, notably the availability of railcars and locomotive power to move trains to supply the Corporation’s Texas, Florida 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 and cost of

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 nonresidential and residential construction markets, could decline if companies and consumers are unable to obtain financing for construction projects or if economic uncertainty causes delays or cancellations to capital projects. Additionally, declining tax revenues and state budget deficits have negatively affected states’ abilities to finance infrastructure construction projects.

Demand in the residential construction market is affected by interest rates. The Federal Reserve kept the federal funds rate near zero percent during the quarter ended March 31, 2013. The residential construction market accounted for approximately 8% of the Corporation’s heritage aggregates product line shipments in 2012.

Aside from these inherent risks from within its operations, the Corporation’s earnings are affected also by changes in short-term interest rates as a result of any temporary cash investments, including money market funds and Eurodollar time deposit accounts; any outstanding variable-rate borrowing facilities; and defined benefit pension plans. Additionally, the Corporation’s earnings are affected by energy costs. The Corporation has no material counterparty risk or foreign currency risk.

Variable-Rate Borrowing Facilities. The Corporation has a $600 million Credit Agreement, comprised of a $350 million Revolving Facility and $250 million Term Loan Facility, and an AR Credit Facility. Borrowings under these facilities bear interest at a variable interest rate. A hypothetical 100-basis-point increase in interest rates on borrowings of $425.6 million, which was the collective outstanding balance at March 31, 2013, would increase interest expense by $4.3 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, 2012, filed with the Securities and Exchange Commission on February 22, 2013.

Page 42 of 47

MARTIN MARIETTA MATERIALS, INC. AND CONSOLIDATED SUBSIDIARIES

FORM 10-Q

For the Quarter Ended March 31, 2013

Energy Costs. Energy costs, including diesel fuel and natural gas, represent significant production costs for the Corporation. The Corporation’s Specialty Products business has fixed price agreements for the supply of coal and approximately 25% of its natural gas needs in 2013. A hypothetical 10% change in the Corporation’s energy prices in 2013 as compared with 2012, assuming constant volumes, would impact annual 2013 pretax earnings by approximately $18.8 million.

Aggregate Risk for Interest Rates and Energy Costs. Pension expense for 2013 is calculated based on assumptions selected at December 31, 2012. Therefore, interest rate risk in 2013 is limited to the potential effect related to the Corporation’s borrowings under variable-rate facilities. The effect of a hypothetical increase in interest rates of 1% on $425.6 million of variable-rate borrowings outstanding at March 31, 2013 would increase interest expense on an annual basis by $4.3 million. Additionally, a 10% change in energy costs would impact annual pretax earnings by $18.8 million.

Item 4. Controls and Procedures

As of March 31, 2013, 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, 2013. 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.

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 March 31, 2013:

•

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 a “S&S” violation). MSHA inspectors will classify each citation or order written as a “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 March 31, 2013, 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.
