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 construction services of the Corporation’s vertically-integrated operations (which accounted for 18% of consolidated 2012 net sales), are sold and shipped from a network of 301 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:

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, 2012.

Earnings (Loss) per Common Share

The numerator for basic and diluted earnings (loss) 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 June 30, 2013 and 2012 and the six months ended June 30, 2013, 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. For the six months ended June 30, 2012, all such awards were antidilutive given the net loss available to common shareholders attributable to Martin Marietta Materials Inc.

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

The Corporation’s $100,000,000 secured accounts receivable credit facility (the “AR Credit Facility”) expired by its own terms on April 20, 2013. On April 19, 2013, the Corporation, through a wholly-owned consolidated 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 backed by trade receivables originated by the Corporation ($274,818,000 at June 30, 2013), which the Corporation then sells to the wholly-owned consolidated special purpose subsidiary. Availability under the Trade Receivable Facility is limited to the lesser of the facility limit or 82% of “eligible” receivables, as defined. The Corporation continues to be responsible for the servicing and administration of the receivables purchased. The Corporation has the option to request an increase in 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. At June 30, 2013, outstanding borrowings under the Trade Receivable Facility were classified as long-term on the consolidated balance sheet as the Corporation has the ability and intent to refinance or renew amounts outstanding. The Trade Receivable Facility contains a cross-default provision to the Corporation’s other debt agreements.

Long-Term Debt (continued)

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”), 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 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 the Revolving 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.

The Corporation amended the Credit Agreement Ratio in 2012. The amendment temporarily increased the maximum Ratio to 3.75x at 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 June 30, 2013.

Available borrowings under the Revolving Facility are reduced by any outstanding letters of credit issued by the Corporation under the Revolving Facility. At June 30, 2013, 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 and six months ended June 30, 2013, the Corporation recognized $275,000 and $544,000, respectively, as additional interest expense. For the three and six months ended June 30, 2012, the Corporation recognized $257,000 and $508,000, 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.

Financial Instruments

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

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. 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.

Accounts payable represent amounts owed to suppliers and vendors. The estimated fair value of accounts payable approximates its carrying amounts due to the short-term nature of the payables.

The carrying values and fair values of the Corporation’s long-term debt were $1,093,319,000 and $1,141,592,000, respectively, at June 30, 2013; $1,047,859,000 and $1,105,650,000, respectively, at December 31, 2012; and $1,144,247,000 and $1,204,965,000, respectively, at June 30, 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 using 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.

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:

Six Months Ended
June 30, 2013
(Dollars in Thousands)

Unrecognized tax benefits at beginning of period

$        15,380

Gross increases – tax positions in prior years

4,508

Gross decreases – tax positions in prior years

(2,412)

Gross increases – tax positions in current year

777

Unrecognized tax benefits at end of period

$        18,253

The Corporation anticipates that it is reasonably possible that unrecognized tax benefits may decrease up to $10,290,000 during the twelve months ending June 30, 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 APA with the United States, the impact of which is not included in the table of unrecognized tax benefits at June 30, 2013.

At June 30, 2013, unrecognized tax benefits of $15,035,000 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.

The consolidated overall estimated effective income tax rate for the six months ended June 30, 2012 included a refund of federal tax and interest of $1,626,000 related to the 2006 tax year. This discrete event drove an increase in the consolidated overall estimated effective income tax rate for the six months ended June 30, 2012.

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.

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 a guaranty agreement with Bank of America, N.A., to guarantee a $6,200,000 amortizing loan due April 2015. The Corporation also had 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. 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 on certain of the affiliate’s assets as collateral for potential payments under the agreements.

Second Quarter Ended June 30, 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 construction services, from a network of 301 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 six months ended June 30, 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 and six months ended June 30, 2013 and 2012 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales:

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

Second Quarter Ended June 30, 2013

(Continued)

The Corporation reported higher second-quarter net sales and gross margin (excluding freight and delivery revenues) compared with the prior-year quarter, which was particularly noteworthy in light of excessive rainfall in most of the Corporation’s key markets. Consolidated net sales increased 3.6%, driven by pricing growth in all Aggregates business product lines and a new quarterly net sales record achieved by the Specialty Products business. Net earnings increased 12.4% despite being constrained by the impact of wet weather, particularly in the midwestern and southeastern United States. For example, the state of Iowa had the wettest second quarter in over a century, and, many Georgia markets had rainfall during the quarter more than double the average levels, including Augusta which reported its wettest month in weather history in June. While difficult to isolate all of the quarter’s weather impact, the Corporation knows its effect was at least three-fold. First, with respect to potential lost sales, the Corporation estimates that precipitation reduced shipment volumes between 1.5 million and 1.7 million tons. Second, though more difficult to estimate than the sales component, throughput challenges created by wet weather significantly reduced operational productivity. Finally, lower production volumes led to an underabsorption of fixed costs. Despite these challenging conditions, the Corporation continues to see positive indicators of construction activity, including double-digit growth on a year-to-date basis in the private-sector construction market. Historically, increases in private construction have led to growth in public-sector construction. Management anticipates this trend continuing and the Corporation remains well-positioned to serve these opportunities.

During the quarter, pricing momentum in the aggregates product line continued with each of the Aggregates business’ reportable groups achieving increases. The West Group reported a 2.8% improvement, reflecting price increases implemented over the past year. The Mid-America and Southeast Groups reported average selling price increases of 1.9% and 0.4%, respectively, in the aggregates product line. Recently implemented mid-year pricing increases provide further support for continued pricing momentum. The Corporation’s vertically-integrated businesses also achieved pricing growth, with the ready mixed concrete and asphalt product lines reporting increases of 8.3% and 4.3%, respectively.

Through the first half of the year, growth in construction activity has been concentrated in the private sector which, on a year-to-date basis through May, reported a 12% increase in construction put-in-place. Consistent with this trend, the Corporation’s private-sector markets reported volume growth over the prior-year quarter. The nonresidential market, which represented approximately 30% of second-quarter aggregates shipments, increased 7%. This growth was attributable to commercial construction, namely office and retail, and was partially offset by a decline in shipments to the energy sector due to a modest slowdown in shale oil field activity. The residential construction market continues to recover; housing starts are up more than 10% over the prior year and housing completions are up over 20%. Shipments to the residential market increased 4% and accounted for 13% of second-quarter aggregates shipments, representing a more normalized and balanced percentage of overall product sales. Management expects further increases in residential volumes as the housing market continues to move toward a more sustainable equilibrium. Finally, the ChemRock/Rail end-use market, approximately 10% of second-quarter aggregates shipments, increased 2%.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

Second Quarter Ended June 30, 2013

(Continued)

The infrastructure market comprised the remaining 47% of second-quarter aggregates shipments. Lower government spending and wet weather contributed to an 8% decline in quarterly volumes to this end-use market and a 1.6% overall shipment decline for the Aggregates business. However, given the ongoing recovery of the U.S. economy, reflected by employment growth, management remains optimistic for increased future public-sector construction activity. Similar to the pattern experienced in Texas over the last few years, growth in the residential sector within the Corporation’s geographic areas is expected to stimulate growth in the nonresidential and infrastructure markets to serve an expanding economy and increased population. The Corporation sees early signs of this cycle developing in both Colorado and Georgia.

Management is also encouraged by states’ recent initiatives to address long-neglected infrastructure needs. For example, the South Carolina Department of Transportation recently increased its budget by $500 million for repairs of existing roads and the Indiana Department of Transportation approved up to an additional $415 million annually for construction of new roads and expansion of major highways. Additionally, Texas is expected to initiate work on several large highway projects in the second half of the year in connection with its increased state Department of Transportation budget. Texas is also one of the most proactive states in applications for funding under the Transportation Infrastructure Finance and Innovation Act , or TIFIA, a program with the ability to leverage up to $50 billion in financing for transportation projects of either national or regional significance. A number of TIFIA awards are currently expected to be announced later this year. Consistent with management’s previous viewpoint, given the timing of the initial awards, any meaningful impact of TIFIA is not expected prior to 2014.

The Aggregates business is significantly affected by erratic weather patterns, seasonal changes and other weather-related conditions. Aggregates production and shipment levels 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 significant impact of weather on the Corporation’s operations, second-quarter results are not indicative of expected performance for other interim periods or the full year.

The Specialty Products business continued its strong performance and generated second-quarter net sales of $56.6 million, reflecting growth in both the dolomitic lime and chemicals product lines. Sales of dolomitic lime include the contribution from the Woodville kiln that became operational during the fourth quarter of 2012, partially offset by the impact of a 4% decrease in steel production compared with the prior-year quarter. Earnings from operations of $18.7 million were up 7% over the prior-year quarter, but were negatively affected by higher natural gas costs which reduced earnings from operations by $0.8 million.

Operations personnel continued their focus on cost control, as evidenced by a 20-basis-point expansion of consolidated gross margin (excluding freight and delivery revenues), despite weather constraints that resulted in shipment and production reductions. The Mid-America Group, led by the performance of the Mid-Atlantic Division, which includes Virginia, North Carolina, and South Carolina, achieved a 150-basis-point improvement in gross margin (excluding freight and delivery revenues). The Mid-Atlantic Division leveraged a 10% increase in aggregates product line shipments into an incremental gross margin (excluding freight and delivery revenues) exceeding the Corporation’s publicly-stated expectations.

Quarterly gross profit for the Southeast Group in 2013 was negatively impacted by $1.1 million in unplanned repairs for a shiploader/reclaimer.

Consolidated SG&A expenses were 7.4% of net sales, up 20 basis points compared with the prior-year quarter. On an absolute basis, SG&A increased $2.6 million, largely related to incremental costs for an information systems upgrade expected to be completed by the fall of 2013.

During the second quarter of 2012, the Corporation incurred $9.2 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 second quarter, consolidated other operating income and expenses, net, was income of $0.8 million in 2013 compared with income of $1.7 million in 2012, primarily as a result of higher gains on the sale of assets in 2012.

For the first six months of 2013, consolidated net sales increased 1.4%, driven by pricing and volume improvements for the ready mixed concrete product line and record net sales achieved by the Specialty Products business.

Pricing momentum in the aggregates product line continued with each of our reportable groups achieving pricing growth. The West Group reported a 5.3% improvement, primarily due to price increases implemented over the past year. The Mid-America and Southeast Groups reported average selling price increases of 2.5% and 3.0%, respectively, in the aggregates product line. The Corporation’s vertically-integrated businesses also achieved pricing growth, with the ready mixed concrete and asphalt product lines reporting increases of 8.5% and 4.8%, respectively.

Excessive rainfall and lower government spending contributed to a 4.6% decline in aggregates product line shipments during the six months ended June 30, 2013.

For 2013, Specialty Products’ net sales of $111.8 million increased $9.6 million, or 9.4%, over the prior-year period. 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. Earnings from operations were $35.8 million compared with $35.7 million.

Consolidated gross margin (excluding freight and delivery revenues) was 14.0% for 2013 versus 15.0% for 2012. The reduction reflects lower aggregates product line shipments, which reduced the operating leverage of the Aggregates business. Furthermore, gross profit for the Southeast Group in 2013 was negatively impacted by $1.7 million in unplanned repairs for a shiploader/reclaimer.

During the six months ended June 30, 2012, the Corporation incurred $35.1 million of business development costs related to a proposed significant business combination that was not consummated.

For the first six months, consolidated other operating income and expenses, net, was income of $2.6 million in 2013 compared with income of $1.5 million in 2012, due in part to 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 six months ended June 30 was an expense of $0.1 million in 2013 compared with income of $1.9 million in 2012, with the change resulting from a gain on debt 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 six months ended June 30, 2013 was $48.5 million compared with $27.7 million for the same period in 2012. The improvement is attributable to the absence of significant business development costs incurred 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:

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 $27.7 million for the first six months of 2012.

During the six months ended June 30, 2013, the Corporation invested $50.0 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.

On April 19, 2013, the Corporation, through a wholly-owned consolidated 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 request an increase in 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.

On July 1, 2013, the Corporation acquired three aggregates quarries in Atlanta, Georgia, for $62.0 million.

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 six months ended June 30, 2013 and 2012. Management currently has no intent to repurchase any shares of the Corporation’s common stock. At June 30, 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) 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 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 the Revolving 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 increased the maximum Ratio to 3.75x at June 30, 2013. The Ratio returns to the pre-amendment maximum of 3.50x for the September 30, 2013 calculation date.

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.

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.

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 June 30, 2013, the Corporation had $297 million of unused borrowing capacity under its Revolving Facility, subject to complying with the related leverage covenant. The Trade Receivable Facility expires on April 19, 2014 and the Credit Agreement expires on March 31, 2015.

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 Trade Receivable Facility at June 30, 2013. The Corporation is currently rated by three credit rating agencies; two of those agencies’ credit ratings are investment-grade level and the third agency’s credit rating is 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

Management is encouraged by various positive trends in the Corporation’s business and markets – especially in private-sector employment and construction. Management anticipates volumes to the nonresidential end-use market to increase in the mid-single digits given that the Architecture Billings Index, or ABI, a leading economic indicator for nonresidential construction spending activity, remains at a strong level. 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. By contrast, the weather-related slowdown in aggregates shipments experienced in the first half of the year, coupled with a delay in large infrastructure projects moving through the public letting cycle, leads management to expect aggregates shipments to the infrastructure end-use market to be down in the mid-single digits for the full year. The ChemRock/Rail end-use market is expected to be flat compared with 2012. Cumulatively, management anticipates aggregates product line shipments will increase 1% to 3%.

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

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

Second Quarter Ended June 30, 2013

(Continued)

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.

Aggregates product line direct production costs per ton should be flat compared with 2012. SG&A expenses, excluding costs in 2013 and 2012 related to the information systems upgrade, as a percentage of net sales are expected to decline slightly.

Net sales for the Specialty Products segment are expected to 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 the Moving Ahead for Progress in the 21 st Century Act 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. The Federal sequester that went into effect in March did not appear to have a significant impact on the broader economy in the first half of the year. While transportation investment is mostly exempt from spending cuts, the impact of sequester may become more apparent during the second half of the year. 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; 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 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. 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 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.

(Continued)

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.

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. 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.

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 six months ended June 30, 2013. The residential construction market accounted for approximately 14% of the Corporation’s heritage aggregates product line shipments for the six months ended June 30, 2013.

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 a Trade Receivable Facility. Borrowings under these facilities bear interest at a variable interest rate. A hypothetical 100-basis-point increase in interest rates on borrowings of $440.0 million, which was the collective outstanding balance at June 30, 2013, would increase interest expense by $4.4 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.

For the Quarter Ended June 30, 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 $440.0 million of variable-rate borrowings outstanding at June 30, 2013 would increase interest expense on an annual basis by $4.4 million. Additionally, a 10% change in energy costs would impact annual pretax earnings by $18.8 million.

Item 4.  Controls and Procedures

As of June 30, 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 June 30, 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.
