    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. 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. The diluted per-share computations reflect a change in the number of common shares outstanding (the denominator) to include the number of additional shares that would have been outstanding if the potentially dilutive common shares had been issued.

5.   Long-Term Debt (continued)
 
    The Corporation’s $325,000,000 five-year revolving credit agreement, $130,000,000 unsecured term loan (the “Term Loan”) and $100,000,000 three-year secured accounts receivable credit facility (the “AR Credit Facility”) are subject to a leverage ratio covenant. The covenant 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 months (the “Ratio”) to not exceed 3.50 to 1.00 as of the end of any fiscal quarter. Furthermore, the covenant allows the Corporation to exclude debt incurred in connection with acquisitions from the Ratio 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 the maximum Ratio plus 0.25. Certain other nonrecurring items and noncash items, if they occur, can also be excluded from the Ratio. The Corporation was in compliance with the Ratio at June 30, 2010.
 
    The Corporation unwound two forward starting interest rate swap agreements with a total notional amount of $150,000,000 (the “Swap Agreements”) in April 2008. The Corporation made a cash payment of $11,139,000, which represented the fair value of the Swap Agreements on the date of termination. The accumulated other comprehensive loss, net of tax, at the date of termination is being recognized in earnings over the life of the 6.6% Senior Notes. For the three and six months ended June 30, 2010, the Corporation recognized $223,000 and $441,000, respectively, as additional interest expense. For the three and six months ended June 30, 2009, the Corporation recognized $208,000 and $411,000, respectively, as additional interest expense. The ongoing amortization of the terminated value of the Swap Agreements will increase annual interest expense by approximately $1,000,000 until the maturity of the 6.6% Senior Notes in 2018. The accumulated other comprehensive loss related to the Swap Agreements was $5,621,000, net of cumulative noncurrent deferred tax assets of $3,677,000, at June 30, 2010; $5,887,000, net of cumulative noncurrent deferred tax assets of $3,852,000, at December 31, 2009; and $6,145,000, net of cumulative noncurrent deferred tax assets of $4,020,000, at June 30, 2009.
 
6.   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.
 
    Temporary cash investments are placed primarily in money market funds and Eurodollar time deposits with the following financial institutions: Bank of America, N.A., Branch Banking and Trust Company, JP Morgan Chase Bank, N.A. 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.

6.   Financial Instruments (continued)
 
    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, Georgia, Iowa and Louisiana which accounted for approximately 56% of the Aggregate business’ 2009 net sales). The estimated fair values of customer receivables approximate their carrying amounts.
 
    Notes receivable are primarily related to divestitures 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 estimated fair value of the Corporation’s publicly registered long-term notes and debentures at June 30, 2010 was $962,610,000, compared with a carrying amount of $912,555,000 on the consolidated balance sheet. The fair value of this long-term debt was estimated based on quoted market prices. The estimated fair value of other borrowings, including the Corporation’s Term Loan and AR Credit Facility, was $143,530,000 at June 30, 2010 and approximates its carrying amount.
 
    The carrying values and fair values of the Corporation’s financial instruments are as follows (dollars in thousands):
                                                 
    June 30, 2010   December 31, 2009   June 30, 2009

7.   Income Taxes
 
    Income tax expense reported in the Corporation’s consolidated statements of earnings includes income tax expense on earnings attributable to both the Corporation and its noncontrolling interests.
                 
    Six Months Ended
June 30,
    2010   2009
Estimated effective income tax rate:
               
Continuing operations
    29.5 %     28.4 %
 
               
Discontinued operations
    28.0 %     30.2 %
 
               
Consolidated Overall
    29.4 %     28.4 %
 
               
    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 depletion allowances for mineral reserves 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.
 
    On March 23, 2010, the Patient Protection and Affordable Care Act (PPACA) was signed into law. Among other things, the PPACA reduces the tax benefits available to an employer that receives the Medicare Part D subsidy. Employers that receive the Medicare Part D subsidy recognize the deferred tax effects of the reduced deductibility of the postretirement prescription drug coverage in continuing operations in the period of enactment. The effects of changes in tax law are recognized as discrete events in the period of enactment. Accordingly, the overall estimated effective income tax rate for the six months ended June 30, 2010 includes the effect to the Corporation of the PPACA.
 
    The change in the year-to-date consolidated overall estimated effective income tax rate during the second quarter of 2010, when compared with the year-to-date consolidated overall estimated effective tax rate as of March 31, 2010, decreased consolidated net earnings for the six months ended June 30, 2010 by $5,436,000, or $0.12 per diluted share.
 
    The change in the year-to-date consolidated overall estimated effective income tax rate during the second quarter of 2009, when compared with the year-to-date consolidated overall estimated effective tax rate as of March 31, 2009, decreased consolidated net earnings for the six months ended June 30, 2009 by $1,482,000, or $0.03 per diluted share.

  7.   Income Taxes (continued)
 
      The following table summarizes changes in the Corporation’s unrecognized tax benefits, excluding interest and correlative effects, for the six months ended June 30, 2010 (dollars in thousands):
         
Unrecognized tax benefits at beginning of period
  $ 16,722  
Gross increases — tax positions in prior years
    18,128  
Gross decreases — tax positions in prior years
    (1,910 )
Gross increases — tax positions in current year
    781  
 
     
Unrecognized tax benefits at end of period
  $ 33,721  
 
     
    At June 30, 2010, unrecognized tax benefits of $10,167,000, net of federal tax benefits and related to interest accruals and permanent income tax differences, would have favorably affected the Corporation’s effective tax rate if recognized.
 
    In July 2010, the Corporation effectively settled issues related to the 2004 and 2005 tax years and also settled the Internal Revenue Service audit for the 2007 tax year. These settlements increased unrecognized tax benefits by $680,000. The Corporation anticipates that it is reasonably possible that $10,762,000 of unrecognized tax benefits may change during the twelve months ending June 30, 2011 due to the expiration of the statute of limitations for federal examination of the 2006 tax year.

Total net periodic benefit cost
  $ 11,999     $ 16,106     $ 905     $ 994  
 
                       
9.   Contingencies
 
    The Corporation is engaged in certain legal and administrative proceedings incidental to its normal business activities. During the three months ended June 30, 2010, the Corporation settled legal proceedings relating to its Greenwood, Missouri, operation for approximately $7,000,000. In connection with the settlement, the Corporation reversed the excess of the established legal reserve, thereby increasing net earnings by $2,751,000, or $0.06 per diluted share.
 
    In the opinion of management and counsel, it is unlikely that the outcome of any other 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 results of the Corporation’s operations, its cash flows or its financial position.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
Second Quarter Ended June 30, 2010
Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
OVERVIEW Martin Marietta Materials, Inc. (the “Corporation”), conducts its operations through four reportable business segments: Mideast Group, Southeast Group, West Group (collectively, the “Aggregates business”) and Specialty Products. 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 from a network of 286 quarries, distribution facilities and plants to customers in 31 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 commercial and residential building development. The Specialty Products segment 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, 2009, filed with the Securities and Exchange Commission on February 26, 2010. There were no changes to the Corporation’s critical accounting policies during the six months ended June 30, 2010.
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. The Corporation’s heritage aggregates product line excludes volume and pricing data for acquisitions that have not been included in prior-year operations for the comparable period and divestitures.
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, 2010 and 2009 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales (dollars in thousands):

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
Second Quarter Ended June 30, 2010
(Continued)
The Corporation showed significant improvement despite the continuing challenging economic environment. Of particular note is the performance of the Corporation’s heritage aggregates volume which increased 8.6%, making this the first quarter in four years with growth in heritage aggregates shipments. Overall, however, the most encouraging sign is that this volume growth was widespread — across each of the Corporation’s end-use markets and geographic segments.
As an end use, infrastructure continues to represent over 55% of the Corporation’s Aggregates business and, as such, played a significant role in the Corporation’s second quarter results. During the second quarter of 2010, the Aggregates business experienced an 11% increase in aggregates volume in the infrastructure market over the comparable second quarter of 2009. As expected, many of the Corporation’s key states began spending funds from the American Recovery and Reinvestment Act (“ARRA” or “Stimulus”) in earnest during the quarter and aggregates volumes consumed on Stimulus projects increased 200% compared with the prior-year quarter. Even more notably, the infrastructure end use market, excluding shipments to Stimulus-funded projects, had volume growth of 6% due to state spending on delayed road maintenance projects. Further, volume growth of 10% in the Corporation’s nonresidential end-use market was driven by an increase in oilfield activity, as aggregates are essential to build oilfield roads and drilling pads. The nonresidential construction market, excluding shipments to the oilfield industry, had volume growth of 3.5%, partially as a result of contractors and project owners taking advantage of historically low construction prices. Residential and ChemRock/Rail had volume increases of 8% and 6%, respectively.
The Mideast Group and West Group each generated double-digit volume increases — nearly 11% and 10%, respectively, in heritage aggregates product line shipments. Growth in the Mideast Group was fueled by Stimulus-funded jobs, as 40% of its increased volume was attributable to shipments to these projects. More specifically, the Corporation’s Indiana markets benefited significantly from this volume growth, reporting a 45% increase in heritage aggregates shipments for the second quarter 2010. The West Group benefited from both Stimulus-funded projects and the increased shipments to the oilfield industry.
Overall heritage aggregates product line pricing decreased 3.8% compared with the prior-year quarter. Consistent with recent trends, pricing varied significantly by market and ranged from an increase of 12% to a decrease of 14%. Competitive forces remain a challenge, particularly in markets that enjoyed strong residential and nonresidential construction activity during the previous economic cycle. These markets now often have an over-supply of contractors who have tended to bid aggressively on Stimulus-related projects, thereby reducing the competitiveness of the Corporation’s long-term customers. Management expects this pressure will ease as residential and nonresidential construction markets continue to either recover or reach levels of sustained stability. In addition to the competitive pressures, geographic mix is also an important factor relative to overall aggregates pricing. The Corporation’s top markets, in terms of volume recovery, for the second quarter 2010 — Indiana, Arkansas and North Texas — each have average selling prices less than the overall average for the Aggregates business.

Still, the incremental operating margin achieved in these markets underscores management’s view that volume recovery, combined with the Corporation’s lean operating cost structure, will lead to record incremental margins even as the Corporation experiences pricing pressures. For example, the Mideast Group reported an incremental operating margin of 78% for the second quarter of 2010, driven in large part by the volume recovery in the Indiana markets. Management expects this type of performance to repeat in multiple markets across the Corporation as volume rebounds.
The following tables present volume and pricing data and shipments data for the aggregates product line. Heritage aggregates operations exclude volume and pricing data for acquisitions that were not included in prior-year operations for the comparable period and divestitures.

RESULTS OF OPERATIONS
Second Quarter Ended June 30, 2010
(Continued)
The Aggregates business is significantly affected by 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 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. Because of the potentially 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 once again achieved record performance and contributed significantly to the Corporation’s second-quarter results. This business expanded its net sales by $14.6 million, or 44%, compared with the prior-year quarter and its operating margin (excluding freight and delivery revenues) by 1,160 basis points to 35.1% for the quarter. Specialty Products had volume growth in all major product lines and continued its focus on cost control programs. Earnings from operations of $16.8 million increased $9.0 million when compared with the prior-year quarter and surpassed the record for earnings from operations established in the first quarter of 2010.
The Corporation’s strong results continue to reflect its ability to control operating costs and the Corporation’s operating team also remains focused on safety, productivity and customer service. Direct production costs in the Aggregates business increased $14.6 million, or 6.6%, driven in large part by $5.8 million of increased energy costs.
The Corporation’s gross margin excluding freight and delivery revenues for the three months ended June 30 decreased 60 basis points to 26.6% in 2010.
The following presents a rollforward of the Corporation’s gross profit (dollars in thousands):

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
Second Quarter Ended June 30, 2010
(Continued)
Selling, general and administrative expenses declined $3.2 million for the quarter compared with the 2009 second quarter due to lower personnel costs related to stock-based compensation. The Corporation’s objective is to hold selling, general and administrative expenses flat with 2009, excluding required payments under certain retirement plans which will occur in the second half of the year.
Among other items, other operating income and expenses, net, includes gains and losses on the sale of assets; gains and losses related to accounts receivable; rental, royalty and services income; and the accretion and depreciation expenses related to asset retirement obligations. For the second quarter, consolidated other operating income and expenses, net, was income of $6.5 million in 2010 compared with an expense of $1.8 million in 2009. During the second quarter of 2010, the Corporation settled legal proceedings relating to its Greenwood, Missouri, operation for less than its established legal reserve, thereby increasing other operating income for the West Group by $5.0 million. Second quarter 2009 included $1.7 million of transaction costs and a $1.2 million property loss.
Interest expense was $16.8 million for the second quarter 2010 as compared with $18.7 million for the prior-year quarter. The decrease primarily resulted from lower outstanding borrowings during the three months ended June 30, 2010 as compared with the prior-year quarter.
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 June 30, was expense of $1.3 million in 2010 compared with income of $1.3 million in 2009, primarily as a result of lower earnings from nonconsolidated equity investments and a loss on foreign currency transactions in 2010.
Six Months Ended June 30
Notable items for the six months ended June 30, 2010 included:
  Net sales of $738.3 million, down 0.3% compared with prior-year period
 
  Heritage aggregates product line volume down 0.3% and pricing down 3.6% compared with the prior-year period
 
  Selling, general and administrative expenses down $6.8 million compared with the prior-year period
 
  Consolidated operating margin (excluding freight and delivery revenues) of 10.5% compared with 11.3% for the prior-year period
 
  Earnings per diluted share of $0.65, compared with $0.75 for the prior-year period

Specialty Products’ net sales were $89.6 million for the first six months of 2010 compared with $66.4 million for the prior-year period. The increase in net sales is due to volume growth in all major product lines.

Selling, general and administrative expenses declined $6.8 million during the six months ended June 30, 2010 due to lower personnel costs. The Corporation’s objective is to hold selling, general and administrative expenses flat with 2009, excluding required payments under certain retirement plans.
For the six months ended June 30, consolidated other operating income and expenses, net, was income of $7.6 million in 2010 compared with an expense of $2.1 million in 2009. In addition to higher gains on asset sales, during 2010, the Corporation settled legal proceedings relating to its Greenwood, Missouri, operation for less than its established legal reserve, thereby increasing other operating income for the West Group by $5.0 million. The results for the six months ended June 30, 2009 included $1.8 million of transaction costs and a $1.2 million property loss.
Consolidated interest expense was $34.4 million for the six months ended June 30, 2010 as compared with $37.2 million for the prior-year period. The decrease primarily resulted from lower outstanding borrowings during 2010.
The change in the year-to-date consolidated overall estimated effective income tax rate during the second quarter of 2010, when compared with the year-to-date consolidated overall estimated effective tax rate as of March 31, 2010, decreased consolidated net earnings for the six months ended June 30, 2010 by $5.4 million, or $0.12 per diluted share. In addition, the 2010 overall effective tax rate includes the reduction of tax benefits for the Medicare Part D subsidy resulting from the enactment of the Patient Protection and Affordable Care Act (PPACA). Management expects the overall effective tax rate for the full year, inclusive of the effects of PPACA, to be approximately 28%.
LIQUIDITY AND CAPITAL RESOURCES Net cash provided by operating activities during the six months ended June 30, 2010 was $86.3 million compared with $116.7 million in the comparable period of 2009. Operating cash flow is primarily from consolidated net earnings, before deducting depreciation, depletion and amortization, offset by working capital requirements. Net cash provided by operating activities for the first six months of 2010 as compared with the year-earlier period reflects a $94.9 million build in accounts receivable for the six months ended June 30, 2010 resulting from increased sales occurring in the second quarter of the current year. Management expects this trend to continue through the balance of the year. Cash used in the build of accounts receivable was partially offset by $12.9 million generated by the Corporation’s inventory management initiatives through the first six months of 2010.

During the third and fourth quarters of 2010, the Corporation will make required cash payments under certain retirement plans of $4.0 million and $11.2 million, respectively.
The seasonal nature of the construction aggregates business impacts quarterly operating cash flow when compared with the year. Full year 2009 net cash provided by operating activities was $318.4 million, compared with $116.7 million for the first six months of 2009.
Capital expenditures, exclusive of acquisitions, for the first six months were $68.6 million in 2010 and $74.8 million in 2009. Full-year capital spending for 2010 is expected to be approximately $135 million, including the Hunt Martin Materials joint venture but exclusive of acquisitions, a $25 million reduction from management’s previous guidance. Comparable full-year capital expenditures were $139.2 million in 2009.
During the six months ended June 30, 2010, the Corporation spent $28.1 million on acquisitions, primarily on the acquisition of a deep-water port operation located at Port Canaveral in Florida. This facility is currently the only developed deep-water aggregates import terminal located on the central east coast of Florida. From this location, the Corporation can ship product into the greater Orlando area, the second-largest aggregates consuming area in Florida. This acquisition complements the Corporation’s existing long-haul rail network.
At June 30, 2010, the Corporation had outstanding borrowings of $25.0 million under its $100 million secured accounts receivable credit facility (the “AR Credit Facility”). Borrowings under the AR Credit Facility are limited based on the balance of the Corporation’s accounts receivable.
In April 2010, the Corporation repaid $217.6 million of Floating Rate Senior Notes through the use of cash and short-term borrowings.
At June 30, 2010, the Corporation had $244.1 million of current maturities of long-term debt as $242.1 million of 6.875% Notes were reclassified to current to reflect their maturity date of April 2011. Management believes it has the ability to refinance the Notes when they become due.

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, 2010 or 2009. Management currently has no intent to repurchase any shares of its common stock. At June 30, 2010, 5,042,000 shares of common stock were remaining under the Corporation’s repurchase authorization.
The Corporation’s $325 million five-year revolving credit agreement (the “Credit Agreement”), $130 million unsecured term loan (the “Term Loan”) and $100 million AR Credit Facility are subject to a leverage ratio covenant. The covenant 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 months (the “Ratio”) to not exceed 3.50 to 1.00 as of the end of any fiscal quarter. Furthermore, the covenant allows the Corporation to exclude debt incurred in connection with acquisitions from the Ratio 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 the maximum Ratio plus 0.25. The Ratio is calculated as total long-term debt 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 items and noncash items, if they occur, can affect the calculation of consolidated EBITDA. At June 30, 2010, the Corporation’s ratio of consolidated debt to consolidated EBITDA, as defined, for the trailing twelve months EBITDA was 2.84 times and was calculated as follows (dollars in thousands):

In the event of a default on the leverage ratio, the lenders can terminate the Credit Agreement, Term Loan and AR Credit Facility and declare any outstanding balances 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 June 30, 2010, the Corporation had $323 million of unused borrowing capacity under its Credit Agreement and $75 million of available borrowings on its AR Credit Facility, subject to complying with the related leverage covenant. Of the $398 million of unused borrowing capacity, $199 million, or 50%, has been committed from Wells Fargo Bank, N.A. and Wachovia Bank, N.A. under commitments entered into prior to Wells Fargo Bank, N.A.’s acquisition of Wachovia Bank, N.A. Management does not expect any material change in this commitment prior to the expiration of the facilities. The Credit Agreement expires on June 30, 2012 and the AR Credit Facility terminates on April 20, 2012.
The Corporation may be required to obtain financing in order to fund certain strategic acquisitions, if any such opportunities arise, or to refinance outstanding debt. Any strategic acquisition of size would require an appropriate balance of newly-issued equity with debt in order to maintain an investment-grade credit rating. Borrowings under the AR Credit Facility would be limited based on the balance of the Corporation’s accounts receivable. Furthermore, the Corporation is exposed to the credit markets, through the interest cost related to its AR Credit Facility and Term Loan and the interest cost related to its commercial paper program, to the extent that it is available to the Corporation. Currently, the Corporation’s senior unsecured debt is rated BBB+ by Standard & Poor’s and Baa3 by Moody’s. The Corporation’s commercial paper obligations are rated A-2 by Standard & Poor’s and P-3 by Moody’s. While management believes its credit ratings will remain at an investment-grade level, no assurance can be given that these ratings will remain at those levels.
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, 2009, filed with the Securities and Exchange Commission on February 26, 2010. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

OUTLOOK Management’s outlook for the Corporation in 2010 has improved based on improving stability and expected growth in overall aggregates demand through the remainder of the year. Evidence of that stability was reflected in the Aggregates business’ second-quarter aggregates shipments. Management expects volumes sold to the infrastructure construction market to continue to increase as recipients of ARRA funds initiate projects to which monies have been obligated. For the full year, management expects: (i) infrastructure construction volume to be up 8% to 12%; (ii) nonresidential construction volume to decline 12% to 15%, improved from management’s earlier forecast; (iii) residential construction volume to be up 12% to 15%; and (iv) growth of 10% for the Corporation’s ChemRock/Rail products.
Considering all these factors, the Corporation is revising its full-year volume guidance upward. Management expects aggregates volume growth of 4% to 6%, aggregates pricing to range from down 1% to down 3% and aggregates production cost per ton to remain flat in 2010 compared with the prior year. This combination should lead to increased aggregates sales and improved gross margin and profitability in 2010. Energy costs, primarily diesel fuel consumed by off-road mobile quarry equipment, are likely to increase slightly compared with 2009. Management expects the Specialty Products segment to contribute $46 million to $48 million in pretax earnings for 2010. Interest expense should be approximately $70 million in 2010. Consistent with results for the first six months of 2010, management expects an increased use of cash for working capital, most notably accounts receivable, as revenues grow.
Although it is too early to issue guidance for 2011, management has begun to frame its initial view. Stability in federal funding for infrastructure is a critical issue moving into 2011 and the Corporation is operating under a Congressional continuing resolution that extended the Safe, Accountable, Flexible and Efficient Transportation Equity Act — A Legacy for Users (SAFETEA-LU) through December 31, 2010. Early in 2010, management was hopeful that a significantly increased Highway Bill would be passed by the lame-duck Congress after elections in November. Such a process had historic precedent in both the 1980s and 1990s when the existing Highway Bills were reauthorized, each at notably higher funding levels which were financed by increased user fees. However, a recent report issued by the Congressional Budget Office (the “CBO Report”) stated that the existing Highway Trust Fund could maintain the current level of spending for two years. Thus, management now believes the CBO Report will serve to make reauthorization a less pressing issue for politicians already reluctant to increase spending. Accordingly, management believes working under some form of a Congressional continuing resolution of SAFETEA-LU for 2011 is likely. Management still expects to see approximately 30% in ARRA infrastructure funds spent in 2011 together with an extended federal highway bill that will keep spending at constant funding levels. The Corporation also expects to see improvement in the residential construction market and it expects nonresidential construction to trough in 2010, with modest 2011 volume recovery.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
Second Quarter Ended June 30, 2010
(Continued)
The 2010 estimated outlook includes management’s assessment of the likelihood of certain risk factors that will affect performance. The most significant risk to 2010 performance will be, as previously noted, the strength of the United States economy and its impact on construction activity. The Corporation’s 2010 outlook is based on the expectation that the United States economy will continue to stabilize and positive economic growth will commence in the second half of the year.
Risks to the Corporation’s future performance are related to both price and volume and include a more widespread decline in aggregates pricing, a decline in infrastructure construction as a result of unexpected delays in federal ARRA and state infrastructure projects and continued lack of clarity regarding the timing and amount of the federal highway bill, a continued decline in commercial construction, a decline in residential construction, or some combination thereof. Further, increased highway construction funding pressures as a result of either federal or state issues can affect profitability. Currently, nearly all states are experiencing state-level funding pressures driven by lower tax revenues and an inability to finance approved projects. North Carolina and Texas are among the states experiencing these pressures, and these states disproportionately affect revenue and profitability.
The Corporation’s principal business serves customers in construction aggregates-related markets. This concentration could increase the risk of potential losses on customer receivables; however, payment bonds normally posted by the Corporation’s customers 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 prices, both directly and indirectly. Diesel and other fuels change production costs directly through consumption or indirectly in the increased cost of energy-related consumables, among them, steel, explosives, tires and conveyor belts. Fluctuating diesel pricing also affects transportation costs, primarily through fuel surcharges in the Corporation’s long-haul distribution network. The Corporation’s estimated outlook does not include rapidly increasing diesel costs during the remainder of 2010.
The availability of transportation in the Corporation’s long-haul network, particularly the availability of barges on the Mississippi River system and the availability of rail cars and locomotive power to move trains, affects the Corporation’s ability to efficiently transport material into certain markets, most notably Texas, Florida and the Gulf Coast region. The Aggregates business is also subject to weather-related risks that can significantly affect production schedules and profitability. Hurricane activity in the Atlantic Ocean and Gulf Coast generally is most active during the third and fourth quarters.

Risks to the 2010 outlook include volume decline as a result of economic events outside of 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.

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; widespread decline in aggregates pricing; the level and timing of federal and state transportation funding, including federal stimulus projects and most particularly in North Carolina, one of the Corporation’s largest and most profitable states, and Georgia, Texas, Iowa and Louisiana, which when coupled with North Carolina, represented 56% of 2009 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; the severity of a continued decline in the commercial construction market, notably office and retail space, and the continued decline in residential construction; 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 in the markets served by the Corporation; the volatility of fuel costs, particularly diesel fuel, and the impact on the cost of other consumables, namely steel, explosives, tires and conveyor belts; continued increases in the cost of other repair and supply parts; transportation availability, notably barge availability on the Mississippi River system and 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 costs and higher volumes of rail and water shipments; weakening in the steel industry markets served by the Corporation’s dolomitic lime products; inflation and its effect on both production and interest costs; changes in tax laws, the interpretation of such laws and/or administrative practices that would increase the Corporation’s tax rate; violation of the debt covenant if price and volume decline worse than expected; downward pressure on the Corporation’s common stock price and its impact on goodwill impairment evaluations; and other risk factors listed from time to time found in the Corporation’s filings with the Securities and Exchange Commission. Other factors besides those listed here may also adversely affect the Corporation, and may be material to the Corporation. The Corporation assumes no obligation to update any such forward-looking statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
The Corporation’s operations are highly dependent upon the interest rate-sensitive construction and steelmaking industries. Consequently, these marketplaces could experience lower levels of economic activity in an environment of rising interest rates or escalating costs.
Management has considered the current economic environment and its potential impact to the Corporation’s business. Demand for aggregates products, particularly in the commercial and residential construction markets, could continue to decline if companies and consumers are unable to obtain financing for construction projects or if the economic recession 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 at zero percent during 2009; the rate remains unchanged in 2010. The residential construction market accounted for approximately 7% of the Corporation’s aggregates product line shipments in 2009.
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 counterparty risk.
Variable-Rate Borrowing Facilities. The Corporation’s variable-rate borrowing facilities include a $325 million Credit Agreement which supports its commercial paper program, a $100 million AR Credit Facility and a $130 million Term Loan. Borrowings under these facilities and the commercial paper program bear interest at a variable interest rate. A hypothetical 100-basis-point increase in interest rates on outstanding borrowings of $136.8 million, which is the outstanding balance at June 30, 2010, would increase interest expense by $1.4 million on an annual basis. Wells Fargo Bank, N.A. and Wachovia Bank, N.A. have collective commitments of $200 million under the Corporation’s variable-rate borrowing facilities.
Pension Expense. The Corporation’s results of operations are affected by its pension expense. Assumptions that affect this expense include the discount rate and 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, 2009, filed with the Securities and Exchange Commission on February 26, 2010.

Energy Costs. Energy costs, including diesel fuel, natural gas and liquid asphalt, represent significant production costs for the Corporation. Increases in the prices of these products generally are tied to energy sector inflation. In 2009, decreases in the prices of these products compared with 2008 positively affected earnings per diluted share by $0.50. A hypothetical 10% change in the Corporation’s energy costs in 2010 as compared with 2009, assuming constant volumes, would impact 2010 pretax earnings by approximately $13.1 million.
Aggregate Risk for Interest Rates and Energy Costs. Pension expense for 2010 was calculated based on assumptions selected at December 31, 2009. Therefore, interest rate risk in 2010 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 the $136.8 million of variable-rate borrowings outstanding at June 30, 2010 would be an increase of $1.4 million in interest expense in 2010. Additionally, a 10% change in energy costs would impact annual pretax earnings by $13.1 million.
Item 4. Controls and Procedures
As of June 30, 2010, 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, 2010. 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.
