CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.	Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements of Martin Marietta Materials, Inc. (the “Corporation”) have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and to Article 10 of Regulation S-X. The Corporation has continued to follow the accounting policies set forth in the audited consolidated financial statements and related notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2011, filed with the Securities and Exchange Commission on February 29, 2012. In the opinion of management, the interim financial information provided herein reflects all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the results of operations, financial position and cash flows for the interim periods. The results of operations for the quarter and six months ended June 30, 2012 are not indicative of the results expected for other interim periods or the full year. The balance sheet at December 31, 2011 has been derived from the audited financial statements at that date but does not include all of the information and notes required by generally accepted accounting principles for complete financial statements. These 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, 2011.

Warranties

The Corporation’s construction contracts contain warranty provisions covering defects in equipment, materials, design or workmanship that generally run from six months to two years after the customer accepts the contract. Because of the nature of its projects, including contract owner inspections of the work both during construction and prior to acceptance, the Corporation has not experienced material warranty costs for these warranties and therefore does not believe an accrual for these costs is necessary.

Consolidated Comprehensive Earnings/Loss and Accumulated Other Comprehensive Loss

Consolidated comprehensive earnings/loss for the Corporation consist of consolidated net earnings or loss; adjustments for the funded status of pension and postretirement benefit plans; foreign currency translation adjustments; and the amortization of the value of terminated forward starting interest rate swap agreements into interest expense.

Consolidated Comprehensive Earnings/Loss and Accumulated Other Comprehensive Loss (continued)

Effective January 1, 2012, as required by recent accounting guidance, the Corporation changed its presentation of consolidated comprehensive earnings/loss. The Corporation no longer reports total consolidated comprehensive earnings/loss and related components of other comprehensive earnings/loss in its consolidated statement of total equity. Rather, the Corporation presents total consolidated comprehensive earnings/loss in its consolidated statements of earnings and comprehensive earnings for interim periods and in separate but consecutive consolidated statements of comprehensive earnings for annual periods. Prior-year information has been recast to conform to this presentation approach.

Comprehensive earnings attributable to Martin Marietta Materials Inc. consist of the following:

Earnings (Loss) per Common Share

The numerator for basic and diluted earnings (loss) per common share is net earnings (loss) 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 (loss) per common share is the weighted-average number of common shares outstanding during the period. Diluted earnings (loss) 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, 2012 and 2011 and the six months ended June 30, 2011, 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:


		Three Months Ended June 30,					Six Months Ended June 30,
		2012		2011			2012			2011

2.	Discontinued Operations

Divestitures and Permanent Closures

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

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

5.	Long-Term Debt (continued)

On January 23, 2012, the Corporation repurchased $20,000,000 par value of its outstanding 6.25% Senior Notes due 2037 at 90.75. This repurchase was financed with borrowings of $18,200,000 under the Corporation’s Revolving Facility.

On April 13, 2012, the Corporation renewed its AR Credit Facility for a one-year term ending April 20, 2013.

The Credit Agreement (which consists of the Term Loan Facility and a $350,000,000 Revolving Facility) and the AR Credit Facility require the Corporation’s ratio of consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing twelve month period (the “Ratio”) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Corporation may exclude from the Ratio debt incurred in connection with certain acquisitions for a period of 180 days so long as the Corporation maintains specified ratings on its long-term unsecured debt and the Ratio calculated without such exclusion does not exceed 3.75x. Additionally, if no amounts are outstanding under both the Revolving Facility and the AR Credit Facility, consolidated debt, including debt guaranteed by the Corporation, may be reduced by the Corporation’s unrestricted cash and cash equivalents in excess of $50,000,000, such reduction not to exceed $200,000,000, for purposes of the covenant calculation.

In 2012, the Corporation amended the Ratio to ensure that the impact of business development costs and the seasonal working capital requirements of the Corporation’s acquired Colorado operations do not impair liquidity available under the Corporation’s Credit Agreement and AR Credit Facility. The amendments temporarily increase the maximum Ratio to 3.95x at June 30, 2012, before stepping down to 3.75x at September 30, 2012. The Ratio returns to the pre-amendment maximum of 3.50x for the December 31, 2012 calculation date. The amendments also allow the Corporation to exclude debt associated with the acquired Colorado operations from the Ratio at June 30, 2012.

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, 2012, the Corporation had $2,507,000 of outstanding letters of credit issued under the Revolving Facility.

Accumulated other comprehensive loss includes the unamortized value of terminated forward starting interest rate swap agreements. For the three and six months ended June 30, 2012, the Corporation recognized $257,000 and $508,000, respectively, as additional interest expense. For the three and six months ended June 30, 2011, the Corporation recognized $239,000 and $474,000, 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.

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, 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, Georgia and South Carolina, which accounted for approximately 57% of the Aggregate business’ 2011 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 carrying values and fair values of the Corporation’s long-term debt were $1,144,247,000 and $1,204,965,000, respectively, at June 30, 2012; $1,060,084,000 and $1,087,726,000, respectively, at December 31, 2011; and $1,085,915,000 and $1,053,281,000, respectively, at June 30, 2011. The estimated fair value of the Corporation’s publicly-registered long-term notes was estimated based on level 1 of the fair value hierarchy, quoted market prices. The estimated fair value of other borrowings, which primarily represent variable-rate debt, approximates its carrying amount.

7.	Income Taxes


	Six Months Ended June 30,
	2012		2011
Estimated effective income tax rate:
Continuing operations		145.5%		27.3%

Discontinued operations		21.2%		30.0%

Consolidated overall		110.6%		26.9%

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 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. The consolidated overall estimated effective income tax rate for the six months ended June 30, 2012 would have been 21.1% without this discrete event; a rate more reflective of the expected annual tax rate of 23%. The consolidated overall estimated effective income tax rate for the six months ended June 30, 2011 included the following discrete events: resolution of a federal tax and interest overpayment of $1,730,000 related to the 2006 tax year and an agreed-upon refund of $1,060,000 for the double taxation of the Corporation’s wholly-owned Canadian subsidiary for the 2001 and 2002 tax years.

On December 23, 2011, the U.S. Treasury Department issued comprehensive temporary and proposed regulations addressing the treatment of expenditures related to tangible property for tax purposes. On March 7, 2012, the Internal Revenue Service (“IRS”) issued two revenue procedures containing administrative guidance related to the adoption of the new rules. Although the regulations are generally effective for tax years beginning January 1, 2012, the IRS has granted taxpayers administrative relief and audit protection for a two-year period as long as the taxpayer adopts the regulations retroactively within two years of the effective date. Management has begun to evaluate the changes necessary to comply with the regulations and the related administrative procedures and is not currently aware of any adjustments that would be material to the Corporation’s consolidated financial position and results of operations. As part of its compliance with these regulations, the Corporation reversed its unrecognized tax benefits related to repairs and maintenance as of March 31, 2012.

Unrecognized tax benefits at end of period		$ 5,128

At June 30, 2012, unrecognized tax benefits of $5,876,000, net of federal tax benefits and related to interest accruals and permanent income tax differences, would have favorably affected the Corporation’s effective income tax rate if recognized.

Legal and Administrative Proceedings

The Corporation is engaged in certain legal and administrative proceedings incidental to its normal business activities. In the opinion of management and counsel, based upon currently-available facts, it is remote that the ultimate outcome of any litigation and other proceedings, including those pertaining to environmental matters, relating to the Corporation and its subsidiaries, will have a material adverse effect on the overall results of the Corporation’s operations, its cash flows or its financial position.

On May 4, 2012, the Court of Chancery of the State of Delaware issued an opinion and on May 14, 2012, it entered a final order and judgment pursuant to which, among other things, the Corporation was enjoined for a period of four months from prosecuting a proxy contest, making an exchange or tender offer, or otherwise taking steps to acquire control of Vulcan Materials Company (“Vulcan”) shares or assets. In accordance with this order, the Corporation terminated its exchange offer for Vulcan shares and its proxy solicitation to elect four nominees to the board of directors of Vulcan. The Delaware Supreme Court affirmed the Court of Chancery decision on May 31, 2012.

Environmental and Governmental Regulations

In 2010, the United States Environmental Protection Agency (“USEPA”) included 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 reasonable likely penalties or required upgrades to equipment might ultimately be required. The Corporation believes that any costs related to any required upgrades will be spread over time and will not have a material adverse effect on the Corporation’s operations or its financial condition, but can give no assurance that the ultimate resolution of this matter will not have a material adverse effect on the financial condition or results of operations of the Specialty Products segment of the business.

Guarantee of Affiliate

The Corporation has an unconditional guaranty of payment agreement with Fifth Third Bank (“Fifth Third”) to guarantee the repayment of amounts borrowed by an affiliate under a $24,000,000 revolving line of credit provided by Fifth Third that expires in July 2013 and a guaranty agreement with Bank of America, N.A., to guarantee a $6,200,000 amortizing loan due April 2016. The affiliate has agreed to reimburse and indemnify the Corporation for any payments and expenses the Corporation may incur from these agreements. The Corporation holds a subordinate lien of the affiliate’s assets as collateral for potential payments under the agreements.

10.

Business Segments

The Corporation conducts its aggregates operations through three reportable business segments: Mideast Group, Southeast Group and West Group. The Corporation also has a Specialty Products segment that includes magnesia-based chemicals products and dolomitic lime. These segments are consistent with the Corporation’s current management reporting structure.

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

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

Second Quarter Ended June 30, 2012

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 303 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 nonresidential and residential building development. Aggregates products are also used in the railroad, environmental, utility and agricultural industries. 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, 2011, filed with the Securities and Exchange Commission (“SEC”) on February 29, 2012. There were no changes to the Corporation’s critical accounting policies during the six months ended June 30, 2012.

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, 2012 and 2011 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales (dollars in thousands):

The Corporation’s second-quarter results once again reflect the powerful combination of increases in shipment volumes and average selling prices in the heritage aggregates product line, which led to a 150-basis-point improvement in the heritage aggregates business operating margin (excluding freight and delivery revenues). Underlying these increases are continuing indications of recovery in certain of the Corporation’s markets, predominantly in the western United States. In particular, heritage volume growth in Texas was driven by increased shipments to both the energy sector and the residential end-use market. Additionally, the Specialty Products business reported strong results, establishing a new second-quarter record for net sales. Looking ahead, the positive momentum generated in the first half of the year, together with the recent passage of a new federal highway bill and regionalized improvement in homebuilding, have bolstered the Corporation’s optimism for construction activity.

For the quarter, heritage aggregates product line shipments increased 2.8% over the prior-year period. This growth was led by a 7.6% increase in the West Group, with heritage volumes particularly strong in Texas, driven by robust construction activity, and in the Corporation’s Midwest Division, particularly Iowa, where the mild winter permitted an early start to the construction season. The Mideast Group reported heritage volume growth of 2.9%, with heavy highway projects in the Indiana and Ohio markets offsetting declines in the North Carolina markets where construction project delays have shifted work originally planned for the second quarter into the second half of the year. The Southeast Group experienced a 10.1% decline in heritage aggregates product line shipments resulting from economic growth in the region lagging national trends, principally due to weak job growth and continued high foreclosure rates.

Notably, heritage aggregates product line shipments increased 8% in April and May over the prior-year two-month period. In that volume environment, an incremental gross margin (excluding freight and delivery revenues) consistent with management’s expectations was achieved. In June, however, shipments declined 5.5%, indicative of previously-mentioned project delays, coupled with uncertainty in the current economic environment. As expected, this erratic volume pattern, together with planned inventory reduction, diluted the incremental gross margin gains from the first two months of the quarter. However, management is pleased with the 150-basis-point expansion of operating margin (excluding freight and delivery revenues) in the heritage aggregates business for the quarter.

Heritage shipments in the infrastructure end-use market, which represents more than half of the Aggregates business, increased 3% for the quarter. Management was gratified to see the Moving Ahead for Progress in the 21^st Century Act, or MAP-21, signed into law earlier in the month. MAP-21 is a two-year federal surface transportation bill intended to expedite project approvals and limit spending for programs outside of core transportation needs. The bill provides highway expenditures at current levels, $40 billion per year, with modest increases to reflect projected inflation and reform provisions. The funding provided by this multi-year bill brings a degree of fiscal certainty to those states, counties and municipalities that were subjected to a series of short-term continuing federal resolutions since 2009 and hesitant to initiate needed infrastructure projects. While the impact of MAP-21 is not expected to generate meaningful construction activity in 2012, management fully anticipates that the Corporation’s aggregates shipments will increase over the next several years, with more clarity into the magnitude of that increase as the late summer/early fall state Department of Transportation project lettings become available.

Shipments to the heritage nonresidential end-use market increased 8% over the prior-year quarter, with growth attributable to heavy industrial activity, particularly in the energy sector. The heritage residential end-use market continues to recover from the depressed levels experienced in recent years. For the quarter, heritage shipments to this market rose 21%, reflecting the increase in national year-to-date housing starts. Finally, the heritage ChemRock/Rail end-use market declined 19% versus the prior-year quarter. The reduction is principally due to the comparison with an unusually strong quarter for ballast shipments in 2011 as well as project delays related to track maintenance schedules in the current year. The Corporation expects to recover certain of these shipments in the second half of the year.

The Corporation continues to see positive construction trends in the Denver, Colorado market, which it entered in December 2011. The rate of growth in highway contract awards in Colorado ranks among the highest in the country and, importantly, construction-related employment is growing at twice the national average. Nonresidential construction activity also continues to improve with commercial real estate realizing increased lease rates and decreasing vacancies. Year-to-date housing permits in the state increased nearly 70%, outpacing the national average; while single-family home sales have increased significantly over the prior-year period. Despite the later start of the construction season due to the increased exposure to winter weather, the Colorado operations once again exceeded management’s expectations and had break-even profitability for the quarter.

The heritage aggregates product line average selling price grew 2.4% over the prior-year quarter. The West Group had the highest rate of increase, 5.4%, driven by shipments to the energy sector. These shipments are primarily from sales yards which have higher average selling prices than producing quarries due to internal freight costs. The Southeast Group reported a 4.7% heritage pricing increase despite a volume decline, with particular strength at its Bahamas facility, which is providing aggregates for a significant nonresidential project. The average selling price for the Mideast Group increased 1.5%, excluding a 240-basis-point reduction in pricing due to geographic mix.

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.

The Aggregates business is significantly affected by erratic weather patterns, seasonal changes and other weather-related conditions. Aggregates production and shipment levels coincide with general construction activity levels, most of which occurs in the spring, summer and fall. Thus, production and shipment levels vary by quarter. Operations concentrated in the northern and midwestern United States generally experience more severe winter weather conditions than operations in the Southeast and Southwest. Operations in the Denver, Colorado area increase the Corporation’s exposure to winter weather and the risk of losses in the first and fourth quarters. 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 continues to experience strong demand in both the chemicals and dolomitic lime product lines. For the quarter, net sales of $50.5 million increased 1.7% and established a new second-quarter record. Earnings from operations of $17.5 million, or 34.6% of net sales, compared with earnings from operations of $19.3 million in the second quarter of 2011, reflect higher costs incurred for raw materials, contract services and repairs.

Planned inventory reductions in the heritage aggregates product line drove a 1.3% increase in cost per ton during the quarter. However, contrary to a multi-quarter trend of increases, energy costs were essentially flat as the Corporation paid an average of $3.03 per gallon of diesel fuel compared with $3.08 in the prior-year quarter. Cumulatively, direct production costs for the heritage aggregates product line increased slightly.

The Corporation’s consolidated gross margin (excluding freight and delivery revenues) for the quarter was 20.8%, a 300-basis-point decline compared with the prior-year quarter primarily attributable to inventory control measures. The following presents a rollforward of the Corporation’s gross profit (dollars in thousands):


Consolidated gross profit, quarter ended June 30, 2011	$	97,543

Heritage Aggregates Product Line:
Volume strength		9,346

Consolidated gross profit, quarter ended June 30, 2012	$	102,088

Nonproduction costs for the heritage aggregates product line include freight expenses to transport materials from a producing quarry to a distribution yard and resale material. During the quarter, internal rail freight costs increased due to additional volumes being shipped to materials yards, particularly in the West Group. Additionally, during the quarter, the Corporation’s Mideast Group operations were unable to produce enough material to support well drilling for the oil and gas industry and purchased these products for its customers, incurring incremental resale material costs of $2.9 million over the prior-year quarter. The Mideast Group should see resale material purchases moderate over the next quarter as certain quarries are brought back on line following planned upgrades.

Inventory change is the difference between the prior period’s ending inventory and the current period’s ending inventory. In periods in which inventory decreases, inventory change will increase cost of sales, as capitalized production costs are recognized into earnings. Conversely, in periods in which inventory increases, inventory change will reduce cost of sales. During the twelve-month period ended June 30, 2012, the Corporation adjusted production and reduced heritage aggregates product line inventory levels as part of planned inventory control initiatives. At June 30, 2012 and 2011, heritage aggregates inventory on hand was 59.7 million tons and 63.4 million tons, respectively.

Consolidated SG&A expenses were 7.2% of net sales, a 40-basis-point reduction compared with the prior-year quarter. On an absolute basis, SG&A expenses increased $4.3 million, as expected, primarily attributable to overhead incurred at our Denver operations and costs related to an information systems upgrade expected to be completed by the fall of 2013.

During the second quarter 2012, the Corporation incurred $9.2 million of business development costs related to the Corporation’s proposed business combination with Vulcan Materials Company (“Vulcan”). On May 4, 2012, the Court of Chancery of the State of Delaware issued an opinion and, on May 14, 2012, it entered a final order and judgment pursuant to which, among other things, the Corporation was enjoined for a period of four months from prosecuting a proxy contest, making an exchange or tender offer, or otherwise taking steps to acquire control of Vulcan shares or assets. In accordance with this order, the Corporation terminated its exchange offer for Vulcan shares and its proxy solicitation to elect four nominees to the board of directors of Vulcan. The Delaware Supreme Court affirmed the Court of Chancery decision on May 31, 2012.

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; 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 $1.7 million in 2012 compared with an expense of $0.1 million in 2011, primarily as a result of higher gains on the sale of assets in during the second quarter of 2012.

For the first six months, net sales for the Aggregates business were $739.6 million in 2012 versus $601.5 million in 2011, primarily due to the acquisition of operations in Denver, Colorado, and growth in the Corporation’s nonresidential and residential end-use markets. Shipments to the heritage nonresidential end-use market increased 11% as energy-sector activity continues to grow. The residential end-use market continues to recover from the depressed levels of the past few years, reflecting the increase in national year-to-date housing permits. For the six-month period ended June 30, 2012, heritage aggregates volume increased 5.5%, while pricing increased 2.6%.

Increased direct production costs and nonproduction costs for the heritage aggregates product line, coupled with the Corporation’s increased exposure to vertically-integrated business, reduced the Corporation’s gross margin (excluding freight and delivery revenues) for the six months ended June 30 by 220 basis points to 15.0% in 2012.

The heritage aggregates product line continues to absorb the significant financial impact of higher energy expenses, particularly diesel fuel, which represents the single largest component of its energy costs. For the first six months, the Aggregates business paid an average of $3.14 per gallon in 2012 compared with $2.95 in the prior-year period.

For the six months ended June 30, 2012, other production costs for the heritage aggregates product line increased $12.1 million over the prior-year period due to higher costs for labor, repairs, supplies and royalty expenses. Direct production costs per ton increased 1% over the comparable prior-year period as increased year-to-date production improved operating efficiency.

Nonproduction costs for the heritage aggregates product line increased $17.0 million compared with the prior-year period. Internal freight costs for the heritage aggregates operations increased $9.9 million compared with the prior-year period. While higher diesel fuel costs experienced during the first quarter contributed to the increase in internal freight costs, the rail component increased due to increased shipments to materials yards, particularly in the West Group. Additionally, resale material costs increased significantly as the Corporation has been unable to produce enough material to support well drilling for the oil and gas industry, particularly in the Mideast Group, and purchased the products for its customers.

Consolidated SG&A expenses were 8.1% of net sales, a 40-basis-point reduction compared with the prior-year period. On an absolute basis, SG&A expenses increased $8.7 million, as expected, primarily related to the acquired operations in the Denver, Colorado market.

During the six months ended June 30, 2012, the Corporation incurred $35.1 million of business development costs.

For the six months ended June 30, consolidated other operating income and expenses, net, was income of $1.5 million in 2012 compared with income of $2.4 million in 2011, primarily as a result of higher gains on the sale of assets in 2011.

Interest expense was $26.7 million for the six months ended June 30, 2012 compared with $31.9 million for the prior-year period. The decrease in 2012 was due to a higher mix of variable-rate debt which currently bears a lower interest rate than the Corporation’s fixed-rate debt.

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 income of $1.9 million in 2012 compared with an expense of $0.1 million in 2011, primarily as a result of a bond repurchase at a discount in 2012.

LIQUIDITY AND CAPITAL RESOURCES

Excluding the impact of business development expenses, cash provided by operating activities for the six months ended June 30 was $52.6 million in 2012 compared with $56.7 million for 2011. 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:

Additionally, the Corporation’s December 2011 asset exchange changed the timing of cash flows throughout the year, with increased cash flows generated by the Denver operations expected to be realized later in the year. Cash used for operating activities by the Denver operations was approximately $39 million during the first six months of 2012. Days sales outstanding was 43 days, down from 44 days in 2011.

The seasonal nature of the construction aggregates business impacts quarterly operating cash flow when compared with the full year. Full year 2011 net cash provided by operating activities was $259.1 million compared with $56.7 million for the first six months of 2011.

Capital expenditures, exclusive of acquisitions, for the first six months were $66.3 million in 2012 and $58.7 million in 2011. During 2012, the Corporation incurred $22 million for the construction of a dolomitic lime kiln at its Specialty Products location in Woodville, Ohio. This project is expected to be substantially completed during the fourth quarter. Once completed, the new kiln is expected to generate annual net sales ranging from $22 million to $25 million. Full-year capital spending, exclusive of acquisitions, if any, is expected to be approximately $155 million. Comparable full-year capital expenditures were $155.4 million in 2011.

On January 23, 2012, the Corporation repurchased $20.0 million par value of its outstanding 6.25% Senior Notes due 2037 at 90.75. This repurchase was financed with borrowings of $18.2 million under the Corporation’s Revolving Facility.

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, 2012 and 2011. Management currently has no intent to repurchase any shares of its common stock. At June 30, 2012, 5,042,000 shares of common stock were remaining under the Corporation’s repurchase authorization.

The Credit Agreement (which consists of the Term Loan Facility and a $350 million Revolving Facility) and the AR Credit Facility require the Corporation’s ratio of consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing twelve month period (the “Ratio”) to not exceed 3.5x as of the end of any fiscal quarter, provided that the Corporation may exclude from the Ratio debt incurred in connection with certain acquisitions for a period of 180 days so long as the Corporation, as a consequence of such specified acquisition, does not have its ratings on long-term unsecured debt fall below BBB by Standard & Poor’s or Baa2 by Moody’s and the Ratio calculated without such exclusion does not exceed 3.75x. Additionally, if there are no amounts outstanding under both the Revolving Facility and the AR Credit Facility, consolidated debt, including debt guaranteed by the Corporation, will be reduced for purposes of the covenant calculation by the Corporation’s unrestricted cash and cash equivalents in excess of $50 million, such reduction not to exceed $200 million (hereinafter, “net debt”).

In 2012, the Corporation amended the Ratio to ensure that the impact of business development costs and the seasonal working capital requirements for the acquired Colorado operations do not impair liquidity available under the Corporation’s Credit Agreement and AR Credit Facility. The amendments temporarily increase the maximum Ratio to 3.95x at June 30, 2012, stepping down to 3.75x at September 30, 2012. The Ratio returns to the pre-amendment maximum of 3.50x for the December 31, 2012 calculation date. The amendments also allow the Corporation to exclude debt associated with the acquired Colorado operations from the Ratio at June 30, 2012, which was allowed only through the March 31, 2012 calculation date prior to the amendments.

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.

At June 30, 2012, the Corporation’s ratio of consolidated debt to consolidated EBITDA, as defined, for the trailing twelve months EBITDA was 3.63 times and was calculated as follows (dollars in thousands):


	Twelve Month Period July 1, 2011 to June 30, 2012

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

Cash on hand, along with the Corporation’s projected internal cash flows and availability of financing resources, including its access to debt and equity capital markets, are expected to continue to be sufficient to provide the capital resources necessary to support anticipated operating needs, cover debt service requirements, meet capital expenditures and discretionary investment needs, fund certain acquisition opportunities that may arise and allow for payment of dividends for the foreseeable future. At June 30, 2012, the Corporation had $202.5 million of unused borrowing capacity under its Revolving Facility, subject to complying with the related leverage covenant, and no available borrowings under its AR Credit Facility. The Credit Agreement expires on March 31, 2015 and the AR Credit Facility, as amended, terminates on April 20, 2013.

The Corporation may be required to obtain financing to fund certain strategic acquisitions, if any such opportunities arise, or to refinance outstanding debt. A strategic acquisition of size for cash would likely require an appropriate balance of newly-issued equity with debt in order to maintain an investment-grade credit rating. Furthermore, the Corporation is exposed to the credit markets, through the interest cost related to its variable-rate debt, which includes borrowings under its Revolving Facility, Term Loan Facility and AR Credit Facility, and the interest cost related to its commercial paper program, to the extent that it is available to the Corporation. The Corporation is currently rated by three credit rating agencies, and while two of those agencies’ credit ratings are investment-grade level, on July 12, 2012, the third agency reduced its rating to one level below investment grade. The Corporation’s composite credit rating remains at investment-grade level, which facilitates obtaining financing at lower rates than noninvestment-grade ratings. While management believes its composite credit ratings will remain at an investment-grade level, no assurance can be given that these ratings will remain at current levels.

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, 2011, filed with the Securities and Exchange Commission on February 29, 2012. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

On July 31, 2012, as part of the state of Georgia’s Transportation Investment Act of 2010, three special tax districts in the state approved a referendum to levy a 1% sales tax for 10 years to fund transportation projects in their districts. The combined projected revenues from the tax for the three districts are $1.8 billion over the 10-year period.

OUTLOOK

With the challenges of 2011 and the first half of 2012 behind the Corporation, management remains optimistic for the Corporation’s second half performance and outlook for 2013. The passage of MAP-21, which is essentially a final three-month continuing resolution through September 30, 2012, followed by a two-year federal highway bill, provides the Corporation with a solid foundation for infrastructure construction. Since, as previously stated, the Corporation does not expect a notable volume impact from this legislation before 2013, heritage infrastructure end-use market volume for full year 2012 are expected to range from flat to down slightly. Management anticipates double-digit volume growth in the heritage nonresidential end-use market, driven primarily by increased energy shipments, although some energy-sector activity will continue to be affected by natural gas prices, the timing of lease commitments for oil and natural gas companies, geographic transitions and weather conditions. The rate of improvement in the heritage residential end-use market is expected to accelerate over the rate of improvement in 2011. Finally, heritage ChemRock/Rail shipments should be flat to down slightly.

As such, management anticipates heritage aggregates product line shipments for the full year to increase 4% to 5% and pricing to increase 2% to 4%. A variety of factors beyond the Corporation’s direct control may exert pressure on aggregates volumes and the forecasted pricing increase is not expected to be uniform across the company. Heritage aggregates product line direct production costs per ton are expected to be flat compared with 2011 in spite of management’s expectation to reduce production as part of controlling inventory levels.

As previously communicated, the platform acquisition of the Denver, Colorado-based business is consistent with one of management’s core long-term strategies, which is to be in attractive growth areas with a leading market position – thereby permitting greater operational efficiencies, customer service and growth opportunities. Economic forecasts consistently show Denver’s population growing at a faster-than-average pace, with commensurate jobs growth, supporting management’s optimism for increased construction activity. Overall, as the Corporation integrates the Denver operations into its disciplined cost structure, management estimates that the asset exchange will be neutral to its full-year EBITDA. Management expects that this acquisition will be accretive in 2013.

Earnings for the Specialty Products segment should be approximately $68 million to $70 million. Steel utilization and natural gas prices are two key drivers for this segment.

(Continued)

SG&A expenses, excluding the incremental expense related to the acquired operations in Denver and systems upgrades, are expected to decline slightly. Management expects improvement in SG&A expenses related to the Denver operations as it completes the integration. Interest expense should remain relatively flat compared with 2011. The Corporation’s effective tax rate is expected to approximate 23%, excluding discrete events. Capital expenditures are forecast at $155 million, which includes the remainder of the $53 million Specialty Products kiln project.

The full-year estimated outlook includes management’s assessment of the likelihood of certain risk factors that will affect performance. The most significant risk to 2012 performance will be the United States economy and its impact on construction activity. 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 decline in nonresidential construction; a decline in 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. Currently, nearly all states have general fund budget pressures driven by lower tax revenues. If these pressures negatively affect transportation budgets more than in the past, construction spending could be reduced. North Carolina and Texas, states disproportionately affecting the Corporation’s revenue and profitability, are among the states experiencing these fiscal pressures, although recent statistics indicate that transportation budgets and tax revenues are increasing.

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 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 fuel and other consumables change production costs directly through consumption or indirectly by increased energy-related input costs, such as, steel, explosives, tires and conveyor belts. Fluctuating diesel fuel pricing also affects transportation costs, primarily through fuel surcharges in the Corporation’s long-haul distribution network. The Specialty Products business is sensitive to changes in domestic steel capacity utilization and the absolute price and fluctuations in the cost of natural gas. However, due to recent technology developments allowing the harvesting of abundant natural gas supplies in the U.S., natural gas prices have stabilized.

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

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

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

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 an 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 the quarter ended June 30, 2012. The residential construction market accounted for approximately 8% of the Corporation’s heritage aggregates product line shipments in 2011.

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.

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 $100 million AR Credit Facility. Borrowings under these facilities bear interest at a variable interest rate. A hypothetical 100-basis-point increase in interest rates on borrowings of $490 million, which is the collective outstanding balance at June 30, 2012, would increase interest expense by $4.9 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, 2011, filed with the Securities and Exchange Commission on February 29, 2012.

Energy Costs. Energy costs, including diesel fuel, natural gas and liquid asphalt, represent significant production costs for the Corporation. A hypothetical 10% change in the Corporation’s energy prices in 2012 as compared with 2011, assuming constant volumes, would impact annual 2012 pretax earnings by approximately $16.8 million.

Aggregate Risk for Interest Rates and Energy Costs. Pension expense for 2012 is calculated based on assumptions selected at December 31, 2011. Therefore, interest rate risk in 2012 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 $490 million of variable-rate borrowings outstanding at June 30, 2012 would increase interest expense on an annual basis by $4.9 million. Additionally, a 10% change in energy prices compared with 2011 would impact annual pretax earnings by $16.8 million.

Item 4. Controls and Procedures

As of June 30, 2012, 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. As permitted by the Securities and Exchange Commission, the Corporation’s management excluded its newly-acquired Denver operations from its evaluation of disclosure controls and procedures as of June 30, 2012. These Denver operations accounted for approximately 7% of the Company’s consolidated total assets at December 31, 2011. 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, 2012. 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.
