FORM 10-Q
For the Quarter Ended September 30, 2007

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, 2006, filed with the Securities and Exchange Commission on February 28, 2007. 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 for the nine months ended September 30, 2007 are not indicative of the results expected for other interim periods or the full year.

		Retirement Plans and Postretirement Benefits

		On December 31, 2006, the Corporation adopted the recognition and disclosure provisions of Statement of Financial Accounting Standards No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an Amendment of FAS 87, 88, 106 and 132(R) (“FAS 158”) prospectively. In connection with the adoption, the Corporation increased accumulated other comprehensive loss by $20,418,000, net of tax, at December 31, 2006 for the net unrecognized actuarial losses, unrecognized prior service costs and unrecognized transition assets remaining from the initial adoption of FAS 87 and FAS 106. During the nine months ended September 30, 2007, $1,705,000, net of tax, of these unrecognized amounts was recognized as a component of net periodic benefit cost pursuant to the Corporation’s historical accounting policy for amortizing such amounts.

		Uncertain Tax Positions

		Effective January 1, 2007, the Corporation adopted Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FAS 109 (“FIN 48”). FIN 48 requires the recognition of a tax benefit when it is “more-likely-than-not,” based on the technical merits, that the position would be sustained upon examination by a taxing authority. The amount to be recognized should be measured as the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Continued)

1.		Significant Accounting Policies (continued)

		Uncertain Tax Positions (continued)

		In connection with the adoption of FIN 48, the Corporation increased its reserves for uncertain tax positions and reduced retained earnings at January 1, 2007 by $1,407,000, primarily as a result of providing interest accruals on uncertain temporary tax positions related to temporary or timing differences.

		The adoption of FIN 48 affected the Corporation’s results of operations as follows:


	Three Months Ended		Nine Months Ended
	September 30, 2007		September 30, 2007
Decreased earnings from continuing operations and net earnings by:	$	554,000	$	1,985,000
Decreased basic and diluted earnings per share by:	$	0.01	$	0.05

The following table summarizes the Corporation’s FIN 48 unrecognized tax benefits:


	Adoption of FIN 48
	January 1, 2007		September 30, 2007
Total amount of gross unrecognized tax benefits, excluding interest	$	29,248,000	$	29,354,000
Unrecognized tax benefits, net of federal tax benefits, related to interest accruals and permanent income tax differences that would favorably affect the effective tax rate if recognized	$	10,577,000	$	7,026,000

		During the quarter ended September 30, 2007, the Corporation reduced its unrecognized tax benefits by $8,655,000 when the federal statute of limitations for examination of the 2003 tax year expired. Additionally, the Corporation increased its unrecognized tax benefits by $8,761,000 for current year tax positions during the nine months ended September 30, 2007.

		The Corporation anticipates that it is reasonably possible that the total amounts of unrecognized tax benefits may significantly change within the succeeding twelve months as a result of settlement of the Internal Revenue Service audits for the 2004 and 2005 tax years. The Corporation estimates that these events could result in a reasonably possible change in unrecognized tax benefits ranging from $0 to $10,029,000.

		The Corporation records interest accrued in relation to unrecognized tax benefits as income tax expense and penalties, if incurred, are recorded as other nonoperating expenses in the consolidated statement of earnings. Accrued interest of $4,030,000 and $4,698,000 was recorded as a current FIN 48 liability in the Corporation’s consolidated balance sheet at September 30, 2007 and January 1, 2007, respectively.

5.		Long-Term Debt (continued)

		On April 25, 2007, the Corporation issued $250,000,000 of 6.25% Senior Notes due in 2037 and $225,000,000 of Floating Rate Senior Notes due in 2010 (collectively, the “Senior Notes”). The 6.25% Senior Notes may be redeemed in whole or in part prior to their maturity at a “make whole” redemption price. The Floating Rate Senior Notes bear interest at a rate equal to the three-month LIBOR (5.36% at September 30, 2007) plus 0.15% and may not be redeemed prior to maturity. Upon a change of control repurchase event, the Corporation will be required to make an offer to repurchase all outstanding Senior Notes at a price in cash equal to 101% of the principal amount of the Senior Notes, plus any accrued and unpaid interest to, but not including, the purchase date.

		The Corporation refinanced its $125,000,000 6.9% Notes that matured in August 2007 with proceeds from its offering of public debt in April 2007 and issuances of commercial paper.

		The carrying values of the Notes due in 2008 included $2,766,000, $4,469,000 and $5,022,000 at September 30, 2007, December 31, 2006 and September 30, 2006, respectively, for the unamortized value of terminated interest rate swaps.

		The Corporation entered into two forward starting interest rate swap agreements in September 2006 related to $150,000,000 of the Corporation’s anticipated refinancing of its $200,000,000 5.875% Notes due in 2008 (the “Swap Agreements”). At September 30, 2007, the fair value of the Swap Agreements was a liability of $1,006,000 and was included in other noncurrent liabilities in the Corporation’s consolidated balance sheet. Other comprehensive earnings/loss for the three and nine months ended September 30, 2007 included a loss of $2,774,000 and a gain of $571,000, respectively, net of tax, for the change in fair value of the Swap Agreements. At December 31, 2006 and September 30, 2006, the fair value of the Swap Agreements was a liability of $1,951,000 and $1,862,000, respectively.

		Borrowings of $76,000,000 and $11,000,000 were outstanding under the commercial paper program at September 30, 2007 and 2006, respectively. No commercial paper borrowings were outstanding at December 31, 2006.

		At December 31, 2006 and September 30, 2006, borrowings of $537,000 and $1,190,000, respectively, were outstanding under a $10,000,000 line of credit. No such borrowings were outstanding at September 30, 2007.

5.		Long-Term Debt (continued)

		On April 17, 2007, the Corporation entered into an amendment of its $250,000,000 five-year revolving credit agreement, which modified the leverage ratio covenant in the agreement. As modified, 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 2.75 to 1.00 as of the end of any fiscal quarter. Furthermore, the covenant allows the Ratio to exclude debt incurred in connection with an acquisition for a period of 180 days, provided that the Ratio does not exceed 3.25 to 1.00. The Corporation was in compliance with the Ratio at September 30, 2007.

6.		Income Taxes


	Nine Months Ended September 30,
	2007			2006
Estimated effective income tax rate:
Continuing operations		29.6	%		29.8	%

Discontinued operations		46.8	%		(8.0	%)

Overall		29.7	%		29.8	%

		The Corporation’s effective income tax rate reflects the effect of 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, the domestic production deduction and the tax effect of nondeductibility of goodwill related to asset sales. 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 change in the year-to-date estimated overall effective income tax rate during the third quarter of 2007, when compared with the year-to-date estimated overall effective income tax rate as of June 30, 2007, is primarily due to discrete tax events. During the quarter ended September 30, 2007, discrete tax events, primarily the reversal of 2003 tax reserves for which the statute of limitations expired and the true-up of the 2006 provision estimates to actual as a result of filing the related tax returns during the period, reduced income tax expense and increased net earnings by $5,120,000, or $0.12 per diluted share.

		The change in the year-to-date estimated overall effective income tax rate during the third quarter of 2006, when compared with the year-to-date estimated overall effective income tax rate as of June 30, 2006, resulted primarily from discrete tax events. During the quarter ended September 30, 2006, discrete tax events, primarily consisting of the reversal of tax contingencies related to the expiration of the statute of limitations for the 2002 tax year, providing reserves for tax contingencies and the evaluation of deferred taxes, increased net earnings for the quarter ended September 30, 2006 by $2,679,000, or $0.06 per diluted share.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
Third Quarter and Nine Months Ended September 30, 2007

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 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 302 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 buildings. The Specialty Products segment produces magnesia-based chemicals products used in industrial, agricultural and environmental applications; dolomitic lime sold primarily to customers in the steel industry; and structural composite products.

CRITICAL ACCOUNTING POLICIES The Corporation outlined its critical accounting policies in its Annual Report on Form 10-K for the year ended December 31, 2006, filed with the Securities and Exchange Commission on February 28, 2007.

During the quarter ended September 30, 2007, the Corporation reviewed its inventory standards and recorded a $3.6 million increase in its finished goods inventory values for a year-to-date total of $12.6 million, inclusive of the $9.0 million increase recorded in the second quarter of 2007. The increase in the third quarter of 2007 continues the trend of the Corporation matching current inventory values with current cost of sales. Management will continue to update its inventory standards on a quarterly basis going forward. In prior years, the Corporation updated inventory standards once a year in the fourth quarter. During the fourth quarter of 2006, the Corporation recorded a $13.4 million increase to finished goods inventory values for the annual updating of inventory standards.

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.

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 nine months ended September 30, 2007 and 2006 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales (dollars in thousands):

Net sales for the Aggregates business for the 2007 third quarter were $509.7 million, a 3.7% increase over 2006 third-quarter sales of $491.5 million. Heritage aggregates pricing increased 8.6%, contributing to a 200-basis-point increase in the aggregates product line gross margin excluding freight and delivery revenues and a 290-basis-point improvement in consolidated operating margin excluding freight and delivery revenues. These record results were achieved despite a greater than 4% decline in aggregates volume and an increase in production costs resulting from operating leverage and inventory control. Pricing improvements continued to hold in the Aggregates business. As expected, the rate of growth in aggregates pricing slowed during the quarter in response to the effect of more limited 2007 mid-year price increases, which reflects reduced demand over the past six quarters. However, even with weaker demand, the rate of pricing improvement continues to be well above historic norms for the Aggregates business, which reflects the intrinsic value of well-located, zoned and permitted aggregates reserves.

While weather continued to affect performance in the West Group during the quarter, the Group finished the quarter with volumes up over 2% and showed significant earnings improvement over the prior-year period. July 2007 was the wettest July in recorded weather history in Texas and the historic rainfall affected both shipments and operations. However, as dry, hot days began to outnumber wet days in mid-August and September, volume for commercial and infrastructure projects began to return to normal levels. The Raleigh-Durham and Greensboro, North Carolina areas, as well as Virginia, had positive volume growth for the quarter. Volumes declined in most other regions of the country, reflecting the continued diminishment of residential construction coupled with a slowing in the rate of growth of commercial construction, notably office and retail space.

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. Furthermore, excessive rainfall can also jeopardize shipments, production and profitability. Because of the potentially significant impact of weather on the Corporation’s operations, third quarter and year-to-date results are not indicative of expected performance for other interim periods or the full year.

Third-quarter results for the Specialty Products segment, which includes magnesia chemicals, dolomitic lime and targeted activity in structural composites, were positive. Specialty Products’ net sales were $39.2 million for the third quarter 2007 compared with $35.9 million for the prior-year period. Earnings from operations for the quarter were $9.0 million compared with $5.1 million in the year-earlier period. Management has established specific quarterly benchmarks for the remainder of 2007 to evaluate the viability of the remaining components of the structural composites product line.

Selling, general and administrative expenses for the quarter ended September 30, 2007 was $36.4 million versus $35.3 million in the 2006 period. Selling, general and administrative expenses, as a percentage of net sales, declined slightly to 6.6%.

Among other items, other operating income and expenses, net, includes gains and losses on the sale of assets; gains and losses related to certain accounts receivable; rental, royalty and services income; and the accretion and depreciation expenses related to Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations. For the third quarter, consolidated other operating income and expenses, net, was income of $6.2 million in 2007 compared with $2.2 million in 2006, primarily as a result of a $4.5 million gain on the sale of land in 2007 for the West Group.

Consolidated interest expense was $17.2 million for the third quarter 2007 as compared with $10.1 million for the prior-year quarter. The increase primarily resulted from interest for the 6.25% Senior Notes and Floating Rate Senior Notes issued in April 2007 and higher outstanding commercial paper borrowings during the third quarter 2007.

In addition to other offsetting amounts, other nonoperating income and expenses, net, are comprised generally of interest income, net equity earnings from nonconsolidated investments and eliminations of minority interests for consolidated non-wholly owned subsidiaries. Consolidated other nonoperating income and expenses, net, for the quarter ended September 30, was income of $1.3 million in 2007 compared with expense of $0.2 million in 2006, primarily as a result of higher earnings on nonconsolidated investments in 2007.

Including acquisitions and divestitures, aggregates pricing for the nine months ended September 30, 2007 increased 12.0% and aggregates product line volume decreased 9.0%. Shipment volumes reflect a significant decline in the residential construction market and inclement weather experienced by the West Group.

For the nine months ended September 30, other operating income and expenses, net, was income of $11.5 million in 2007 compared with $9.4 million in 2006. The increase results primarily from higher gains on sales of assets, primarily excess land, and was partially offset by lower royalty and rental income.

Consolidated interest expense was $45.1 million for the nine months ended September 30, 2007 compared with $29.8 million for the prior-year period. The increase resulted from interest for the 6.25% Senior Notes issued in April 2007, Floating Rate Senior Notes issued in April 2007, increased outstanding commercial paper balances, and a lower amount of capitalized interest related to major plant expansion and efficiency projects in 2007 as compared with the prior-year period.

LIQUIDITY AND CAPITAL RESOURCES Net cash provided by operating activities during the nine months ended September 30, 2007 was $272.8 million compared with $209.7 million in the comparable period of 2006. Operating cash flow is generally from net earnings, before deducting depreciation, depletion and amortization, offset by working capital requirements. Net cash provided by operating activities for the first nine months of 2007 as compared with the year-earlier period reflects higher earnings before depreciation, depletion and amortization and higher accruals for income tax obligations, and was partially offset by a higher build up of inventories due to declining shipment volumes, increased cash paid for interest and increased tax benefits from stock option exercise activity.

Depreciation, depletion and amortization was as follows (dollars in millions):


	Nine Months Ended
	September 30,
	2007		2006
Depreciation	$	105.5	$	95.1
Depletion		3.4		4.6
Amortization		2.2		3.0

	$	111.1	$	102.7

The increase in depreciation expense is primarily due to the completion of several large capital projects, including new plants at the Three Rivers operation in Kentucky and North Troy operation in Oklahoma.

The seasonal nature of the construction aggregates business impacts quarterly operating cash flow when compared with the year. Full year 2006 net cash provided by operating activities was $338.2 million, compared with $209.7 million for the first nine months of 2006.

First nine months capital expenditures, exclusive of acquisitions, were $196.9 million in 2007 and $212.6 million in 2006. Capital expenditures during the first nine months of 2006 included work on several major plant expansion and efficiency projects. Comparable full-year capital expenditures were $266.0 million in 2006. Full-year capital spending is expected to approximate $260.0 million for 2007, including the Hunt Martin joint venture and exclusive of acquisitions, and is up from the previous estimate of $235 million due to the purchase of 50 new barges for $24 million which were originally expected to be financed through operating leases.

During the nine months of 2006, the Corporation received repayment of a $12.5 million note receivable related to the divestiture of its Houston asphalt operations. The Corporation continues to have a continuing financial interest in the Houston asphalt market via a supply agreement and therefore continues to include the divested locations in continuing operations.

During 2007, the Corporation continued its common stock repurchase plan 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 quarter ended September 30, 2007. During the nine months ended September 30, the Corporation repurchased 3,585,000 shares at an aggregate cost of $495.2 million in 2007 compared with 1,274,200 shares at an aggregate cost of $112.6 million in 2006. In August 2007, the Board of Directors authorized management to repurchase up to an additional 5.0 million shares of its common stock. At September 30, 2007, 5,646,000 shares of common stock were remaining under the Corporation’s repurchase authorization.

The Corporation refinanced its $125 million 6.9% Notes that matured in August 2007 with proceeds from the Corporation’s offering of public debt in April 2007 and issuances of commercial paper in the A-2/P-2 markets (see page 31 for a discussion of credit ratings). The tightening of the credit markets made placement of A-2/P-2 commercial paper more difficult during the August and September 2007 timeframe. The Corporation initially placed the commercial paper in the overnight markets and effectively termed the commercial paper to 30-day maturities over a period of one week. Since that time, placement has not been problematic.

In September 2006, the Corporation entered into two forward starting interest rate swap agreements (the “Swap Agreements”) related to $150 million of the Corporation’s anticipated refinancing of its $200 million 5.875% Notes due in 2008. The change in fair value of the Swap Agreements, net of income taxes, is recorded directly in shareholders’ equity as other comprehensive earnings/loss. At September 30, 2007, the fair value of the Swap Agreements was a liability of $1.0 million and was included in other noncurrent liabilities in the Corporation’s consolidated balance sheet. Other comprehensive earnings/loss for the nine months ended September 30, 2007 included a gain of $0.6 million, net of tax, for the change in fair value of the Swap Agreements.

On April 17, 2007, the Corporation entered into an amendment of its $250 million five-year revolving credit agreement, which modified the leverage ratio covenant in the agreement. As modified, 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 2.75 to 1.00 as of the end of any fiscal quarter. Furthermore, the covenant allows the Ratio to exclude debt incurred in connection with an acquisition for a period of 180 days, provided that the Ratio does not exceed 3.25 to 1.00. 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 September 30, 2007, the Corporation’s ratio of consolidated debt to consolidated EBITDA, as defined, for the trailing twelve month EBITDA was 1.86 and was calculated as follows:


	Twelve Month Period
	October 1, 2006 to
	September 30, 2007

Earnings from continuing operations	$	267,828

Consolidated debt at September 30, 2007	$	1,128,774

Consolidated debt to consolidated EBITDA, as defined, at September 30, 2007 for the trailing twelve month EBITDA		1.86

On April 25, 2007, the Corporation issued $250 million of 6.25% Senior Notes due in 2037 and $225 million of Floating Rate Senior Notes due in 2010 (collectively, the “Senior Notes”). The 6.25% Senior Notes may be redeemed in whole or in part prior to their maturity at a “make whole” redemption price. The Floating Rate Senior Notes bear interest at a rate equal to the three-month LIBOR plus 0.15% and may not be redeemed prior to maturity. Upon a change of control repurchase event, the Corporation will be required to make an offer to repurchase all outstanding Senior Notes at a price in cash equal to 101% of the principal amount of the Senior Notes, plus any accrued and unpaid interest to, but not including, the purchase date.

The management team and Board of Directors have focused on establishing prudent leverage targets that provide for value creation through strong operational performance, continued investment in internal growth opportunities, financial flexibility to support opportunistic and strategic acquisitions and a return of cash to shareholders through sustainable dividends and share repurchase programs while maintaining a solid investment grade rating. Given these parameters, in the ordinary course of business and absent any future debt incurred in connection with an acquisition, the Corporation expects to manage its leverage within a range of 2.0 to 2.5 times consolidated debt to consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined by the underlying credit agreement.

Based on prior performance and current expectations, the Corporation’s management believes that cash flows from internally generated funds and its access to capital markets are expected to continue to be sufficient to provide the capital resources necessary to fund the operating needs of its existing businesses, cover debt service requirements, and allow for payment of dividends. However, the Corporation is exposed to risk from tightening credit markets, through the interest cost related to its $225 million Floating Rate Senior Notes due in 2010 and the availability and interest cost related to its commercial paper program which is rated A-2 by Standard and Poor’s and P-2 by Moody’s. Commercial paper of $76 million was outstanding at September 30, 2007. Refer also to “Risk to Earnings Expectations” disclosed in the Corporation’s third-quarter results press release dated October 30, 2007.

The Corporation may be required to obtain additional levels of financing in order to fund certain strategic acquisitions, if any such opportunities arise. Currently, the Corporation’s senior unsecured debt is rated BBB+ by Standard & Poor’s and Baa1 by Moody’s. The Corporation’s commercial paper obligations are rated A-2 by Standard & Poor’s and P-2 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.

Contractual Obligations

At September 30, 2007, the Corporation had gross unrecognized tax benefits, excluding interest, of $29.4 million. The Corporation anticipates settlement of $19.4 million with the taxing authorities in the upcoming twelve months and settlement of $10.0 million in one to three years.

ACCOUNTING CHANGES As discussed in Note 1 to the Consolidated Financial Statements, effective January 1, 2007, the Corporation adopted FIN 48 and reduced retained earnings by $1.4 million.

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, 2006, filed with the Securities and Exchange Commission on February 28, 2007. Management continues to evaluate its exposure to all operating risks on an ongoing basis.

In July 2007, the state of North Carolina approved the issuance of $300 million of Grant Anticipation Revenue vehicles, or GARVEE bonds, to fund various road projects statewide. The bonds will be repaid with federal money the state expects to receive for highway and interstate projects in future years. Management currently expects construction to begin on these projects in 2008.

OUTLOOK 2007 Based upon the Corporation’s strong year-to-date performance, management continues to have a positive outlook for the remainder of the year. Aggregates product line pricing is expected to increase in the upper half of single digits for the fourth quarter and 10% to 11% for the year; however, aggregates shipments are becoming more difficult to estimate. Management currently expects aggregates volume to decrease 2% to 4% in the fourth quarter and decrease 6% to 8% for the year with the degree of decline predicated on continued correction in the residential construction market, in addition to slower growth in commercial construction. Management believes certain commercial construction, notably office and retail space, is exhibiting a cautionary pause in activity in some areas as developers digest the impact of the current credit markets on construction and development plans. Capacity-related, industrial and distribution-related construction remains in a solid growth pattern. Infrastructure spending is expected to remain positive, although rising construction and materials prices have made projects more costly.

The Specialty Products segment, which includes magnesia chemicals, dolomitic lime and focused activity in structural composites, is expected to contribute $31 million to $33 million in pretax earnings in 2007 compared with $22 million in 2006. Management expects the magnesia chemicals business to continue to grow and demand for dolomitic lime from the steel industry to be down slightly.

With this backdrop, management currently expects net earnings per diluted share for the fourth quarter to range from $1.37 to $1.72 and the range for the year is $6.10 to $6.45.

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

Investors are cautioned that all statements in this Quarterly Report that relate to the future involve risks and uncertainties, and are based on assumptions that the Corporation believes in good faith are reasonable but which may be materially different from actual results. Forward-looking statements give the investor our expectations or forecasts of future events. You can identify these statements by the fact that they do not relate only to historical or current facts. They may use words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” and other words of similar meaning in connection with future events or future operating or financial performance. Any or all of our forward-looking statements here and in other publications may turn out to be wrong.

RESULTS OF OPERATIONS
Third Quarter and Nine Months Ended September 30, 2007
(Continued)

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 level and timing of federal and state transportation funding, particularly in North Carolina, one of the Corporation’s largest and most profitable states, and Texas and South Carolina, which when coupled with North Carolina, represented 44% of 2006 net sales in the Aggregates business; levels of commercial construction spending in the markets the Corporation serves; the severity of a continued decline in the residential construction market and the slowing growth rate in commercial construction, notably office and retail space; unfavorable weather conditions, particularly Atlantic Ocean hurricane activity and the early onset of winter; the volatility of fuel costs; continued increases in the cost of 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 and Gulf Coast markets; increased transportation costs, including increases from higher passed-through energy costs and higher volumes of rail and water shipments; continued strength in the steel industry markets served by the Corporation’s dolomitic lime products; successful development and implementation of the structural composite technological process, commercialization of strategic products for specific market segments, and the generation of earnings streams sufficient enough to support the recorded assets of the structural composites product line; 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 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. Since June 30, 2004, the Federal Reserve Board has increased the federal funds rate from 1.00% to 4.75% at September 30, 2007. This increase has negatively affected the residential construction market, which accounted for approximately 17% of the Corporation’s aggregates product line shipments in 2006. 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 its temporary cash investments, including money market funds and overnight investments in Eurodollars; any outstanding commercial paper obligations; Floating Rate Senior Notes; defined benefit pension plans; and energy costs. Additionally, the shareholders’ equity of the Corporation is affected by changes in the fair value of forward starting interest rate swap agreements.

Commercial Paper Obligations. The Corporation has a $250 million commercial paper program in which borrowings bear interest at a variable rate based on LIBOR. At September 30, 2007, commercial paper borrowings of $76 million were outstanding. As commercial paper borrowings bear interest at a variable rate, the Corporation has interest rate risk. The effect of a hypothetical 100 basis point increase in interest rates on commercial paper borrowings of $76 million would increase interest expense by $0.8 million on an annual basis.

Floating Rate Senior Notes. The Corporation has $225 million of Floating Rate Senior Notes that bear interest at a rate equal to the three-month LIBOR plus 0.15%. As the Floating Rate Senior Notes bear interest at a variable rate, the Corporation has interest rate risk. The effect of a hypothetical 100 basis point increase in interest rates on borrowings of $225 million would increase interest expense by $2.3 million on an annual basis.

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, 2006, filed with the Securities and Exchange Commission on February 28, 2007.

Energy Costs. Energy costs, including diesel fuel and natural gas, represent significant production costs for the Corporation. Increases in these costs generally are tied to energy sector inflation. In 2006, energy costs increased significantly, with fuel price increases lowering earnings per diluted share by $0.36. A hypothetical 10% change in the Corporation’s energy prices in 2007 as compared with 2006, assuming constant volumes, would impact 2007 pretax earnings by approximately $17.8 million.

Page 35 of 40

MARTIN MARIETTA MATERIALS, INC. AND CONSOLIDATED SUBSIDIARIES
FORM 10-Q
For the Quarter Ended September 30, 2007

Aggregate Risk for Interest Rates and Energy Sector Inflation. The pension expense for 2007 is calculated based on assumptions selected at December 31, 2006. Therefore, interest rate risk in 2007 is limited to the potential effect related to outstanding commercial paper and the Corporation’s Floating Rate Senior Notes. Assuming outstanding commercial paper of $76 million and Floating Rate Senior Notes of $225 million, the impact of a hypothetical 100 basis point increase in interest rates would increase interest expense and decrease pretax earnings by $3.0 million. Additionally, a 10% change in energy costs would impact annual pretax earnings by $17.8 million.

Forward Starting Interest Rate Swap Agreements. In September 2006, the Corporation entered into forward starting interest rate swap agreements (the “Swap Agreements”) for the anticipated refinancing of $150.0 million of its $200.0 million 5.875% Notes due in 2008. In accordance with Statement of Financial Accounting Standards No. 133 Accounting for Derivative Instruments and Hedging Activities (“FAS 133”), the fair values of the Swap Agreements are recorded as an asset or liability in the consolidated balance sheet. The change in fair value is recorded directly in shareholders’ equity, net of taxes, as other comprehensive earnings/loss. At September 30, 2007, the fair value of the Swap Agreements was a liability of $1.0 million and was included in other noncurrent liabilities in the Corporation’s consolidated balance sheet.

As a result of the Swap Agreements, the Corporation’s comprehensive earnings/loss will be affected by changes in the LIBOR rate. A hypothetical change in interest rates of 100 basis points would change other comprehensive earnings/loss by approximately $5.7 million, which is net of taxes of $3.7 million.

Item 4. Controls and Procedures

As of September 30, 2007, 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 September 30, 2007. There have been no significant changes in the Corporation’s internal controls or in other factors that could significantly affect the internal controls subsequent to September 30, 2007.
