PART I

ITEM 1. BUSINESS

General

     Martin Marietta Materials, Inc. (the “Company”) is a leading producer of aggregates for the construction industry, including infrastructure, commercial, agricultural, and residential. The Company also has a Specialty Products segment that manufactures and markets magnesia-based chemical products used in industrial, agricultural, and environmental applications; dolomitic lime sold primarily to the steel industry; and structural composite products. In 2007, the Company’s Aggregates business accounted for 92% of the Company’s total net sales, and the Company’s Specialty Products segment accounted for 8% of the Company’s total net sales.

     The Company was formed in 1993 as a North Carolina corporation to serve as successor to the operations of the materials group of the organization that is now Lockheed Martin Corporation. An initial public offering of a portion of the Company’s Common Stock was completed in 1994, followed by a tax-free exchange transaction in 1996 that resulted in 100% of the Company’s Common Stock being publicly traded.

     Initially, the Company’s aggregates operations were predominantly in the Southeast, with additional operations in the Midwest. In 1995, the Company started its geographic expansion with the purchase of an aggregates business that included an extensive waterborne distribution system along the East and Gulf Coasts and the Mississippi River. Smaller acquisitions that year, including the acquisition of the Company’s granite operations on the Strait of Canso in Nova Scotia, complemented the Company’s new coastal distribution network.

     Subsequent acquisitions in 1997 and 1998 expanded the Company’s Aggregates business in the middle of the country and added a leading producer of aggregates products in Texas, which provided the Company with access to an extensive rail network in Texas. These two transactions positioned the Company for numerous additional expansion acquisitions in Ohio, Indiana, and the southwestern regions of the United States, with the Company completing 29 smaller acquisitions between 1997 and 1999, which allowed the Company to enhance and expand its presence in the aggregates marketplace.

     In 1998, the Company made an initial investment in an aggregates business that would later serve as the Company’s platform for further expansion in the southwestern and western United States. In 2001, the Company completed the purchase of all of the remaining interests of this business, which increased its ability to use rail as a mode of transportation.

     Effective January 1, 2005, the Company formed a joint venture with Hunt Midwest Enterprises to operate substantially all of the aggregates facilities of both companies in Kansas City and surrounding areas. The joint venture was formed by the parties contributing a total of 15 active quarry operations with production of approximately 7.5 million tons annually.

3

     Between 2001 and 2007, the Company disposed of or permanently shut down a number of underperforming operations, including aggregates, asphalt, ready mixed concrete, trucking, and road paving operations of its Aggregates business and the refractories business of its Magnesia Specialties business. In some of its divestitures, the Company concurrently entered into supply agreements to provide aggregates at market rates to certain of these divested businesses. The Company will continue to evaluate opportunities to divest underperforming assets during 2008 in an effort to redeploy capital for other opportunities.

Business Segment Information

     The Company operates in four reportable business segments: the Mideast Group, Southeast Group, and West Group, collectively the Aggregates business, and the Specialty Products segment. The Specialty Products segment includes the magnesia-based chemicals and dolomitic lime businesses and the structural composites product line. Information concerning the Company’s total revenues, net sales, earnings from operations, assets employed, and certain additional information attributable to each reportable business segment for each year in the three-year period ended December 31, 2007 is included in “Note O: Business Segments” of the “Notes to Financial Statements” of the Company’s 2007 consolidated financial statements (the “2007 Financial Statements”), which are included under Item 8 of this Form 10-K, and are part of the Company’s 2007 Annual Report to Shareholders (the “2007 Annual Report”), which information is incorporated herein by reference.

Aggregates Business

     The Aggregates business mines, processes and sells granite, limestone, sand, gravel, and other aggregate products for use in all sectors of the public infrastructure, commercial and residential construction industries as well as miscellaneous uses such as agriculture, railroad ballast and chemical uses. The Aggregates business also includes the operation of other construction materials businesses. These businesses, located primarily in the West Group, were acquired through continued selective vertical integration by the Company, and include asphalt, ready mixed concrete, and road paving operations.

     The Company is a leading producer of aggregates for the construction industry in the United States. In 2007, the Company’s Aggregates business shipped 182.3 million tons of aggregates primarily to customers in 31 states, Canada, the Bahamas, and the Caribbean Islands, generating net sales and earnings from operations of $1.8 billion and $431.8 million, respectively.

     The Aggregates business markets its products primarily to the construction industry, with approximately 48% of its shipments made to contractors in connection with highway and other public infrastructure projects and the balance of its shipments made primarily to contractors in connection with commercial and residential construction projects. As a result of dependence upon the construction industry, the profitability of aggregates producers is sensitive to national, regional, and local economic conditions, and particularly to cyclical swings in construction spending, which is affected by fluctuations in interest rates, demographic and population shifts, and changes in the level of infrastructure spending funded by the public sector. The Company’s Aggregates business covers a wide geographic area, with aggregates, asphalt products, and ready mixed concrete sold and shipped from a network of approximately 287 quarries, underground mines, distribution facilities, and plants in 28 states, Canada, and the Bahamas. The Company’s five largest revenue-generating states (North

4

Carolina, Texas, Georgia, Iowa, and South Carolina) account for approximately 61% of total 2007 net sales for the Aggregates business by state of destination. The Company’s Aggregates business is accordingly affected by the economies in these regions and has been adversely affected in part by recessions and weaknesses in these economies from time to time.

     The Company’s Aggregates business is also highly seasonal, due primarily to the effect of weather conditions on construction activity within its markets. The operations of the Aggregates business that are concentrated in the northern United States and Canada typically experience more severe winter weather conditions than operations in the southeastern and southwestern regions of the United States. Excessive rainfall can also jeopardize shipments, production, and profitability. Due to these factors, the Company’s second and third quarters are the strongest, with the first quarter generally reflecting the weakest results. Results in any quarter are not necessarily indicative of the Company’s annual results. Similarly, the operations of the Aggregates business in the southeastern and Gulf Coast regions of the United States and the Bahamas are at risk for hurricane activity and have experienced weather-related losses in recent years. The Company did not incur significant damage from hurricanes during 2007. However, during 2007, the West Group, particularly Texas, southern Oklahoma and Kansas, experienced near historic levels of rainfall and flooding, which affected both shipments and operations.

     Natural aggregates sources can be found in relatively homogeneous deposits in certain areas of the United States. As a general rule, truck shipments from an individual quarry are limited because the cost of transporting processed aggregates to customers is high in relation to the price of the product itself. As described below, the Company’s distribution system mainly uses trucks, but also has access to a river barge and ocean vessel network where the per mile unit cost of transporting aggregates is much lower. In addition, acquisitions have enabled the Company to extend its customer base through increased access to rail transportation. Proximity of quarry facilities to customers or to long-haul transportation corridors is an important factor in competition for aggregates business.

     A growing percentage of the Company’s aggregates shipments are being moved by rail or water through a distribution yard network. In 1994, 93% of the Company’s aggregates shipments were moved by truck, the rest by rail. In contrast, in 2007, the originating mode of transportation for the Company’s aggregates shipments was 74% by truck, 17% by rail, and 9% by water. The majority of the rail and water movements occur in the Southeast Group and the West Group. The Company has an extensive network of aggregates quarries and distribution centers along the Mississippi River system throughout the central and southern United States and in the Bahamas and Canada, as well as distribution centers along the Gulf of Mexico and Atlantic coasts. In recent years, the Company has brought additional capacity on line at its Bahamas and Nova Scotia locations to transport materials via oceangoing ship. Further, in 2006, the Company completed the second largest capital project in its history, a highly-automated plant and barge loadout system at its Three Rivers facility in Kentucky. This new plant, a key site in the Company’s long-haul distribution network, is capable of producing more than 8 million tons per year for shipment to 14 states along the Ohio and Mississippi River network. The Company is currently focusing a significant part of its capital spending program on locations along the geological fall line in Georgia and South Carolina, which are part of the rail transportation network.

     In addition, the Company’s acquisitions and capital projects have expanded its ability to ship material by rail, as discussed in more detail below. The Company has added additional capacity in a

5

number of locations that can now accommodate larger unit train movements. These expansion projects have enhanced the Company’s long-haul distribution network. The Company’s process improvement program has also improved operational effectiveness through plant automation, mobile fleet modernization, right-sizing, and other cost control improvements. Accordingly, the Company has enhanced its reach through its ability to provide cost-effective coverage of coastal markets on the east and gulf coasts, as well as geographic areas that can be accessed economically by the Company’s expanded distribution system. This distribution network moves aggregates materials from domestic and offshore sources, via rail and water, to markets where aggregates supply is limited.

     As the Company continues to move more aggregates by rail and water, embedded freight costs have consequently reduced gross margins. This typically occurs where the Company transports aggregates from a production location to a distribution location by rail or water, and the customer pays a selling price that includes a freight component. Margins are negatively affected because the Company typically does not charge the customer a profit associated with the transportation component of the selling price. Moreover, the Company’s expansion of its rail-based distribution network, coupled with the extensive use of rail service in the Southeast and West Groups, increase the Company’s dependence on and exposure to railroad performance, including track congestion, crew availability, and power availability, and the ability to renegotiate favorable railroad shipping contracts. The waterborne distribution network, primarily located within the Southeast Group, also increases the Company’s exposure to certain risks, including the ability to negotiate favorable shipping contracts, demurrage costs, fuel costs, barge or ship availability, and weather disruptions. The Company has entered into long-term agreements with shipping companies to provide ships to transport the Company’s aggregates to various coastal ports.

     In 2005 and 2006, the Company experienced rail transportation shortages in Texas and parts of the Southeast Group. These shortages were caused by the downsizing in personnel and equipment by certain railroads during the economic downturn in the early part of this decade. Further, in response to these issues, rail transportation providers focused on increasing the number of cars per unit train under transportation contracts and are generally requiring customers, through the freight rate structure, to accommodate larger unit train movements. A unit train is a freight train moving large tonnages of a single bulk product between two points without intermediate yarding and switching. In 2006, the Company brought a new plant online on a greensite at its North Troy operation in Oklahoma, which is capable of producing 5 million tons per year and handling multiple 90-car unit trains. Certain of the Company’s sales yards in the southwestern region of the United States have the system capabilities to meet the unit train requirements. Over the last few years, the Company has made capital improvements to a number of its sales yards in this region in order to better accommodate unit train unloadings. Further, in 2005, the Company addressed certain of its railcar needs for future shipments by leasing 780 railcars under two master lease agreements.

     The Company experiences shortages of barges from time to time. Barge availability has become an issue as the rate of barges being retired is exceeding the rate at which new barges are being constructed. Shipyards that build barges are operating at capacity, and the lead time for new barges is approximately 18 months. To help alleviate this problem, the Company purchased 50 new barges in 2007.

     The Company’s management expects the multiple transportation modes that have been developed with various rail carriers and via barges and deepwater ships should provide the Company

6

with the flexibility to effectively serve customers in the southeastern and southwestern regions of the United States.

     The construction aggregates industry has been in a consolidating mode. The Company’s management expects this trend to continue but at a slower rate as the number of suitable small to mid-sized acquisition targets in high growth markets decline. The Company’s Board of Directors and management continue to review and monitor the Company’s strategic long-term plans, which include assessing business combinations and arrangements with other companies engaged in similar businesses, increasing market share in the Company’s core businesses, and pursuing new opportunities related to the Company’s existing markets.

     The Company became more vertically integrated with an acquisition in 1998 and subsequent acquisitions, particularly in the West Group, pursuant to which the Company acquired asphalt, ready mixed concrete, paving construction, trucking, and other businesses, which complement the Company’s aggregates business. These vertically integrated operations accounted for approximately 6% of revenues of the Aggregates business in 2007. These operations have lower gross margins than aggregates products, and are affected by volatile factors, including fuel costs, operating efficiencies, and weather, to an even greater extent than the Company’s aggregates operations. The road paving and trucking businesses were acquired as supplemental operations that were part of larger acquisitions. As such, they do not represent core businesses of the Company. The results of these operations are currently insignificant to the Company as a whole. Over the last few years the Company has disposed of some of these operations. The Company continues to review carefully the acquired vertically integrated operations to determine if they represent opportunities to divest underperforming assets in an effort to redeploy capital for other opportunities.

     Environmental and zoning regulations have made it increasingly difficult for the aggregates industry to expand existing quarries and to develop new quarry operations. Although it cannot be predicted what policies will be adopted in the future by federal, state, and local governmental bodies regarding these matters, the Company anticipates that future restrictions will likely make zoning and permitting more difficult, thereby potentially enhancing the value of the Company’s existing mineral reserves.

     Management believes the Aggregates business’ raw materials, or aggregates reserves, are sufficient to permit production at present operational levels for the foreseeable future. The Company does not anticipate any material difficulty in obtaining the raw materials that it uses for current production in its Aggregates business. The Company’s aggregates reserves on the average exceed 50 years of production, based on current levels of activity. However, certain locations may be subject to more limited reserves and may not be able to expand. Moreover, as noted above, environmental and zoning regulations will likely make it harder for the Company to expand its existing quarries or develop new quarry operations. The Company generally sells products in its Aggregates business upon receipt of orders or requests from customers. Accordingly, there is no significant order backlog. The Company generally maintains inventories of aggregate products in sufficient quantities to meet the requirements of customers.

     Less than 2% of the revenues from the Aggregates business are from foreign jurisdictions, principally Canada and the Bahamas, with revenues from customers in foreign countries totaling $22.3 million, $25.0 million, and $16.4 million during 2007, 2006, and 2005, respectively.

Specialty Products Business

     The Company manufactures and markets, through its Specialty Products business, magnesia-based chemical products for industrial, agricultural, and environmental applications, and dolomitic lime for use primarily in the steel industry. These chemical products have varying uses, including flame retardants, wastewater treatment, pulp and paper production, and other environmental applications. In 2007, 66% of Specialty Products’ net sales were attributable to chemical products, 29% to lime, and 2% to stone, with the remaining 3% attributable to the structural composite products line described below.

     Given the high fixed costs associated with operating this business, low capacity utilization negatively affects its results of operations. A significant portion of the costs related to the production of magnesia-based products and dolomitic lime is of a fixed or semi-fixed nature. In addition, the production of certain magnesia chemical products and lime products requires natural gas, coal, and petroleum coke to fuel kilns. Price fluctuations of these fuels affect the profitability of this business.

     In 2007, approximately 75% of the lime produced was sold to third-party customers, while the remaining 25% was used internally as a raw material in making the business’ chemical products. Dolomitic lime products sold to external customers are used primarily by the steel industry. Accordingly, a portion of the profitability of the Specialty Products business is dependent on steel production capacity utilization and the related marketplace. Products used in the steel industry accounted for approximately 70% of the Specialty Products’ net sales in 2007, attributable primarily to the sale of dolomitic lime products. During 2007, softness in housing-related steel products and auto making curtailed demand for steel making. Further, steel production in 2007 was reduced following a record year for steel imports in 2006. Import rates in 2007 adjusted to the domestic market, but the continued downturn in steel-related industries will affect Specialty Products’ revenues.

     Management has shifted the strategic focus of this magnesia-based business to specialty chemicals that can be produced at volume levels that support efficient operations. Accordingly, that business is not as dependent on the steel industry as is the dolomitic lime portion of the Specialty Products business.

     The principal raw materials used in the Specialty Products business are dolomitic limestone and alkali-rich brine. Management believes that its reserves of dolomitic limestone and brine are sufficient to permit production at the current operational levels for the foreseeable future.

     After the brine is used in the production process, the Specialty Products business must dispose of the processed brine. In the past, the business did this by reinjecting the processed brine back into its underground brine reserve network around its facility in Manistee, Michigan. The business has also sold a portion of this processed brine to third parties. In 2003, Specialty Products entered into a long-term processed brine supply agreement with The Dow Chemical Company (“Dow”) pursuant to which Dow purchases processed brine from Specialty Products, at market rates, for use in Dow’s production of calcium chloride products. Specialty Products also entered into a venture with Dow to construct, own, and operate a processed brine supply pipeline between the Specialty Products facility in Manistee, Michigan, and Dow’s facility in Ludington, Michigan. Construction of the pipeline was

8

completed in 2003, and Dow began purchasing processed brine from Specialty Products through the pipeline.

     Specialty Products generally delivers its products upon receipt of orders or requests from customers. Accordingly, there is no significant order backlog. Inventory for products is generally maintained in sufficient quantities to meet rapid delivery requirements of customers.

     Approximately 12% of the revenues of the Specialty Products business are from foreign jurisdictions, principally Canada, Mexico, Europe, South America, and the Pacific Rim, but no single country accounts for 10% or more of the revenues of the business. Revenues from customers in foreign countries totaled $20.2 million, $17.0 million, and $19.6 million in 2007, 2006, and 2005, respectively. As a result of these foreign market sales, the financial results of the Specialty Products business could be affected by foreign currency exchange rates or weak economic conditions in the foreign markets. To mitigate the short-term effects of currency exchange rates, the Specialty Products business principally uses the U.S. dollar as the functional currency in foreign transactions.

     The Company also develops structural composite products, through its Specialty Products business and its wholly-owned subsidiary, Martin Marietta Composites (“MMC”). Pursuant to various agreements, MMC has rights to commercialize certain proprietary technologies including those related to flat panel applications. These agreements give MMC the opportunity to pursue the use of certain fiber-reinforced polymer composites technologies for products where corrosion resistance and high strength-to-weight ratios are important factors. MMC continued its commercialization during 2007 of these structural composites technologies and initiated other selected products in related target markets.

     In 2007, MMC narrowed the focus within several market sectors for its composite products: military products, including ballistic and blast panels, transportation products, including rail cars, and other structural panel products. MMC will continue to evaluate a variety of homeland security and commercial uses for composite materials. There can be no assurance that these technologies will become profitable.

Patents and Trademarks

     As of February 15, 2008, the Company owns, has the right to use, or has pending applications for approximately 129 patents pending or granted by the United States and various countries and approximately 59 trademarks related to business. The Company believes that its rights under its existing patents, patent applications, and trademarks are of value to its operations, but no one patent or trademark or group of patents or trademarks is material to the conduct of the Company’s business as a whole.

Customers

     No material part of the business of any segment of the Company is dependent upon a single customer or upon a few customers, the loss of any one of which would have a material adverse effect on the segment. The Company’s products are sold principally to commercial customers in private industry. Although large amounts of construction materials are used in public works projects,

9

relatively insignificant sales are made directly to federal, state, county, or municipal governments, or agencies thereof.

Competition

     Because of the impact of transportation costs on the aggregates industry, competition in the Aggregates business tends to be limited to producers in proximity to each of the Company’s production facilities. Although all of the Company’s locations experience competition, the Company believes that it is generally a leading producer in the areas it serves. Competition is based primarily on quarry or distribution location and price, but quality of aggregates and level of customer service are also factors.

     There are over 3,800 companies in the United States that produce aggregates. The largest five producers account for approximately 31% of the total market. The Company, in its Aggregates business, competes with a number of other large and small producers. The Company believes that its ability to transport materials by ocean vessels, river barges, and rail have enhanced the Company’s ability to compete in the aggregates business. Some of the Company’s competitors in the aggregates industry have greater financial resources than the Company.

     The Company’s Specialty Products segment competes with various companies in different geographic and product areas principally on the basis of quality, price, technological advances, and technical support for its products. The Specialty Products business also competes for sales to customers located outside the United States, with revenues from foreign jurisdictions accounting for approximately 12% of revenues for the Specialty Products business in 2007, principally in Canada, Mexico, Europe, South America, and the Pacific Rim. Certain of the Company’s competitors in the Specialty Products business have greater financial resources than the Company.

Research and Development

     The Company conducts research and development activities principally for its magnesia-based chemicals business, at its plant in Manistee, Michigan, and for its structural composites product line, at its headquarters in Raleigh, North Carolina, and its plant in Sparta, North Carolina. In general, the Company’s research and development efforts in 2007 were directed to applied technological development for the use of its chemicals products and for its proprietary technologies, including composite materials. The Company spent approximately $0.9 million in 2007, $0.7 million in 2006, and $0.7 million in 2005 on research and development activities.

Environmental and Governmental Regulations

     The Company’s operations are subject to and affected by federal, state, and local laws and regulations relating to the environment, health and safety, and other regulatory matters. Certain of the Company’s operations may from time to time involve the use of substances that are classified as toxic or hazardous substances within the meaning of these laws and regulations. Environmental operating permits are, or may be, required for certain of the Company’s operations, and such permits are subject to modification, renewal, and revocation.

10

     The Company records an accrual for environmental remediation liabilities in the period in which it is probable that a liability has been incurred and the amounts can be reasonably estimated. Such accruals are adjusted as further information develops or circumstances change. The accruals are not discounted to their present value or offset for potential insurance or other claims or potential gains from future alternative uses for a site.

     The Company regularly monitors and reviews its operations, procedures, and policies for compliance with existing laws and regulations, changes in interpretations of existing laws and enforcement policies, new laws that are adopted, and new laws that the Company anticipates will be adopted that could affect its operations. The Company has a full time staff of environmental engineers and managers that perform these responsibilities. The direct costs of ongoing environmental compliance were approximately $9.1 million in 2007 and approximately $8.5 million in 2006 and are related to the Company’s environmental staff and ongoing monitoring costs for various matters (including those matters disclosed in this Annual Report on Form 10-K). Capitalized costs related to environmental control facilities were approximately $4.1 million in 2007 and are expected to be approximately $3 million in each of 2008 and 2009. The Company’s capital expenditures for environmental matters were not material to its results of operations or financial condition in 2007 and 2006. However, our expenditures for environmental matters generally have increased over time and are likely to increase in the future. Despite our compliance efforts, risk of environmental liability is inherent in the operation of the Company’s businesses, as it is with other companies engaged in similar businesses, and there can be no assurance that environmental liabilities will not have a material adverse effect on the Company in the future.

     Many of the requirements of the environmental laws are satisfied by procedures that the Company adopts as best business practices in the ordinary course of its operations. For example, plant equipment that is used to crush aggregates products may, as an ordinary course of operations, have an attached water spray bar that is used to clean the stone. The water spray bar also suffices as a dust control mechanism that complies with applicable environmental laws. The Company does not break out the portion of the cost, depreciation, and other financial information relating to the water spray bar that is only attributable to environmental purposes, as it would be derived from an arbitrary allocation methodology. The incremental portion of such operating costs that is attributable to environmental compliance rather than best operating practices is impractical to quantify. Accordingly, the Company expenses costs in that category when incurred as operating expenses.

     The environmental accruals recorded by the Company are based on internal studies of the required remediation costs and estimates of potential costs that arise from time to time under federal, state, and/or local environmental protection laws. Many of these laws and the regulations promulgated under them are complex, and are subject to challenges and new interpretations by regulators and the courts from time to time. In addition, new laws are adopted from time to time. It is often difficult to accurately and fully quantify the costs to comply with new rules until it is determined the type of operations to which they will apply and the manner in which they will be implemented is more accurately defined. This process often takes years to finalize and changes significantly from the time the rules are proposed to the time they are final. The Company typically has several appropriate alternatives available to satisfy compliance requirements, which could range from nominal costs to some alternatives that may be satisfied in conjunction with equipment replacement or expansion that also benefits operating efficiencies or capacities and carry significantly higher costs.

     Management believes that its current accrual for environmental costs is reasonable, although those amounts may increase or decrease depending on the impact of applicable rules as they are finalized from time to time and changes in facts and circumstances. The Company believes that any additional costs for ongoing environmental compliance would not have a material adverse effect on the Company’s obligations or financial condition.

     With respect to reclamation costs effective January 1, 2003, the Company adopted Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations (“FAS 143”). See “Note N: Commitments and Contingencies” of the “Notes to Financial Statements” of the 2007 Financial Statements and the 2007 Annual Report. Under FAS 143, future reclamation costs are estimated using statutory reclamation requirements and management’s experience and knowledge in the industry, and are discounted to their present value using a credit-adjusted, risk-free rate of interest. The future reclamation costs are not offset by potential recoveries. The Company is generally required by state or local laws or pursuant to the terms of an applicable lease to reclaim quarry sites after use. The Company performs activities on an ongoing basis that may reduce the ultimate reclamation obligation. These activities are performed as an integral part of the normal quarrying process. For example, the perimeter and interior walls of an open pit quarry are sloped and benched as they are developed to prevent erosion and provide stabilization. This sloping and benching meets dual objectives — safety regulations required by the Mine Safety and Health Administration for ongoing operations and final reclamation requirements. Therefore, these types of activities are included in normal operating costs and are not a part of the asset retirement obligation. Historically, the Company has not incurred substantial reclamation costs in connection with the closing of quarries. Reclaimed quarry sites owned by the Company are available for sale, typically for commercial development or use as reservoirs.

     The Company believes that its operations and facilities, both owned or leased, are in substantial compliance with applicable laws and regulations and that any noncompliance is not likely to have a material adverse effect on the Company’s operations or financial condition. See “Legal Proceedings” under Item 3 of this Form 10-K, “Note N: Commitments and Contingencies” of the “Notes to Financial Statements” of the 2007 Financial Statements included under Item 8 of this Form 10-K and the 2007 Annual Report, and “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Environmental Regulation and Litigation” included under Item 7 of this Form 10-K and the 2007 Annual Report. However, future events, such as changes in or modified interpretations of existing laws and regulations or enforcement policies, or further investigation or evaluation of the potential health hazards of certain products or business activities, may give rise to additional compliance and other costs that could have a material adverse effect on the Company.

     In general, quarry and mining facilities must comply with air quality, water quality, and noise regulations, zoning and special use permitting requirements, applicable mining regulations, and federal health and safety requirements. As new quarry and mining sites are located and acquired, the Company works closely with local authorities during the zoning and permitting processes to design new quarries and mines in such a way as to minimize disturbances. The Company frequently acquires large tracts of land so that quarry, mine, and production facilities can be situated substantial distances from surrounding property owners. Also, in certain markets the Company’s ability to transport material by rail and ship allows it to locate its facilities further away from residential areas. The Company has established policies designed to minimize disturbances to surrounding property owners from its operations.

     As is the case with other companies in the same industry, some of the Company’s products contain varying amounts of crystalline silica, a common mineral also known as quartz. Excessive, prolonged inhalation of very small-sized particles of crystalline silica has been associated with lung diseases, including silicosis, and several scientific organizations and some states, such as California, have reported that crystalline silica can cause lung cancer. The Mine Safety and Health Administration and the Occupational Safety and Health Administration have established occupational thresholds for crystalline silica exposure as respirable dust. The Company monitors occupational exposures at its facilities and implements dust control procedures and/or makes available appropriate respiratory protective equipment to maintain the occupational exposures at or below the appropriate levels. The Company, through safety information sheets and other means, also communicates what it believes to be appropriate warnings and cautions its employees and customers about the risks associated with excessive, prolonged inhalation of mineral dust in general and crystalline silica in particular.

     In February 1998, the Georgia Department of Natural Resources (“GDNR”) determined that both the Company and the Georgia Department of Transportation (“GDOT”) are responsible parties for investigation and remediation at the Company’s Camak Quarry in Thomson, Georgia, due to the discovery of trichloroethene (“TCE”) above its naturally occurring background concentration in a drinking water well on site. The Company provided the GDNR with information indicating that the source of the release was either from an asphalt plant and associated GDOT testing laboratory that was on the site in the early 1970’s or from a maintenance shop that was operated on the property in the 1940’s and 1950’s before the Company purchased the property. The Company entered into a Consent Order with GDNR to conduct an environmental assessment of the site and file a report of the findings. The Company and GDOT signed an agreement to share evenly the costs of the assessment work. The assessment report was completed and filed. Based upon the results of the assessment report, GDOT withdrew from the cost sharing agreement and has indicated it will not share in any future remediation costs. The Company submitted a corrective action plan to GDNR for approval on December 9, 2002. GDNR requested additional information which was duly submitted. GDNR approved the plan on June 28, 2005, and the Company completed the installation of the remediation system. The Company funded the entire cost of the corrective plan and installation of the remediation system. The groundwater monitoring and reporting, which is the last task required by the Consent Order, will occur over fifteen years. Management believes the future costs to be incurred by the Company associated with the groundwater monitoring will not have a material adverse effect on the Company’s operations or its financial condition.

     In December 1998, the GDNR determined that the Company, the GDOT, and two former asphalt plant operators are responsible parties for investigation and remediation of groundwater contamination at the Company’s Ruby Quarry in Macon, Georgia. The Company was designated by virtue of its ownership of the property. GDOT was designated because it operated a testing laboratory at the site. The two other parties were designated because both entities operated asphalt plants at the site. The groundwater contamination was discovered when the Company’s tenant vacated the premises and environmental testing was conducted. The Company and GDOT signed an agreement to share the costs of the assessment work. The report of the assessment work was filed with the GDNR. GDOT entered into a Consent Order with GDNR agreeing to conduct additional testing and any necessary remediation at the site. On May 21, 2001, GDNR issued separate Administrative Orders against the Company and other responsible parties to require all parties to participate with GDOT to undertake additional testing and any necessary remediation. The Company and GDOT submitted a corrective

13

action plan to GDNR for approval on May 20, 2002. GDNR requested additional information in connection with its consideration of the submitted plan and subsequently approved the plan on July 19, 2004. GDOT filed an amendment to the plan, which was approved on June 28, 2005. GDOT completed installation of the remediation system and has been proceeding with required groundwater monitoring and reporting activities which will occur over fifteen to twenty years. Under Georgia law, responsible parties are jointly and severally liable, and therefore, the Company is potentially liable for the full cost of funding any necessary remediation. Management believes any costs incurred by the Company associated with the future groundwater monitoring will not have a material adverse effect on the Company’s operations or its financial condition.

     In the vicinity of and beneath the Specialty Products facility in Manistee, Michigan, there is an underground plume of material originating from adjacent property which formerly was used by Packaging Corporation of America (“PCA”) as a part of its operations. The Company believes the plume consists of paper mill waste. On September 8, 1983, the PCA plume and property were listed on the National Priorities List (“NPL”) under the authority of the Comprehensive Environmental Response, Compensation and Liability Act (the “Superfund” statute). The PCA plume is subject to a Record of Decision issued by the U.S. Environmental Protection Agency (“EPA”) on May 2, 1994, pursuant to which PCA’s successor, Pactiv Corporation (“Pactiv”), is required to conduct annual monitoring. The EPA has not required remediation of the groundwater contamination. On January 10, 2002, the Michigan Department of Environmental Quality (“MDEQ”) issued Notice of Demand letters to the Company’s wholly-owned subsidiary, Martin Marietta Magnesia Specialties (“Magnesia Specialties”), PCA and Pactiv indicating that it believes that Magnesia Specialties’ chloride contamination is commingling with the PCA plume which originates upgradient from the Magnesia Specialties property. The MDEQ is concerned about possible effects of these plumes, and designated Magnesia Specialties, PCA and Pactiv as parties responsible for investigation and remediation under Michigan state law. The MDEQ held separate meetings with Magnesia Specialties, PCA, and Pactiv to discuss remediation and reimbursement for past investigation costs totaling approximately $700,000. Magnesia Specialties entered into an Administrative Order with the MDEQ to pay for a portion of MDEQ’s past investigation costs and thereby limit its liability for past costs in the amount of $20,000. Michigan law provides that responsible parties are jointly and severally liable, and, therefore, Magnesia Specialties is potentially liable for the full cost of funding future investigative activities and any necessary remediation. Michigan law also provides a procedure whereby liability may be apportioned among responsible parties if it is capable of division. The Company believes that the liability most likely will be apportioned and that any such costs attributed to Magnesia Specialties’ brine contamination will not have a material adverse effect on the Company’s operations or its financial condition, but can give no assurance that the liability will be apportioned or that the compliance costs will not have a material adverse effect on the financial condition or results of the operations of the Specialty Products business.

Employees

     As of January 31, 2008, the Company has approximately 5,255 employees, of which 3,902 are hourly employees and 1,353 are salaried employees. Included among these employees are 698 hourly employees represented by labor unions (13.3% of the Company’s employees). Of such amount, 12.5% of the Company’s Aggregates business’s hourly employees are members of a labor union, while 90% of the Specialty Products segment’s hourly employees are represented by labor unions. The Company’s principal union contracts cover employees of the Specialty Products business at the

14

Manistee, Michigan, magnesia-based chemicals plant and the Woodville, Ohio, lime plant. The Manistee collective bargaining agreement expires in August 2011. The Woodville collective bargaining agreement expires in June 2010.

ITEM 1A. RISK FACTORS AND FORWARD-LOOKING STATEMENTS

     An investment in our common stock or debt securities involves risks and uncertainties. You should consider the following factors carefully, in addition to the other information contained in this Form 10-K, before deciding to purchase or otherwise trade our securities.

     This Form 10-K and other written reports and oral statements made from time to time by the Company contain statements which, to the extent they are not recitations of historical fact, constitute forward-looking statements within the meaning of federal securities law. Investors are cautioned that all forward-looking statements involve risks and uncertainties, and are based on assumptions that the Company believes in good faith are reasonable, but which may be materially different from actual results. Investors can identify these statements by the fact that they do not relate only to historic or current facts. The words “may,” “will,” “could,” “should,” “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “intend,” “outlook,” “plan,” “project,” “scheduled,” and similar expressions in connection with future events or future operating or financial performance are intended to identify forward-looking statements. Any or all of the Company’s forward-looking statements in this Form 10-K and in other publications may turn out to be wrong.

     Statements and assumptions on future revenues, income and cash flows, performance, economic trends, the outcome of litigation, regulatory compliance, and environmental remediation cost estimates are examples of forward-looking statements. Numerous factors, including potentially the risk factors described in this section, could affect our forward-looking statements and actual performance.

     Factors that the Company currently believes could cause its actual results to differ materially from those in the forward-looking statements include, but are not limited to, those set out below. In addition to the risk factors described below, we urge you to read our Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Our aggregates business is cyclical and depends on activity within the construction industry.

     We sell most of our aggregate products to the construction industry, so our results depend on the strength of the construction industry. Since our business depends on construction spending, which can be cyclical, our profits are sensitive to national, regional, and local economic conditions. The overall economy has been hurt by mortgage security losses and the tightening credit markets. Construction spending is affected by economic conditions, changes in interest rates, demographic and population shifts, and changes in construction spending by federal, state, and local governments. If economic conditions change, a recession in the construction industry may occur and affect the demand for our aggregate products. Construction spending can also be disrupted by terrorist activity and armed conflicts.

     While our aggregate operations cover a wide geographic area, our earnings depend on the strength of the local economies in which we operate because of the high cost to transport our products relative to their price. If economic conditions and construction spending decline significantly in one or more areas, particularly in our top five revenue-generating states of North Carolina, Texas, Georgia, Iowa and South Carolina, our profitability will decrease.

16

     Within the construction industry, we sell our aggregate products for use in both commercial construction and residential construction. Commercial and residential construction levels generally move with economic cycles; when the economy is strong, construction levels rise, and when the economy is weak, construction levels fall. Commercial construction was mixed in 2007, with growth slowing during the year. In some areas we saw declining commercial construction activity, including office and retail space, as developers considered the impact of the current credit markets on construction and development plans. Businesses facing tighter credit conditions often find it difficult to obtain financing for capital investments. The residential construction market declined sharply in 2007 in connection with the housing market downtown. Further, the outlook reflects diminished demand, with recovery not expected prior to late 2009 or 2010. Approximately 12% of our aggregates shipments in 2007 were to the residential construction market.

     Our aggregate products are used in public infrastructure projects, which include the construction, maintenance, and improvement of highways, bridges, schools, prisons, and similar projects. So our business is dependent on the level of federal, state, and local spending on these projects. We cannot be assured of the existence, amount, and timing of appropriations for spending on these projects. For example, while the current federal highway law passed in 2005 provides funding of $286.4 billion for highway, transit, and highway safety programs through September 30, 2009, Congress must pass an appropriations bill each year to approve spending these funds. We cannot be assured that Congress will pass an appropriations bill each year to approve funding at the level authorized in the federal highway law. Similarly, each state funds its infrastructure spending from specially allocated amounts collected from various taxes, typically gasoline taxes and vehicle fees, along with voter-approved bond programs. Shortages in state tax revenues can reduce the amounts spent on state infrastructure projects, even below amounts awarded under legislative bills. Delays in state infrastructure spending can hurt our business. For example, we expect delays in infrastructure spending in Florida, North Carolina, South Carolina, and Texas will continue in 2008, which will limit our business growth in those states until the level and timing of spending improves.

Our aggregates business is seasonal and subject to the weather .

     Since the construction aggregates business is conducted outdoors, seasonal changes and other weather conditions affect our business. Adverse weather conditions, including hurricanes and tropical storms, cold weather, snow, and heavy or sustained rainfall, reduce construction activity and the demand for our products. Adverse weather conditions also increase our costs and reduce our production output as a result of power loss, needed plant and equipment repairs, time required to remove water from flooded operations, and similar events. Severe drought conditions can restrict available water supplies and restrict production. The construction aggregates business production and shipment levels follow activity in the construction industry, which typically occur in the spring, summer and fall. Because of the weather’s effect on the construction industry’s activity, the aggregates business production and shipment levels vary by quarter. The second and third quarters are generally the most profitable and the first quarter is generally the least profitable.

Our aggregates business depends on the availability of aggregate reserves or deposits and our ability to mine them economically.

     Our challenge is to find aggregate deposits that we can mine economically, with appropriate permits, near either growing markets or long-haul transportation corridors that economically serve

17

growing markets. As communities have grown, they have taken up attractive quarrying locations and have imposed restrictions on mining. We try to meet this challenge by identifying and permitting sites prior to economic expansion, buying more land around our existing quarries to increase our mineral reserves, developing underground mines, and developing a distribution network that transports aggregates products by various transportation methods, including rail and water, that allows us to transport our products longer distances than would normally be considered economical.

Our aggregates business is a capital-intensive business.

     The property and machinery needed to produce our products are very expensive. Therefore, we must have access to large amounts of cash to operate our businesses. We believe we have adequate cash to run our businesses. Because significant portions of our operating costs are fixed in nature, our financial results are sensitive to production volume changes.

Our businesses face many competitors.

     Our businesses have many competitors, some of whom are bigger and have more resources than we do. Some of our competitors also operate on a worldwide basis. Our results are affected by the number of competitors in a market, the production capacity that a particular market can accommodate, the pricing practices of other competitors, and the entry of new competitors in a market. We also face competition for some of our products from alternative products. For example, our magnesia specialties business may compete with other chemical products that could be used instead of our magnesia-based products.

Our future growth may depend in part on acquiring other businesses in our industry.

     We expect to continue to grow, in part, by buying other businesses. While the pace of acquisitions has slowed considerably over the last few years, we will continue to look for strategic businesses to acquire. In the past, we have made acquisitions to strengthen our existing locations, expand our operations, and enter new geographic markets. We will continue to make selective acquisitions, joint ventures, or other business arrangements we believe will help our company. However, the continued success of our acquisition program will depend on our ability to find and buy other attractive businesses at a reasonable price and our ability to integrate acquired businesses into our existing operations. We cannot assume there will continue to be attractive acquisition opportunities for sale at reasonable prices that we can successfully integrate into our operations.

     We may decide to pay all or part of the purchase price of any future acquisition with shares of our common stock. We may also use our stock to make strategic investments in other companies to complement and expand our operations. If we use our common stock in this way, the ownership interests of our shareholders will be diluted and the price of our stock could fall. We operate our businesses with the objective of maximizing the long-term shareholder return.

     We acquired 62 companies from 1995 through 2002. Some of these acquisitions were more easily integrated into our existing operations and have performed as well or better than we expected, while others have not. We have sold underperforming and other non-strategic assets, particularly lower margin businesses like our asphalt plants in Houston, Texas, and our road paving businesses in Shreveport, Louisiana, and Texarkana, Arkansas.

18

Short supplies and high costs of fuel and energy affect our businesses.

     Our businesses require a continued supply of diesel fuel, natural gas, coal, petroleum coke and other energy. The financial results of these businesses have been affected at times by the short supply or high costs of these fuels and energy. While we can contract for some fuels and sources of energy, significant increases in costs or reduced availability of these items have and may in the future reduce our financial results. For example, in 2007, increases in fuel prices lowered net earnings for the aggregates business by $0.10 per diluted share when compared with 2006 fuel prices.

Changes in legal requirements and governmental policies concerning zoning, land use, the environment, and other areas of the law, and litigation relating to these matters, affect our businesses. Our operations expose us to the risk of material environmental liabilities.

     Many federal, state, and local laws and regulations relating to zoning, land use, the environment, health, safety, and other regulatory matters govern our operations. We take great pride in our operations and try to remain in strict compliance at all times with all applicable laws and regulations. Despite our extensive compliance efforts, risk of liabilities, particularly environmental liabilities, is inherent in the operation of our businesses, as it is with our competitors. We cannot assume that these liabilities will not negatively affect us in the future.

     We are also subject to future events, including changes in existing laws or regulations or enforcement policies, or further investigation or evaluation of the potential health hazards of some of our products or business activities, which may result in additional compliance and other costs. We could be forced to invest in preventive or remedial action, like pollution control facilities, which could be substantial.

     Our operations are subject to manufacturing, operating, and handling risks associated with the products we produce and the products we use in our operations, including the related storage and transportation of raw materials, products, hazardous substances, and wastes. We are exposed to hazards including storage tank leaks, explosions, discharges or releases of hazardous substances, exposure to dust, and the operation of mobile equipment and manufacturing machinery.

     These risks can subject us to potentially significant liabilities relating to personal injury or death, or property damage, and may result in civil or criminal penalties, which could hurt our productivity or profitability. For example, from time to time we investigate and remediate environmental contamination relating to our prior or current operations, as well as operations we have acquired from others, and in some cases we have been or could be named as a defendant in litigation brought by governmental agencies or private parties.

     We are involved from time to time in litigation and claims arising from our operations. While we do not believe the outcome of pending or threatened litigation will have a material adverse effect on our operations or our financial condition, we cannot assume that an adverse outcome in a pending or future legal action would not negatively affect us.

19

Labor disputes could disrupt operations of our businesses.

     Labor unions represent 12.7% of the hourly employees of our aggregates business and 90% of the hourly employees of our specialty products business. Our collective bargaining agreements for employees of our magnesia specialties business at the Woodville, Ohio lime plant and the Manistee, Michigan magnesia chemicals plant expire in June 2010 and August 2011, respectively.

     Disputes with our trade unions, or the inability to renew our labor agreements, could lead to strikes or other actions that could disrupt our businesses, raise costs, and reduce revenues and earnings from the affected locations. We believe we have good relations with all of our employees, including our unionized employees.

Delays or interruptions in shipping products of our businesses could affect our operations.

     Transportation logistics play an important role in allowing us to supply products to our customers, whether by truck, rail, barge, or ship. Any significant delays, disruptions, or the non-availability of our transportation support system could negatively affect our operations. For example, in 2005 and partially in 2006, we experienced rail transportation shortages in Texas and parts of the southeastern region of the United States. In 2005 and 2006, following Hurricanes Katrina and Rita, we experienced significant barge transportation problems along the Mississippi River system.

     Water levels can also affect our ability to transport our products. High water levels limit the number of barges we can transport and can require that we use additional horsepower to tow barges. Low water levels can reduce the amount of material we can transport in each barge. In 2007, dry weather caused low water levels and resulted in reduced tonnage that could be shipped on a barge. Consequently, the per ton cost of transporting material was higher than normal.

     The availability of rail cars and barges can also affect our ability to transport our products. Rail cars and barges can be used to transport many different types of products. If owners sell or lease rail cars and barges for use in other industries, we may not have enough rail cars and barges to transport our products. Barges have become particularly scarce, since barges are being retired faster than new barges are being built. Shipyards that build barges are operating at capacity, so the lead time to buy or lease a new barge can extend many months. In 2005, we leased 780 additional rail cars. In 2006, we contracted to buy 50 new barges that were delivered in 2007.

     We have long-term agreements with shipping companies to provide ships to transport our aggregate products from our Bahamas and Nova Scotia operations to various coastal ports. These contracts have varying expiration dates ranging from 2008 to 2017 and generally contain renewal options. Our inability to renew these agreements or enter into new ones with other shipping companies could affect our ability to transport our products.

20

Our earnings are affected by the application of accounting standards and our critical accounting policies, which involve subjective judgments and estimates by our management. Our estimates and assumptions could be wrong.

     The accounting standards we use in preparing our financial statements are often complex and require that we make significant estimates and assumptions in interpreting and applying those standards. We make critical estimates and assumptions involving accounting matters including our stock-based compensation, our goodwill impairment testing, our expenses and cash requirements for our pension plans, our estimated income taxes, and how we account for our property, plant and equipment, and inventory. These estimates and assumptions involve matters that are inherently uncertain and require our subjective and complex judgments. If we used different estimates and assumptions or used different ways to determine these estimates, our financial results could differ.

     While we believe our estimates and assumptions are appropriate, we could be wrong. Accordingly, our financial results could be different, either higher or lower. We urge you to read about our critical accounting policies in our Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The adoption of new accounting standards may affect our financial results.

     The accounting standards we apply in preparing our financial statements are reviewed by regulatory bodies and are changed from time to time. New or revised accounting standards could change our financial results either positively or negatively. For example, beginning in 2006, we were required under new accounting standards to expense the fair value of stock options we award our management and key employees as part of their compensation. This resulted in a reduction of our earnings and made comparisons between financial periods more difficult. We urge you to read about our accounting policies and changes in our accounting policies in Note A of our 2007 financial statements.

We depend on the recruitment and retention of qualified personnel, and our failure to attract and retain such personnel could affect our business.

     Our success depends to a significant degree upon the continued services of our key personnel and executive officers. Our prospects depend upon our ability to attract and retain qualified personnel for our operations. Competition for personnel is intense, and we may not be successful in attracting or retaining qualified personnel, which could negatively affect our business.

Disruptions in the credit markets could affect our business.

     The current credit environment has negatively affected the economy, and we have considered how it might affect our business. Demand for our products, particularly in the commercial and residential construction markets, could decline if companies and consumers are unable to finance construction projects or if the economic slowdown causes delays or cancellations to capital projects. We may also have difficulty placing our commercial paper in that it may take longer than we have recently experienced and/or may cost more. We experienced such problems in August and September, 2007, but have not had placement problems since that time. We expect we will refinance our $200

21

million Notes due December 2008. However, there is no guarantee we will be able to access the capital markets at financially economical interest rates, which could negatively affect our business.

Our specialty products business depends in part on the steel industry and the supply of reasonably priced fuels.

     Our specialty products business sells some of its products to companies in the steel industry. While we have reduced this risk over the last few years, this business is still dependent, in part, on the strength of the highly-cyclical steel industry. The specialty products business also requires significant amounts of natural gas, coal, and petroleum coke, and financial results are negatively affected by high fuel prices or shortages.

Our structural composites product line has not generated any profits since its inception.

     Our structural composites product line faces many challenges before it becomes break-even or generates a profit. We cannot ensure the future profitability of this product line.

Our articles of incorporation, bylaws, and shareholder rights plan and North Carolina law may inhibit a change in control that you may favor.

     Our articles of incorporation and bylaws, shareholder rights plan, and North Carolina law contain provisions that may delay, deter or inhibit a future acquisition of us not approved by our board of directors. This could occur even if our shareholders are offered an attractive value for their shares or if many or even a majority of our shareholders believe the takeover is in their best interest. These provisions are intended to encourage any person interested in acquiring us to negotiate with and obtain the approval of our board of directors in connection with the transaction. Provisions that could delay, deter, or inhibit a future acquisition include the following:

• a classified board of directors;

• the requirement that our shareholders may only remove directors for cause;

• specified requirements for calling special meetings of shareholders; and

• the ability of our board of directors to consider the interests of various constituencies, including our employees, customers, and creditors and the local community.

In addition, we have in place a shareholder rights plan that will trigger a dilutive issuance of common stock upon substantial purchases of our common stock by a third party that are not approved by the board of directors.

     As of December 31, 2007, the Company processed or shipped aggregates from 272 quarries, underground mines, and distribution yards in 28 states and in Canada and the Bahamas, of which 98 are located on land owned by the Company free of major encumbrances, 57 are on land owned in part and leased in part, 113 are on leased land, and 4 are on facilities neither owned nor leased, where raw materials are removed under an agreement. The Company’s aggregates reserves on the average exceed 50 years of production, based on current levels of activity. However, certain locations may be subject to more limited reserves and may not be able to expand. In addition, as of December 31, 2007, the Company processed and shipped ready mixed concrete and/or asphalt products from 15 properties in 3 states, of which 11 are located on land owned by the Company free of major encumbrances and 4 are on leased land.

     The Company uses various drilling methods, depending on the type of aggregate, to estimate aggregates reserves that are economically mineable. The extent of drilling varies and depends on whether the location is a potential new site (greensite), an existing location, or a potential acquisition. More extensive drilling is performed for potential greensites and acquisitions, and in rare cases the Company may rely on existing geological data or results of prior drilling by third parties. Subsequent to drilling, selected core samples are tested for soundness, abrasion resistance, and other physical properties relevant to the aggregates industry. If the reserves meet the Company’s standards and are economically mineable, then they are either leased or purchased.

     The Company estimates proven and probable reserves based on the results of drilling. Proven reserves are reserves of deposits designated using closely spaced drill data, and based on that data the reserves are believed to be relatively homogenous. Proven reserves have a certainty of 85% to 90%. Probable reserves are reserves that are inferred utilizing fewer drill holes and/or assumptions about the economically mineable reserves based on local geology or drill results from adjacent properties. The

23

degree of certainty for probable reserves is 70% to 75%. In determining the amount of reserves, the Company’s policy is to not include calculations that exceed certain depths, so for deposits, such as granite, that typically continue to depths well below the ground, there may be additional deposits that are not included in the reserve calculations. The Company also deducts reserves not available due to property boundaries, set-backs, and plant configurations, as deemed appropriate when estimating reserves. For additional information on the Company’s assessment of reserves, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Other Financial Information — Critical Accounting Policies and Estimates- Property, Plant and Equipment” under Item 7 of this Form 10-K and the 2007 Annual Report for discussion of reserves evaluation by the Company.

     Set forth in the tables below are the Company’s estimates of reserves of recoverable aggregates of suitable quality for economic extraction, shown on a state-by-state basis, and the Company’s total annual production for the last 3 years, along with the Company’s estimate of years of production available, shown on a segment-by-segment basis. The number of producing quarries shown on the table include underground mines. The Company’s reserve estimates for the last 2 years are shown for comparison purposes on a state-by-state basis. The changes in reserve estimates at a particular state level from year to year reflect the tonnages of reserves on locations that have been opened or closed during the year, whether by acquisition, disposition, or otherwise; production and sales in the normal course of business; additional reserve estimates or refinements of the Company’s existing reserve estimates; opening of additional reserves at existing locations; the depletion of reserves at existing locations; and other factors. The Company evaluates its reserve estimates primarily on a Company-wide, or segment-by-segment basis, and does not believe comparisons of changes in reserve estimates on a state-by-state basis from year to year are particularly meaningful.

Specialty Products Business

     The Specialty Products business currently operates major manufacturing facilities in Manistee, Michigan, and Woodville, Ohio. Both of these facilities are owned.

     The Company leases a 185,000 square foot facility in Sparta, North Carolina, which serves as the assembly and manufacturing hub for the structural composites product line of Martin Marietta Composites.

Other Properties

     The Company’s principal corporate office, which it owns, is located in Raleigh, North Carolina. The Company owns and leases various administrative offices for its four reportable business segments.

     The Company’s principal properties, which are of varying ages and are of different construction types, are believed to be generally in good condition, are generally well maintained, and are generally suitable and adequate for the purposes for which they are used. During 2007, the principal properties were believed to be utilized at average productive capacities of approximately 80% and were capable of supporting a higher level of market demand.

ITEM 3. LEGAL PROCEEDINGS

     From time to time claims of various types are asserted against the Company arising out of its operations in the normal course of business, including claims relating to land use and permits, safety, health, and environmental matters (such as noise abatement, blasting, vibrations, air emissions, and water discharges). Such matters are subject to many uncertainties, and it is not possible to determine the probable outcome of, or the amount of liability, if any, from, these matters. In the opinion of management of the Company (which opinion is based in part upon consideration of the opinion of counsel), it is unlikely that the outcome of these claims will have a material adverse effect on the

26

Company’s operations or its financial condition. However, there can be no assurance that an adverse outcome in any of such litigation would not have a material adverse effect on the Company or its operating segments.

     The Company was not required to pay any penalties in 2007 for failure to disclose certain “reportable transactions” under Section 6707A of the Internal Revenue Code.

     See also “Note N: Commitments and Contingencies” of the “Notes to Financial Statements” of the 2007 Financial Statements included under Item 8 of this Form 10-K and the 2007 Annual Report and “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Environmental Regulation and Litigation” under Item 7 of this Form 10-K and the 2007 Annual Report.

ITEM 9.   CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

     None.

ITEM 9A. CONTROLS AND PROCEDURES

     As of December 31, 2007, an evaluation was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures and the Company’s internal control over financial reporting. Based on that evaluation, the Company’s management, including the CEO and CFO, concluded that the Company’s disclosure controls and procedures were effective in ensuring that all material information required to be disclosed is made known to them in a timely manner as of December 31, 2007 and further concluded that the Company’s internal control over financial reporting was effective in providing reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with generally accepted accounting principles as of December 31, 2007.

     The Company’s management, including the CEO and CFO, does not expect that the Company’s control system will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented

30

by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

     The Company’s management has issued its annual report on the Company’s internal control over financial reporting, which included management’s assessment that the Company’s internal control over financial reporting was effective at December 31, 2007. The Company’s independent registered public accounting firm has issued an attestation report that the Company’s internal control over financial reporting was effective at December 31, 2007. Management’s report on the Company’s internal controls and the attestation report of the Company’s independent registered public accounting firm are included in the 2007 Financial Statements, included under Item 8 of this Form 10-K and the 2007 Annual Report. See also “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Internal Control and Accounting and Reporting Risk” under Item 7 of this Form 10-K and the 2007 Annual Report.

     Included among the Exhibits to this Form 10-K are forms of “Certifications” of the Company’s CEO and CFO as required in accordance with Section 302 of the Sarbanes-Oxley Act of 2002 (the “Section 302 Certification”). The Section 302 Certifications refer to this evaluation of the Company’s disclosure policies and procedures and internal control over financial reporting. The information in this section should be read in conjunction with the Section 302 Certifications for a more complete understanding of the topics presented.
