PART I

ITEM 1. BUSINESS

General

     Martin Marietta Materials, Inc. (the “Company”) is the United States’ second largest producer of aggregates for the construction industry, including highways, infrastructure, commercial, and residential. The Company also manufactures and markets magnesia-based chemical products used in industrial, agricultural, and environmental applications, and dolomitic lime sold primarily to the steel industry, and is developing structural composite products for use in a wide variety of industries. In 2004, the Company’s aggregates segment accounted for 93% of the Company’s total net sales, and the Company’s specialty products segment accounted for 7% of the Company’s total net sales.

     The Company was formed in 1993 as a North Carolina corporation to succeed 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 transaction in 1996 that resulted in 100% of the Company’s Common Stock being publicly traded.

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

     Another significant acquisition in 1997 expanded the Company’s aggregates business in the middle of the country, while another significant acquisition in 1998 added the leading producer of aggregates products in Texas and provided the Company with an extensive rail network in Texas. These two transactions set the stage for numerous additional expansion acquisitions in Ohio and Indiana, the Southeast, and the Southwest, 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 also made its initial investment, as described below, in a business that would later serve as the Company’s platform for further expansion in the southwestern and western United States.

     In October 1998, the Company purchased an initial 14% interest in the business of Meridian Aggregates Company (“Meridian”). In April 2001, the Company completed the purchase of all of the remaining interests of Meridian under the purchase option terms of the original investment agreement. The purchase consideration consisted of $238 million, including the original October 1998 investment of $42 million, the retirement of debt, the forgiveness of related party obligations, and estimated amounts for certain other assumed liabilities and transaction costs, plus the assumption of normal balance sheet liabilities (the “Meridian Acquisition”). At the time of the Meridian transaction, Meridian operated 25 aggregates production facilities and seven rail-served distribution yards in 11

Table of Contents

states in the southwestern and western United States and sold aggregates to customers in 14 states, including six states in which the Company had not previously conducted any business. The Meridian Acquisition added more than 1.6 billion tons of aggregates reserves, expanded the Company’s presence in the southwest and western states, and increased its ability to use rail as a mode of transportation.

     In December 2004, the Company announced the formation of a joint venture with Hunt Midwest Enterprises, effective January 1, 2005, 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.

     In 2002, the Company completed a number of sales of nonstrategic operations in its Aggregates division, including the sale of facilities in Illinois, Iowa, Ohio, Oklahoma, Tennessee, and Virginia. In 2003, the Company continued these sales of nonstrategic operations, including the sale of facilities in Alabama, Louisiana, Missouri, Ohio, Texas, and West Virginia. In 2004 the Company divested nonstrategic aggregate facilities in Alabama, California, Tennessee, and Washington, as well as certain facilities involved with its asphalt, ready mixed concrete, and road paving operations in Louisiana, Texas, and Oklahoma. In some of these transactions, the Company concurrently entered into supply agreements to provide aggregates at market rates to certain of these businesses. The Company will continue to evaluate opportunities to divest nonstrategic assets during 2005 in an effort to redeploy capital for other opportunities.

     In May 2001, the Company, through its wholly owned subsidiary, Martin Marietta Magnesia Specialties (“Magnesia Specialties”), sold certain assets related to the refractories portion of its Magnesia Specialties business to a subsidiary of Minerals Technologies Inc. for $34 million. The Company retained certain current assets (including accounts receivable) and certain liabilities relating to the refractories business. In an accompanying manufacturing agreement, Magnesia Specialties agreed to supply the subsidiary of Minerals Technologies with certain refractories products at market rates principally from the Manistee, Michigan plant of Magnesia Specialties for a period of time following the sale. This agreement ended in 2002. The sale of Magnesia Specialties’ refractories business lessened the dependence of the Magnesia Specialties business on the steel industry. In addition, in 2003 the Magnesia Specialties business also disposed of two of its nonstrategic lines of business.

     In 2003, the Company, through its wholly owned subsidiary, Martin Marietta Composites, Inc. (“Martin Marietta Composites”), opened for business a 185,000 square foot facility in Sparta, North Carolina, which serves as the assembly and manufacturing hub for its structural composite products (“Structural Composite Products”) business.

Business Segment Information

     The Company operates in two reportable business segments: Aggregates and Specialty Products. The Specialty Products segment includes the Magnesia Specialties business and the Structural Composite Products business. Information concerning the Company’s total revenues, net sales, earnings from operations, assets employed, and certain additional information attributable to each reportable industry segment for each year in the three-year period ended December 31, 2004 is included in “Note O: Business Segments” of the “Notes to Financial Statements” on pages 32 and 33 of the Company’s 2004 Annual Report to Shareholders (the “2004 Annual Report”), which information is incorporated herein by reference.

Aggregates

     The Company’s Aggregates division processes and sells granite, limestone, sand, gravel, and other aggregates products for use in all sectors of the public infrastructure, commercial, and residential construction industries. The Aggregates division also includes the operation of its other construction materials businesses. These businesses, acquired through continued selective vertical integration by the Company, include primarily asphalt, ready mix concrete, and road paving operations.

     The Company is the United States’ second largest producer of aggregates. In 2004, the Company’s Aggregates division shipped 191.5 million tons of aggregates primarily to customers in 32 states, Canada, and the Bahamas, generating net sales and earnings from operations of $1.4 billion and $220 million, respectively.

     The Aggregates division markets its products primarily to the construction industry, with approximately 46% 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, and demographic and population shifts and to changes in the level of infrastructure spending funded by the public sector. The Company’s aggregates business covers a wide geographic area. The Company’s aggregates, asphalt products, and ready mixed concrete are sold and shipped from a network of approximately 325 quarries, distribution facilities, and plants in 28 states, Canada, and the Bahamas, although the Company’s five largest revenue-generating states (Texas, North Carolina, Georgia, Iowa, and Indiana) account for approximately 57% of total net sales by state of destination. The Company’s business is accordingly affected by the economies in these regions and has been adversely affected in part by recessions and weaknesses in these economies.

     The Company’s aggregates business is also highly seasonal, due primarily to the effect of weather conditions on construction activity within its markets. As the Company has expanded, its exposure to winter weather-related risks has increased. The Aggregates division’s operations that are concentrated in the northern region of the United States and Canada experience more severe winter weather conditions than the division’s operations in the Southeast and Southwest. 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 division’s operations 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, which have had a significant adverse impact on the financial performance of the Company. During 2004, aggregates shipments in the Company’s southeastern and Gulf Coast markets were adversely affected by four hurricanes. The Company’s Bahamas facility took two direct hits from hurricanes with limited physical damage. However, power was not restored at the facility for five weeks after the storms, resulting in no production and limited shipments during that time.

     Aggregates can be found in abundant quantities throughout the United States, and there are many producers nationwide. However, as a general rule, shipments from an individual quarry are limited because the cost of transporting processed aggregates to customers is high in relation to the value of the product itself. As a result, proximity of quarry facilities to customers is the most important factor in competition for aggregates business and helps explain the highly fragmented nature of the aggregates industry. 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 reach through increased access to rail transportation.

     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, while the balance of 7% was moved by rail. In contrast, the Company’s aggregates shipments were moved 79% by truck, 11% by rail, and 10% by water in 2004. 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. The Gulf and Atlantic coastal areas are being supplied in part from the Bahamas location, two large quarries on the Ohio River system, and a Canadian quarry on the Strait of Canso in Nova Scotia. In addition, the Company’s acquisitions have expanded its ability to ship by rail. Accordingly, in addition to increasing the Company’s geographic presence through acquisitions, the Company has also enhanced its reach through its ability to provide cost-effective coverage of coastal markets on the east and gulf coasts, as well as additional geographic areas which can be accessed economically by the Company’s expanded distribution system. In 2002, the Company completed a major project to modernize and expand the plant capacity at its Bahamas location, which provides the opportunity for the Company to capture future potential market growth and reduce costs (although there can be no assurance of such growth and cost reductions).

     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 customer typically does not pay the Company 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 Southwest and Southeast, increases 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.

Table of Contents

     During 2004, the Company experienced significant rail transportation shortages in Texas and parts of the Southeast. These shortages resulted from the downsizing in personnel and equipment made by certain railroads. Management is reviewing alternatives to address these issues. In response to these issues, rail transportation providers have focused on increasing the volume of cars related to transportation contracts and are generally enticing customers, through the freight rate structure, to accommodate unit train unloadings. Certain of the Company’s sales yards in the Southwest have the system capabilities to meet the unit train requirement.

     The waterborne distribution network 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. In 2004, the Company signed long-term agreements that provide additional dedicated shipping capacity from the Company’s Bahamas and Nova Scotia operations to its coastal ports.

     The Company’s management expects the multiple transportation modes that have been developed with various rail carriers and via deepwater ships should provide the Company with the flexibility to effectively serve customers in the Southwest and Southeast.

     The Company’s management believes the overall long-term trend for the construction aggregates industry continues to be one of consolidation, although the consolidation trend is slowing as the number of suitable acquisition targets shrinks. 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, increased market share in the Company’s core businesses, and pursuing new technological opportunities related to the Company’s existing markets.

     Prior to 1998, the Company had historically focused on the production of aggregates and had not integrated vertically in a substantial manner into other construction materials businesses. The Company became significantly more vertically integrated with a significant acquisition in 1998 and subsequent acquisitions, particularly in the Southwest, pursuant to which the Company acquired asphaltic concrete, ready mixed concrete, paving construction, trucking, and other businesses, which establish vertical integration that complement the Company’s aggregates business. These vertically integrated operations accounted for about 8% of revenues in 2004. If the Company were to continue its expansion strategy westward, where vertically integrated operations are the norm, profit margins generally would be adversely affected. Generally 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 have been acquired as supplemental operations that were part of larger acquisitions. As such they do not represent core businesses of the Company. These operations have typically resulted in losses that are insignificant to the Company as a whole. In 2004 the Company continued disposing of some of these operations. The Company continues to review carefully these operations to determine if they represent opportunities to divest nonstrategic 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 division’s 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 segment. 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 uses various drilling methods, depending on the type of aggregate, to estimate 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 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 calculation. The Company also deducts loss factors, such as property boundaries 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 — Application of Critical Accounting Policies — Property, Plant and Equipment” on pages 58-60 of the 2004 Annual Report for discussion of reserves evaluation by the Company.

     The Company generally delivers products in its Aggregates segment upon receipt of orders or requests from customers. Accordingly, there is no significant backlog information. Inventory of aggregates is generally maintained in sufficient quantities to meet rapid delivery requirements of customers.

     Less than 1% of the Aggregates division’s revenues are from foreign jurisdictions, principally Canada and the Bahamas, with revenues from customers in foreign countries totaling $15.4 million, $14.6 million, and $10.0 million, during 2004, 2003, and 2002, respectively.

Specialty Products

     The Company’s Specialty Products division consists of the Magnesia Specialties business and the Structural Composite Products business.

     Magnesia Specialties Business. The Company in 2004 also manufactured and marketed, through Magnesia Specialties, dolomitic lime and magnesia-based chemicals products for industrial, agricultural, and environmental uses. Given the high fixed costs associated with the operations of this business, excess capacity negatively affects its results of operations. A significant portion of the costs related to the production of dolomitic lime and magnesia-based products is of a fixed or semi-fixed nature. In addition, the production of dolomitic lime and certain magnesia-based products requires the use of natural gas, coal, and petroleum coke to fuel kilns. Year-over-year increases in natural gas and other fuel prices directly affect operating results.

     Magnesia Specialties’ dolomitic lime products are sold primarily to the steel industry. Accordingly, the profitability of the Magnesia Specialties business is dependent on the production of steel and the related marketplace. Magnesia Specialties’ products used in the steel industry accounted for approximately 48% of the revenues of the business in 2004, attributable primarily to the sale of dolomitic lime products. However, Magnesia Specialties’ management has shifted the strategic focus of its magnesia-based business to higher margin specialty chemicals that can be produced at volume levels that support efficient operations. Moreover, in 2004 the chemicals group portion of the Magnesia Specialties business continued to diversify in chemicals used as flame retardants, in wastewater treatment, in pulp and paper production, and in other environmental applications, and that business is not as dependent on the steel industry as is the dolomitic lime portion of the Magnesia Specialties business.

     The principal raw materials used in Magnesia Specialties’ products are dolomitic limestone and 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.

     Historically, after the brine is used in the production process, the Magnesia Specialties business must dispose of the processed brine. Typically 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 Magnesia Specialties entered into a long-term processed brine supply agreement with The Dow Chemical Company (“Dow”) pursuant to which Dow purchases processed brine from Magnesia Specialties, at market rates, for use in Dow’s production of calcium chloride products. Magnesia Specialties also entered into a venture with Dow to construct, own, and operate a processed brine supply pipeline between the Magnesia Specialties facility in Manistee, Michigan, and Dow’s facility in Ludington, Michigan. Construction of such pipeline was completed in 2003, and Dow began purchasing processed brine from Magnesia Specialties through the pipeline.

     The supply of natural and synthetic magnesia is abundant worldwide. In 2004, Magnesia Specialties purchased some of its magnesia requirements from various sources located in China. While Magnesia Specialties does not expect an interruption in the supply of magnesia from these sources, various factors associated with economic and political uncertainty in China could result in future supply interruptions. If such an interruption were to occur, Magnesia Specialties believes it could obtain alternate supplies worldwide, although there could be no assurance that Magnesia Specialties could do so at current prices. Alternatively, Magnesia Specialties believes it could adjust its mix of products and/or increase production at its Manistee, Michigan plant.

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

     Approximately 14% of the revenues of the Magnesia Specialties 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 $16.1 million, $12.5 million, and $10.3 million during 2004, 2003, and 2002, respectively. As a result of these foreign revenues, the financial results of the Magnesia Specialties business could be affected by changes in foreign currency exchange rates or weak economic conditions in the foreign markets. To mitigate the short-term effects of changes in currency exchange rates, the Magnesia Specialties business principally uses the U.S. dollar as the functional currency in foreign transactions.

     Structural Composite Products Business. The Company in 2004 also manufactured and marketed, through Martin Marietta Composites (“MMC”), structural composite products for use in a wide variety of industries. Pursuant to various agreements, MMC has rights to commercialize certain proprietary technologies related to the Company’s business. One of the agreements gives 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, such as bridge decks, marine applications, and other structures and applications. MMC continued its research and product development activities during 2004 on these structural composites technologies and initiated or continued manufacturing and marketing of selected products. Since 2002, MMC has leased a 185,000 square foot facility in Sparta, North Carolina, which serves as the assembly and manufacturing hub for the Structural Composite Products business of MMC.

     MMC is targeting several industries and the military for its fiber-reinforced polymer composite materials: infrastructure, which includes pedestrian and vehicular bridge decks; transportation, which includes specialty truck trailers and chassis, railcar components, and tractor and trailer components; and construction, which includes wall panels, temporary structures, and industrial mats. In 2004, MMC announced the installation of bridge decks in 2 states, bringing its total to 27 bridge deck installations in 13 states and 2 foreign countries utilizing these composite materials technologies. MMC continued to explore opportunities to introduce its composite bridge installations to foreign markets. MMC has rights under a licensing agreement executed in 2001 regarding the manufacturing

11


Table of Contents

and marketing of commercial specialty truck trailers in North America, utilizing fiber-reinforced composite materials. In 2002, MMC signed a licensing agreement relating to a proprietary composite sandwich technology, which MMC expects will play an important role in the product line related to flat panel applications. The first composite trailer prototype manufactured by MMC was completed in 2003 and further developed in 2004.

     MMC intends to continue to ramp up its Structural Composite Products business during 2005. Product trials and commercialization continue to be the near-term focus of MMC. However, MMC is approximately six months behind plan in commercialization of its Structural Composites Products business. Improved performance in 2005 is essential to continued investment in this business. MMC will continue to evaluate a variety of construction-related and commercial uses for composite materials, in addition to its use in bridge decks and truck trailers. While MMC expects to increase its revenues related to its Structural Composite Products business over the next five years, there can be no assurance that these technologies will become profitable.

Patents and Trademarks

     As of February 18, 2005, the Company owns, has the right to use, or has pending applications for approximately 80 patents pending or granted by the United States and various countries and approximately 62 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 either 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, 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 business, competition in the Aggregates division tends to be limited to producers in proximity to the Company’s individual 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 location and price, but quality of aggregates and level of customer service are also factors.

     The Company is the second largest producer of aggregates in the United States based on tons shipped. There are over 4,000 companies in the United States that produce aggregates. The largest five producers account for approximately 26% of the total market. The Company in its Aggregates division competes with a number of other large and small producers. The Company believes that its

12


Table of Contents

ability to transport materials by ocean vessels and river barges and its increased access to rail transportation have enhanced the Company’s ability to compete in certain extended areas. Certain of the Company’s competitors in the aggregates industry have greater financial resources than the Company.

     The Magnesia Specialties business of the Company’s Specialty Products division competes with various companies in different geographic and product areas principally on the basis of quality, price, and technical support for its products. The Magnesia Specialties business also competes for sales to customers located outside the United States, with revenues from foreign jurisdictions accounting for approximately 14% of revenues for the Magnesia Specialties business in 2004, principally in Canada, Mexico, Europe, South America, and the Pacific Rim. Certain of the Company’s competitors in the Magnesia Specialties business have greater financial resources than the Company.

     The Structural Composite Products business of the Company’s Specialty Products division is a relatively new business that competes or will compete with various companies in different geographic and product areas principally on the basis of technological advances, quality, price, and technical support. The Structural Composite Products business competes or will compete for sales to customers located outside the United States. Certain of the Company’s competitors in the Structural Composite Products business have greater financial resources than the Company.

Research and Development

     The Company conducts research and development activities principally for its Magnesia Specialties business, at its plant in Manistee, Michigan, and for its Structural Composite Products business, at its headquarters in Raleigh, North Carolina, and its plant in Sparta, North Carolina. In general, the Company’s research and development efforts in 2004 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 2004, $0.6 million in 2003, and $0.4 million in 2002 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.

     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 $5.3 million in 2004 and $5.7 million in 2003 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 less than $1 million in 2004. The Company’s capital expenditures for environmental matters were not material to its results of operations or financial condition in 2004 or 2003. Despite these 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, however, 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” on pages 31 and 32 of the 2004 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 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” on pages 21 and 22 of this Form 10-K and “Note N: Commitments and Contingencies” of the “Notes to Financial Statements” on pages 31 and 32 and “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Environmental Regulation and Litigation” on page 50 of the 2004 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 sites 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 sites are located and acquired, the Company works closely with local authorities during the zoning and permitting processes to design new quarries in such a way as to minimize disturbances. The Company frequently acquires large tracts of land so that quarry and production facilities can be situated substantial distances from surrounding property owners. Also, 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 mineral commonly called quartz. Excessive, prolonged inhalation of very small-sized particles of crystalline silica has been associated with nonmalignant lung disease. The carcinogenic potential of crystalline silica was evaluated by the International Agency for Research on Cancer and later by the U.S. National Toxicology Program. In 1987, the agency found

15


Table of Contents

limited evidence of carcinogenicity in humans but sufficient evidence of carcinogenicity in animals. The National Toxicology Program concluded in 1991 that crystalline silica is “reasonably anticipated to be a carcinogen.” In October 1996, the International Agency for Research on Cancer issued another report stating that “inhaled crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans.” The Mine Safety and Health Administration and the Occupational Safety and Health Administration both have listed the development of a crystalline silica standard as one of the regulations they expect to have under active consideration for promulgation, proposal, or review during 2004. The Occupational Safety and Health Administration has identified occupational overexposure to crystalline silica among its top five health priorities and developed a draft regulation in 2003. The Mine Safety and Health Administration (MSHA) did not issue an advance notice of proposed rulemaking for the development of a crystalline silica standard in May 2004 as had been previously announced. The issue is in the prerule status, and MSHA is preparing a detailed risk assessment and plans to complete an external peer review of a draft assessment by February 2005. The Company, through safety information sheets and other means, communicates what it believes to be appropriate warnings and cautions to employees and customers about the risks associated with excessive, prolonged inhalation of mineral dust in general and crystalline silica in particular.

     The Clean Air Act Amendments of 1990 required the EPA to develop regulations for a broad spectrum of industrial sectors that emit hazardous air pollutants, including lime manufacturing. The new standards to be established would require plants in the targeted industries to install feasible control equipment for certain hazardous air pollutants, thereby significantly reducing air emissions. The Company and other lime manufacturers through the National Lime Association, the leading industry trade association (“NLA”), worked with the EPA to define test protocols, better define the scope of the standards, determine the existence and feasibility of various technologies, and develop realistic emission limitations and continuous emissions monitoring/reporting requirements for the lime industry. The EPA received comments on its proposed technology-based standards for the industry in November 2000, and a proposed rule for the national emission standards for lime manufacturing plants was released on December 20, 2002. The proposed rules favorably addressed many of the issues raised by NLA in the negotiation process. NLA and the Company submitted comments on the proposed rules in February 2003. The EPA published the final rule in the Federal Register on January 5, 2004, and facilities must be in compliance within three years after the date of publication. The Company believes that there are several alternatives for achieving compliance with the new technology-based standard, and that any costs associated with the upgrade and/or replacement of equipment required to comply with the new regulations will not have a material adverse effect on the Company’s operations or its financial condition, but can give no assurance that the compliance costs will not have a material adverse effect on the financial condition or results of the operations of the Magnesia Specialties business.

     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

16


Table of Contents

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. The Company is waiting for GDNR to approve the plan before implementing it. The Company is funding the entire cost of future investigations and remediation which will occur over several years. Management believes any costs incurred by the Company associated with the site 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 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 is filing an amendment to the plan, and once the amendment is approved by GDNR, it is expected that GDOT will develop a schedule to implement the plan. 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. If the Company is required to fund the cost of remediation, the Company will pursue its right of contribution from the responsible parties. Management believes any costs incurred by the Company associated with the site will not have a material adverse effect on the Company’s operations or its financial condition.

     In the vicinity of and beneath the Magnesia Specialties facility in Manistee, Michigan, facility, 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. Magnesia Specialties 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 Magnesia Specialties, PCA and Pactiv indicating that it believes that Magnesia

17


Table of Contents

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 Magnesia Specialties business.

Employees

     As of February 18, 2005, the Company has approximately 5,778 employees. Approximately 4,326 are hourly employees and approximately 1,452 are salaried employees. Included among these employees are approximately 837 hourly employees represented by labor unions (approximately 14% of the Company’s employees). Approximately 18% of the Company’s Aggregates division’s hourly employees are members of a labor union, while approximately 98% of the Specialty Products division’s hourly employees are represented by labor unions. The Company’s principal union contracts cover employees of the Magnesia Specialties business at the Manistee, Michigan, magnesia-based chemicals plant and the Woodville, Ohio, lime plant. The Manistee collective bargaining agreement expires in August 2007. The Woodville collective bargaining agreement expires in June 2006.

ITEM 2. PROPERTIES

Aggregates

     As of December 31, 2004, the Company processed or shipped aggregates from 308 quarries and distribution yards in 28 states and in Canada and the Bahamas, of which 86 are located on land owned by the Company free of major encumbrances, 73 are on land owned in part and leased in part, 138 are on leased land, and 11 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, 2004, the Company processed and shipped ready mixed concrete and/or asphalt products from 17 properties in 3 states, of which 9 are located on land owned by the Company free of major encumbrances, 1 is on land owned in part and leased in part, and 7 are on leased land.

     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 region-by-region basis. 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 reserves calculations.

Specialty Products

     The Magnesia Specialties business currently operates major manufacturing facilities in Manistee, Michigan, and Woodville, Ohio, and smaller processing plants in Bridgeport, Connecticut, and Lenoir City, Tennessee. All of these facilities are owned, except Lenoir City, which is leased.

     The Structural Composite Products business leases a 185,000 square foot facility in Sparta, North Carolina, which serves as the assembly and manufacturing hub for the Structural Composite Products business 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 two 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 2004, 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, 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 Company’s operations or its financial condition. However, there can be no assurance that an adverse

21

FORWARD-LOOKING STATEMENTS — SAFE HARBOR PROVISIONS

     This Annual Report on Form 10-K and other written reports and oral statements made from time to time by the Company contain statements which constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. 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. 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 the Company’s forward-looking statements in this Annual Report on Form 10-K and in other publications may turn out to be wrong.

     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, business and economic conditions and trends in the markets the Company serves; the timing or extent of any recovery of the economy; the level and timing of federal and state transportation funding; levels of construction spending in the markets the Company serves; unfavorable weather conditions; fuel costs; transportation costs; competition from new or existing competitors; changes in environmental and other governmental regulations; ability to recognize increased sales and quantifiable savings from internal expansion projects; ability to successfully integrate acquisitions quickly and in a cost-effective manner and achieve anticipated profitability; changes in capital availability or costs; successful development and implementation of the structural composite technological process and strategic products for specific market segments; unanticipated costs or other adverse effects associated with structural composite revenue levels, product pricing, and cost associated with manufacturing ramp up; the financial strength of the structural composite customers and suppliers; business and economic conditions and trends in the trucking and composites industries in various geographic regions; possible disruption in commercial activities related to terrorist activity and armed conflict, such as reduced end-user purchases relative to expectations; the timing and occurrence of events that may be subject to circumstances beyond the Company’s control; and other risk factors listed from time to time in the Company’s filings with the SEC.

     Investors are also cautioned that it is not possible to predict or identify all such factors. Consequently, the reader should not consider any such list to be a complete statement of all potential risks or uncertainties. Other factors besides those listed may also adversely affect the Company and may be material to the Company. The forward-looking statements in this document are intended to be subject to the safe harbor protection provided by Sections 27A and 21E. These forward-looking statements are made as of the date hereof based on management’s current expectations, and the Company does not undertake an obligation to update such statements, whether as a result of new information, future events, or otherwise.

     For a discussion identifying some important factors that could cause actual results to vary materially from those anticipated in the forward-looking statements, see the Company’s Securities and Exchange Commission filings, including, but not limited to, the discussion of “Competition” on pages 12 and 13 of this Annual Report on Form 10-K, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” on pages 34-65 of the 2004 Annual Report and “Note A: Accounting Policies” and “Note N: Commitments and Contingencies” of the “Notes to Financial Statements” on pages 31 and 32, respectively, of the Audited Consolidated Financial Statements included in the 2004 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, 2004, 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, 2004 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, 2004.

     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 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.
