Martin Marietta Materials, Inc. (the Company or Martin Marietta) is a natural resource-based building materials company. The Company supplies aggregates (crushed stone, sand and gravel) through its network of approximately 350 quarries, mines and distribution yards in 28 states, Canada and The Bahamas. In 2022, aggregates product gross profit accounted for 69% of the Company’s consolidated total products and services gross profit. Martin Marietta also provides cement and downstream products, namely, ready mixed concrete, asphalt and paving services, in markets that are naturally vertically integrated and where the Company has a leading aggregates position. The Company’s heavy-side building materials are used in infrastructure, nonresidential and residential construction projects. Aggregates are also used in agricultural, utility and environmental applications and as railroad ballast. The aggregates, cement, ready mixed concrete and asphalt and paving operations are reported collectively as the “Building Materials business”. The Company also operates a Magnesia Specialties business with production facilities in Michigan and Ohio. The Magnesia Specialties business produces magnesia-based chemical products that are used in industrial, agricultural and environmental applications. It also produces dolomitic lime sold primarily to customers for steel production and soil stabilization. Magnesia Specialties’ products are shipped to customers domestically and worldwide.

On April 30, 2021, the Company acquired Tiller Corporation (Tiller), a leading aggregates and hot mix asphalt supplier in the Minneapolis/St. Paul area, a large and fast-growing midwestern metropolitan area. The Tiller acquisition complemented the Company’s existing product offerings in the surrounding areas. Additionally, Tiller sells asphalt solely as a materials provider and does not offer paving or other associated services. Tiller is reported in the Company’s East Group.

On July 30, 2021, the Company acquired assets of Southern Crushed Concrete (SCC). SCC was a leading producer of recycled concrete in the Houston area, one of the country’s largest aggregates markets. Recycled concrete is principally used as a base aggregates product in infrastructure, commercial and residential construction applications. SCC is reported in the Company’s West Group.

On October 1, 2021, the Company acquired the Lehigh Hanson West Region business (Lehigh West Region) for $2.26 billion in cash. The acquisition included a portfolio of 17 active aggregates quarries, two cement plants with related distribution terminals, and targeted downstream operations in California, Arizona, Nevada and Oregon. These operations provided a new upstream, materials-led growth platform across several of the nation’s largest megaregions in California and Arizona, solidifying the Company’s position as a leading coast-to-coast aggregates producer. The acquired cement plants, distribution terminals and California ready mixed concrete operations are classified as assets held for sale and discontinued operations as of and for the years ended December 31, 2022 and 2021. The Lehigh West Region business is reported in the Company’s West Group.

On April 1, 2022, the Company divested its Colorado and Central Texas ready mixed concrete operations to Smyrna Ready Mix Concrete LLC. This transaction optimized the Company’s aggregates-led portfolio and improved its ability to generate more attractive margins over the long term by reducing both business cyclicality and exposure to raw material cost inflation. The transaction resulted in a pretax gain of $151.9 million, inclusive of expenses incurred due to the divestiture. The divested operations and the gain on divestiture are all reported in the West Group in the Company's consolidated financial statements included in Item 8.

On June 30, 2022, the Company divested the Redding, California cement plant, related cement distribution terminals and 14 California ready mix operations for $235.0 million in cash. In addition, on July 15, 2022, the Company sold its interest in a joint venture that operates a cement distribution terminal for $15.0 million. These assets were acquired in connection with the acquisition of the Lehigh West Region business in 2021.

On August 9, 2022, the Company announced a definitive agreement to sell the Tehachapi, California cement plant and related distribution terminals for $350.0 million in cash, subject to regulatory approval and customary closing conditions. These assets were acquired in connection with the acquisition of the Lehigh West Region.

FOR FURTHER INFORMATION WITH RESPECT TO THE DEVELOPMENT OF THE COMPANY’S BUSINESS PRIOR TO 2021, SEE THE INFORMATION APPEARING UNDER THE HEADING “GENERAL” INCLUDED IN PART I, ITEM 1 OF THE COMPANY’S FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 2019, WHICH INFORMATION IS INCORPORATED BY REFERENCE.

The Company conducts its Building Materials business through two reportable segments, organized by geography: East Group and West Group. The East Group provides aggregates and asphalt products. The West Group provides aggregates, cement, downstream products and paving services. The ten largest revenue-generating states accounted for 83% of the Building Materials business' total revenues in 2022: Texas, Colorado, North Carolina, Minnesota, California, Georgia, Arizona, Iowa, Florida and Indiana. The Company’s Magnesia Specialties business is reported as a separate segment, which includes its magnesia-based chemicals and dolomitic lime businesses. For more information on the organization and geographic area of the Company’s business segments, see “Note A: Accounting Policies” and “Note P: Segments” of the “Notes to Financial Statements” of the Company’s consolidated financial statements, which appear in Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K (this Form 10-K), which information is incorporated by reference.

The profitability of the Building Materials business, which serves customers in the construction marketplace, is sensitive to national, regional and local economic conditions and construction cyclicality, which are in turn affected by fluctuations in levels of public-sector infrastructure funding; interest rates; access to capital markets; and demographic, geographic, employment and population dynamics. The heavy-side construction business is conducted outdoors, as are much of the Building Materials business’s operations. Therefore, erratic weather patterns, seasonal changes, and other weather-related conditions, including precipitation, flooding, hurricanes, snowstorms, extreme temperatures, wildfires, earthquakes and droughts, can significantly affect production schedules, shipments, costs, efficiencies and profitability. Generally, the financial results for the first and fourth quarters are subject to the impacts of winter weather, while the second and third quarters are subject to the impacts of heavy precipitation.

The Building Materials business markets its products primarily to the construction industry, with 35% of its 2022 aggregates shipments sold to contractors in connection with highway and other public infrastructure projects and the balance of its shipments sold primarily to contractors for nonresidential and residential construction projects. The Company believes the business’ mix of public sector-related shipments lessens the impacts of fluctuations in nonresidential and residential, or private-sector, construction spending.

The Building Materials business covers a wide geographic area. The five largest revenue-generating states (Texas, Colorado, North Carolina, Minnesota and California) accounted for 64% of the Building Materials business’ total revenues in 2022. The Building Materials 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 and may be affected by a decline in economic conditions, such as recession, economic downtown or inflationary conditions in the future. In 2022, aggregates shipments increased 3.3%, driven primarily by a full year of shipments in the California and Arizona operations acquired in the fourth quarter of 2021.

Aggregates, consisting of crushed stone, sand and gravel, are an engineered, granular material that is manufactured to specific sizes, grades and chemistry for use primarily in construction applications. The Company’s operations consist primarily of open pit quarries; however, the Company is the largest operator of underground aggregates mines in the United States, with 14 active underground mines located in the East Group.

Natural aggregates sources can be found in relatively homogeneous deposits in certain areas of the United States. Proximity of quarry facilities to customers’ construction sites or to long-haul transportation corridors is an important factor in competition for aggregates businesses. As a general rule, the distance truck shipments travel from an individual quarry is limited because the cost of transporting processed aggregates to customers is high in relation to the price of the product itself. The Company’s distribution system mainly uses trucks, but also has access to rail and waterborne networks where the per-mile unit costs of transporting aggregates are much lower.

The Company’s distribution network moves aggregates materials from certain domestic and offshore sources via its long-haul rail and waterborne distribution network, to markets where aggregates supply is limited. The Company’s rail network primarily serves its Texas, Florida, Colorado and Gulf Coast markets, while the Company’s locations in The Bahamas and Nova Scotia

transport materials via oceangoing ships. The Company’s strategic focus includes expanding inland and offshore capacity and acquiring distribution facilities and port locations to offload transported material. At December 31, 2022, the Company’s aggregates distribution facilities consisted of 78 terminals. The Company’s expansion of its rail-based distribution network, coupled with the extensive use of rail service, increases the Company’s dependence on and exposure to railroad performance, including track congestion, crew availability, railcar availability, locomotive availability and the ability to renegotiate favorable railroad shipping contracts. The waterborne distribution network also increases the Company’s exposure to certain risks, including, among other items, meeting minimum tonnage requirements of shipping contracts, demurrage costs, fuel costs, ship availability and weather disruptions. The Company has long-term agreements with shipping companies to provide ships to transport its aggregates to various coastal ports.

The Company generally acquires contiguous property around existing quarry locations. Such parcels can serve as buffer property or additional mineral reserves, assuming the underlying geology supports economical aggregates mining. In either instance, the acquisition of additional property around an existing quarry allows the expansion of the quarry footprint and extension of quarry life. Some locations having limited reserves may be unable to expand.

Due to the nature of the indigenous aggregates supply in the midwestern United States, a long-term capital focus for the Company is underground limestone aggregates mines. Production costs are generally higher at underground mines than surface quarries since the depth of the aggregates deposits and the access to the reserves result in higher costs related to development, explosives and depreciation costs. However, these locations often possess marketplace transportation advantages that can lead to higher average selling prices than more distant surface quarries.

The construction aggregates industry has been consolidating, and the Company has actively participated in the industry’s consolidation. The Company’s Board of Directors and management continue to review and monitor the Company’s long-term strategic plans, commonly referred to as SOAR (Strategic Operating Analysis and Review), which include assessing portfolio optimization strategies that include business combinations and arrangements with other companies engaged in similar businesses, investing in internal expansion projects in high-growth markets, divesting businesses or nonoperating assets that are not core or do not further management’s strategy and pursuing new opportunities in the Company’s existing markets or new markets. Acquisition opportunities include public companies and private sponsor-owned and family-owned businesses, as well as asset swaps and divestitures from companies executing their strategic plans, rationalizing non-core assets and repairing financially-constrained balance sheets. When acquired, new locations sometimes do not satisfy the Company’s internal safety, maintenance, pit development or other standards, and may require additional investments before benefits of the acquisitions are fully realized.

Management believes its aggregates reserves are sufficient to permit production at present operational levels for the foreseeable future. The Company does not anticipate any significant difficulty in accessing reserves used for production. The Company’s aggregates reserves average approximately 75 years, based on the 2022 annual production level. However, certain locations may be subject to more limited reserves and may not be able to expand. Moreover, environmental, zoning and land use regulations will likely make it harder for the Company to expand its existing quarries or 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.

The Company generally sells its aggregates upon receipt of customer orders or requests. The Company generally maintains inventories of aggregates products in sufficient quantities to meet the requirements of customers.

Cement is the basic agent used to bind aggregates, sand and water in the production of ready mixed concrete. Similar to aggregates, cement is used in infrastructure projects, nonresidential and residential construction, and the railroad, agricultural, utility and environmental industries. Consequently, the cement industry is cyclical and dependent on the strength of the construction sector. The Company has a strategic and leading cement position in Texas, with production facilities in Midlothian, Texas, south of Dallas/Fort Worth, and Hunter, Texas, north of San Antonio. These plants, which produce Portland and specialty cements, operated at 77% utilization in 2022. Clinker is the initial product in cement production, and the two Texas production facilities have a combined annual clinker capacity of 4.5 million tons. The Midlothian plant permit allows the Company to expand annual production by up to 0.8 million additional tons. The Company is currently undertaking a finishing capacity expansion project at the Midlothian plant, which is expected to be completed in mid-2024 and will provide 0.5 million tons of

annual incremental capacity. Further, the Company is nearing completion of converting its plants to manufacture a less carbon-intensive Portland limestone cement, known as Type 1L, which has been approved by the Texas Department of Transportation.

In 2021, as part of the Lehigh West Region acquisition, the Company acquired a cement plant in each of Redding, California and Tehachapi, California, and several cement distribution terminals. The Redding, California plant and related terminals were sold in June 2022 and the Tehachapi, California and related terminals are classified as assets held for sale as of December 31, 2022.

Calcium carbonate in the form of limestone is the principal raw material used in the production of cement. The Company owns more than 600 million tons of limestone reserves adjacent to its Texas cement production plants on Company-owned property. Management believes that its reserves of limestone are sufficient to permit production at its cement plants at the current operational levels for the foreseeable future.

Cement consumption is dependent on the time of year and prevalent weather conditions. According to the Portland Cement Association, nearly two-thirds of U.S. cement consumption occurs in the six months between May and October. Approximately 70% to 75% of all cement shipments are sent to ready-mixed concrete operators. The remainder is shipped to manufacturers of concrete-related products, contractors, materials dealers and oil well/mining/drilling companies. The Company's cement operations generally deliver their products upon receipt of customer orders or requests. Inventory for products is generally maintained in sufficient quantities to meet rapid delivery requirements of customers.

Energy accounted for approximately 28% of the cement total production cost profile in 2022. Therefore, cement profitability is affected by changes in energy prices and the available supply of these products. The Company currently has fixed-price supply contracts for portions of its natural gas, power and coal needs, but also consumes alternative fuel and petroleum coke. Further, profitability of the cement operations is also impacted by kiln maintenance, which typically requires a plant to be shut down for a period of time.

Ready mixed concrete is measured in cubic yards and specifically batched or produced for customers’ construction projects and then typically transported by mixer trucks and poured at the project site. The aggregates used for ready mixed concrete is a washed material with limited amounts of fines (such as dirt and clay). As of December 31, 2022, the Company operates 94 ready mix plants in Arizona, California and Texas. The California ready mixed concrete operations are classified as assets held for sale as of December 31, 2022 and reported as discontinued operations for the years ended December 31, 2022 and 2021. Asphalt is most commonly used in surfacing roads and parking lots and consists of liquid asphalt, or bitumen, the binding medium, and aggregates. Similar to ready mixed concrete, each asphalt batch is produced to customer specifications. As of December 31, 2022, the Company operates 38 asphalt plants in Arizona, California, Colorado and Minnesota. The Company also offers paving services in California and Colorado. Market dynamics for these downstream product lines include a highly competitive environment and lower barriers to entry compared with aggregates and cement.

The cement and downstream operations results are affected by volatile factors, including energy-related costs, operating efficiencies and weather, to a greater extent than the Company’s aggregates operations. Liquid asphalt and cement serve as key raw materials in the production of hot mix asphalt and ready mixed concrete, respectively. Therefore, fluctuations in prices for these raw materials directly affect the Company’s operating results.

The Magnesia Specialties business produces and sells dolomitic lime from its Woodville, Ohio facility and manufactures magnesia-based chemical products for industrial, agricultural and environmental applications at its Manistee, Michigan facility. These magnesia-based chemical products have varying uses, including flame retardants, wastewater treatment, pulp and paper production and other environmental applications. In 2022, 72% of Magnesia Specialties’ total revenues were attributable to chemical products, 27% to lime, and 1% to stone sold as construction materials.

Magnesia Specialties generally delivers its products upon receipt of customer orders or requests. Inventory for products is generally maintained in sufficient quantities to meet rapid delivery requirements of customers. A significant portion of the 275,000-ton dolomitic lime capacity from a lime kiln at Woodville, Ohio is committed under a long-term supply contract. In 2022, 74% of the lime shipments in the Magnesia Specialties business was sold to third-party customers, while the remaining 26% 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. In 2022, 31% of the Magnesia Specialties’ total revenues were attributable to products used in the steel industry, primarily dolomitic lime. Accordingly, a portion of the revenues and profitability of the Magnesia Specialties business is affected by production and inventory trends in the steel industry. These trends are guided by the rate of consumer consumption, the flow of offshore imports and other economic factors. The dolomitic lime business runs

most profitably at 70% or greater domestic steel capacity utilization. According to the Federal Reserve, domestic steel capacity utilization averaged 75% of capacity in 2022 versus 81% of capacity in 2021.

In the Magnesia Specialties business, a significant portion of costs is of a fixed or semi-fixed nature. The production process requires the use of natural gas, coal and petroleum coke. Therefore, fluctuations in their pricing directly affect operating results. To help mitigate this risk, the Magnesia Specialties business has fixed-price agreements for approximately 39% of its 2023 coal and natural gas needs. For 2022, the Company’s average cost per MMBtu (1,000,000 British thermal units) of natural gas increased 47% versus 2021.

Given high fixed costs, low capacity utilization can negatively affect the segment’s results from operations. Management has shifted the strategic focus of the magnesia-based business to specialty chemicals that can be produced at volume levels that support efficient operations. Accordingly, these products are not as dependent on the steel industry as the dolomitic lime product line. Management expects future organic profit growth to result from increased pricing, efficiency enhancements, rationalization of the current product portfolio and/or further cost reductions.

The principal raw materials used in the Magnesia Specialties business are dolomitic limestone and magnesium-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.

The Magnesia Specialties business is highly dependent on rail transportation, particularly for movement of dolomitic lime from Woodville to Manistee and direct customer shipments of dolomitic lime and magnesia chemicals products from both Woodville and Manistee. The segment can be affected by the specific transportation and other risks and uncertainties outlined under Item 1A, “Risk Factors,” of this Form 10-K.

As of January 31, 2023, the Company owns, has the right to use, or has pending applications for patents pending or granted by the United States and various countries and trademarks related to its 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.

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. No material part of the business as a whole, or of any segment of the Company, is dependent upon a single customer or upon a few customers. The loss of any single customer would not have a material adverse effect on any segment of the Company.

The nature of the Company’s competition varies among its products due to the widely differing amounts of capital necessary to build and maintain production facilities. Crushed stone production from quarries or mines and sand and gravel production by dredging or otherwise are moderately capital intensive. Construction of cement production facilities is highly capital intensive and requires long lead times to complete engineering design, obtain regulatory permits, acquire equipment and construct a plant. Most domestic cement producers are owned by large foreign companies operating in multiple international markets. Many of these producers maintain the capability to import cement from foreign production facilities. Ready mixed concrete production requires relatively small amounts of capital to build a concrete batching plant and acquire delivery trucks. Accordingly, economics can lead to lower barriers to entry in some concrete markets. As a result, depending on the local market, the Company may face competition from small producers as well as large, vertically-integrated companies with facilities in many markets.

The Company operates in a largely-fragmented industry, including large, public companies and a large number of small, privately-held companies. Other publicly traded companies among the ten-largest U.S. aggregates producers include the following:

Due to the localized nature of the industry resulting from the high cost of transportation relative to the price of the product, the Building Materials business primarily operates in smaller distinct areas that can vary from one another. The Company believes that its ability to transport materials by rail and waterborne vessels has enhanced its ability to compete in the building materials industry.

Capacity for cement plants is often stated in terms of clinker capacity. According to the Portland Cement Association, United States cement production is widely dispersed, with the top five companies collectively producing approximately 58% of U.S. clinker capacity. An estimated 84% of U.S. clinker capacity is owned by companies headquartered outside of the United States. The Company’s cement operations also compete with imported cement because of the higher value of the product and the existence of major ports or terminals in Texas and California.

The Company’s ready mixed concrete and asphalt and paving operations are also in markets with numerous operators, large and small.

The Magnesia Specialties business 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. While the revenues of the Magnesia Specialties business in 2022 were predominantly domestic, a portion was derived from customers located outside the United States.

The Company’s operations are subject to and affected by federal, state and local laws, rules and regulations relating to zoning, land use, mining, air emissions (including CO2 and other greenhouse gases), water use, allocation and discharges, waste management, noise and dust exposure control, reclamation and other environmental, health and safety, and 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 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 regularly monitors and reviews its operations, procedures and policies for compliance with existing laws, rules 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, including with respect to climate change. The Company has a full-time team of environmental engineers and managers that perform these responsibilities. The direct costs of ongoing environmental compliance were approximately $35.6 million in 2022 and $31.0 million in 2021 and are related to the Company’s environmental staff, ongoing monitoring costs for various matters (including those matters disclosed in this Form 10-K) and asset retirement costs. Capitalized costs related to environmental control facilities were approximately $20.0 million in 2022 and are expected to be approximately $20.0 million in 2023 and $25.0 million in 2024. The Company’s capital expenditures for environmental matters were not material to its results of operations or financial condition in 2022 and 2021. However, the Company’s expenditures for environmental matters generally have increased over time and are likely to increase in the future. Despite the Company’s compliance efforts, the risk of environmental liability is inherent in the Company’s businesses, and environmental liabilities could have a material adverse effect on the Company in the future. Complying with governmental and environmental regulations did not have and is not expected to have a material effect on the Company’s capital expenditures, earnings and competitive position, other than as discussed in this section.

Many of the applicable requirements of environmental laws are satisfied by procedures that the Company adopts as best practices in the ordinary course of its business. For example, plant equipment that is used to crush aggregates products may, in the ordinary course of operations, have an attached water spray bar that is used to clean the stone. The water spray bar also

serves as a dust control mechanism that complies with applicable environmental laws. Moreover, the Company does not separate the portion of the cost, depreciation and other financial information relating to the water spray bar that is attributable only to environmental purposes, as such an allocation would be arbitrary. 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 records costs in that category when incurred as operating expenses.

As is the case with others in the cement industry, the Company’s cement operations produce varying quantities of cement kiln dust (CKD). This production by-product consists of fine-grained, solid, highly alkaline material removed from cement kiln exhaust gas by air pollution control devices. Since much of the CKD is unreacted raw materials, it is generally permissible to recycle the CKD back into the production process, and large amounts often are treated in such manner. CKD that is not returned to the production process or sold as a product itself is disposed in landfills. CKD is currently exempted from federal hazardous waste regulations under Subtitle C of the Resource Conservation and Recovery Act.

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 their attendant regulations are complex and are subject to challenges and new interpretations by regulators and the courts. In addition, new laws are also 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 to which type of operations they will apply and the manner in which they will be implemented is more accurately defined. This process typically takes years to finalize, and the rules often change significantly from the time they 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 benefit 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 or amended from time to time and changes in facts and circumstances. The Company believes that its operations and facilities, both owned or leased, are in substantial compliance with applicable laws and regulations and any potential 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 O: Commitments and Contingencies” of the “Notes to Financial Statements” of the Company’s consolidated financial statements included under Item 8, “Financial Statements and Supplemental Data,” of this Form 10-K, and the “Environmental Regulation and Litigation" section included under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of this Form 10-K. 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, mining, production and distribution facilities for aggregates, cement, ready mixed concrete and asphalt must comply with air quality, water quality and other environmental regulations, zoning and special use permitting requirements, applicable mining regulations, and federal health and safety requirements. As the Company locates and acquires new production and distribution facilities, the Company works closely with local authorities during the zoning and permitting processes to design new quarries, mines, production and distribution facilities in such a way as to minimize disturbances. The Company frequently acquires large tracts of land so that quarry, mine, production and distribution facilities can be situated at a substantial distance from surrounding property owners. Also, in certain markets, the Company’s ability to transport material by rail and water 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 similarly situated companies, 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 (MSHA) and the Occupational Safety and Health Administration (OSHA) 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 required levels. The Company, through safety information sheets and other means, also communicates

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.

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. 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 interest rate. The future reclamation costs are not offset by potential recoveries. For additional information regarding compliance with legal requirements, see “Note O: Commitments and Contingencies” of the “Notes to Financial Statements” of the Company’s consolidated financial statements included in Item 8, “Financial Statements and Supplemental Data,” of this Form 10-K. The Company performs activities on an ongoing basis, as an integral part of the normal quarrying process, that may reduce the ultimate reclamation obligations. 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 both safety regulations required by MSHA for ongoing operations as well as final reclamation requirements. Therefore, these types of activities are included in normal operating costs and are not a part of the asset retirement obligation. Reclaimed quarry sites owned by the Company are from time to time available for sale, typically for commercial development or use as reservoirs, or have been converted for recreational use by the local community.

The Board and management have identified certain risks and opportunities below with respect to climate change, including regulatory and physical impacts, and the transition to a low-carbon economy.

Board Oversight and the Role of Management The Board of Directors has an essential role in determining the Company's strategic priorities, and climate change and other sustainability matters are an integral part of its oversight of the business. In 1994, the Company established an Ethics, Environment, Safety and Health (EESH) Committee, which currently meets at least four times annually. The EESH Committee receives reports directly from management relating to environmental, safety, ethics and other sustainability matters, including greenhouse gas (GHG) and climate change-related matters, reviews input and engagement with investors on these matters, and monitors our compliance with environmental, health and safety laws and regulations, as well as our public reporting and disclosure with respect to climate change-related risks and opportunities and other environmental issues. The EESH Committee reports to the full Board, and a number of other Board committees have overlapping responsibility for sustainability matters, including the Audit Committee and the Management Development and Compensation Committee. While the Board oversees Martin Marietta's risk management, the executive officers are responsible for the day-to-day risk management processes, and management receives at least quarterly updates from operating personnel directly responsible for compliance relating to EESH matters. Management believes this division of responsibilities is the most effective approach for addressing the risks facing the Company. The Company also has a Head of Sustainability, who reports directly to the Executive Vice President and General Counsel on climate and other sustainability matters. The Company believes the above approach has been effective in integrating sustainability as a core element of its corporate governance.

In an effort to mitigate the risks to the Company associated with climate change while ensuring and improving financial sustainability, the Company has adopted a corporate-wide management strategy that considers risks and opportunities related to climate change, which has resulted in multiple initiatives to identify and implement or evaluate GHG reduction processes and technologies that also improve operational efficiencies, including: using alternative fuels such as biodiesel; reducing overall fuel use by converting from quarry trucks to conveyor systems; right-sizing quarry trucks to match the appropriately sized truck with the size of production to reduce the number of required trips; replacing older railcars with more efficient, high-capacity models that reduce the number of required trips; adding rail capacity in lieu of truck movements; and installing state-of-the-art emissions control equipment at one of the Company’s magnesia plants and tire processing systems for fuel, as well as a larger natural gas line, at one of the Company’s cement plants. The Company’s Midlothian cement plant has been recognized by the United States Environmental Protection Agency (USEPA) as a high-performing, energy-efficient facility following investments in innovative air pollution control technologies and usage of alternative fuels.

Policy and Regulatory Matters A number of governmental bodies, including the U.S. Congress and various U.S. states, have proposed, enacted or are contemplating legislative and regulatory changes to mitigate or address the potential impacts of climate change, including provisions for GHG emissions reporting or reductions, the use of alternative fuels, carbon credits (such as a cap-and-trade system) and a carbon tax. For example, in the United States, the USEPA promulgated a rule mandating that companies considered to be large emitters of GHGs report those emissions. The manufacturing operations of the

Company’s Magnesia Specialties business release carbon dioxide, methane and nitrous oxides during the production of lime, magnesium oxide and hydroxide products. The Company’s two magnesia-based chemicals facilities, as well as its two cement plants in Texas and one recently-acquired cement plant in California, file annual reports of their GHG emissions in accordance with the USEPA reporting rule. The primary business and operations of the Company, however, including its aggregates, ready mixed concrete and asphalt and paving product lines, are not considered “major” sources of GHG emissions subject to the USEPA reporting rule. Most of the GHG emissions from aggregates plant operations are tailpipe emissions from mobile sources, such as heavy construction and earth-moving equipment.

In 2010, the USEPA also issued a GHG emissions permitting rule, referred to as the Tailoring Rule, which may require some industrial facilities to obtain permits for GHG emissions under the U.S. Clean Air Act’s Prevention of Significant Deterioration (PSD) and Title V operating permit programs. The U.S. Supreme Court ruled in June 2014 that the USEPA exceeded its statutory authority in issuing the Tailoring Rule but upheld the Best Available Control Technology (BACT) requirements for GHGs emitted by sources already subject to PSD or Title V permitting requirements for other pollutants. The Company’s cement plants, as well as its Magnesia Specialties plants, hold Title V Permits, and each (other than the Manistee, Michigan facility) is also subject to PSD requirements. It is currently unclear whether or how the USEPA may revise BACT requirements in the future. In fact, although several large-scale projects for carbon capture are in the development phase, no technologies or methods of operation for reducing or capturing GHGs have yet been proven successful in large-scale applications, other than improvements in fuel efficiency. Thus, if future modifications to the Company's facilities require PSD review for other pollutants, GHG BACT requirements could be triggered and may require significant additional costs, which the Company expects would be passed on to customers. It is not currently possible to estimate the cost of any such future requirements.

In November 2021, President Biden signed into law the Infrastructure Investment and Jobs Act (IIJ Act), which provides billions of dollars in new funding for public transit and clean energy projects intended, in part, to address climate change, including road, bridge and other major infrastructure projects. These projects, as well as new public transit and clean energy projects, require aggregates and cement for construction and may result in increased demand for our products. See Other Low-Carbon Transition Risks and Opportunities section for additional information.

Although it is too early to determine the actions the federal government will ultimately take to implement climate change-related orders, commitments and laws, or the full scope, timing or ramifications of such measures, it is clear that the current administration has already begun to make, and intends to continue to pursue, a significant and sweeping push on the climate front and, like other signatories to the Paris Agreement, intends to pursue a goal of a Net Zero GHG by 2050. It also seems probable that the USEPA and other agencies will use their rule-making authority and procurement decisions to further address climate change. Various states where the Company has operations have enacted or are considering climate change initiatives as well, and the Company may be subject to state regulations in addition to any federal laws and rules that are passed. On January 6, 2023, the USEPA proposed for public comment a reduction in the size of airborne particulate matter to fine particles that are 2.5 microns or less in diameter, or PM2.5, that will be regulated under its health-based, or primary, air regulations based on potential health impacts, including at-risk populations, with an adequate margin of safety. Under the Clean Air Act, which requires the USEPA to set two types of standards for particle pollution, consisting of primary standards to protect public health and secondary standards to protect public welfare, the USEPA is required to review the National Ambient Air Quality Standards every five years to determine whether they should be retained or revised. The particulate matter classifications were last revised in 2012. The new rules as currently proposed would revise the annual standard for particulate matter levels but retain the 24-hour standard. While the Company’s facilities will meet any adopted standard, these changes may result in significantly higher compliance costs and risks.

If and when the USEPA issues new regulations and/or Congress passes additional legislation restricting GHGs emissions, the Woodville, Ohio and Manistee, Michigan Magnesia Specialties operations, as well as the Company’s cement plants in Texas and California, which release CO2 in certain of their processes and use carbon-based fuels for power equipment, kilns and the Company’s mobile fleet, will likely be subject to these new regulations. The Company's three cement plants, like those of other cement operators, require combustion of significant amounts of fuel to generate high kiln temperatures and create carbon

dioxide as a product of the calcination process, which is an unavoidable step in making clinker. Accordingly, the Company continues to closely monitor GHG regulations and legislation and its potential impact on the Company's cement business, financial condition and product demand. The Company anticipates that any increased operating costs or taxes relating to GHG emission limitations at the Woodville or cement facilities would be passed on to customers. The magnesium oxide products produced at the Manistee operation, however, compete against other products that, due to the form and/or structure of the source material, require less energy in the calcination process, resulting in the generation of fewer GHGs per ton of production. Due to GHG emissions requirements, the Manistee facility may be required to absorb additional costs, including for taxes or capital investments, in order to maintain competitive pricing in that market. In addition, the cement produced by the Company’s cement plants, like other U.S. operators, is subject to strict limits set by the U.S. Department of Transportation (USDOT) and other agencies, including those relating to “clinker substitution”, or the replacement of ground clinker in cement with alternate materials such as pozzolan, slag and fly ash, which has implications for the Company’s fuel use and efforts to reduce GHG emissions from its cement operations. For example, various industry associations are engaged in an effort requesting the USDOT and other agencies to further revise their standards allowing for greater rates of clinker substitution, similar to the rates currently permitted for European cement producers. If higher rates of substitution and blending are, in fact, permitted in the future, the result is likely to be both reduced clinker and power consumption in cement production, which would, in turn, reduce GHGs emitted in connection with each ton of cement produced in the United States.

In light of the various regulatory uncertainties, the Company cannot presently reasonably predict the costs of any future compliance requirements. Nonetheless, the Company does not believe it will have a material adverse effect on the financial condition or results of the operations of either the Magnesia Specialties business or Building Materials business.

Physical Impacts In addition to impacts from increased regulation, climate change may result in physical impacts that could have adverse effects on the Company’s operations or financial condition. Physical impacts may include disruptions in production and/or regional supply or product distribution networks due to major storm events, shifts in regional rainfall and temperature patterns and intensities, as well as flooding from sea level changes. In addition, production and shipment levels for the Building Materials business correlate with general construction activity, which occurs outdoors and, as a result, is affected by erratic weather patterns, seasonal changes and other unusual or unexpected weather-related conditions, which can significantly affect that business. In the Company's cement and downstream operations businesses, the physical impacts of climate change may result in disruptions to its operations or its customers’ transportation activities, including impacts on production capabilities and capacities, supply chain interruptions and project delays that can impact the Company's reputation and result in additional costs to the Company. Excessive rainfall and other severe weather jeopardize production, shipments and profitability in all markets served by the Company in its Building Materials business. In addition, climate and inclement weather can reduce the useful life of an asset. In particular, the Company’s operations in the southeastern and Gulf Coast regions of the United States and The Bahamas are at risk for hurricane activity, most notably in August, September and October. The Company is also at risk for Pacific Ocean storm activity. The last few years brought an unprecedented amount of precipitation to the United States and particularly to Texas and the southeastern United States, notably the Carolinas, Florida and Georgia, where it impacted the Company’s facilities. In California and Arizona, continuing drought has led to water use restrictions in numerous water districts, and insufficient supply of water for the Company's operations in those areas could impact production. In California, recent storms and flooding have caused operational delays and challenges. While reconstruction activities may offset some or most of the financial impacts on sales and demand, any of these events could have a material adverse effect on the Company’s business and operations.

As the Company's footprint of quarries and aggregates facilities has grown nationwide, management believes it has bolstered resilience in its operations by maintaining a geographically diverse business and distribution network that is increasingly able to adjust to local disruptions and source materials from different facilities. In addition, because the Company transports aggregates products by various methods, including rail and water, it may be able to mitigate supply or transportation issues in any location caused by severe weather or disruptions in any transport modality.

Other Low-Carbon Transition Risks and Opportunities The Company’s businesses are dependent on reliable sources of energy and fuels. The Company could incur increased costs or disruptions in its operations if the price or availability of energy or fuels or other materials used in its operations is impacted by climate change regulation or severe weather. These and other climate-related risks, such as a downturn in the construction sector due to harsh weather, significant precipitation or other changes in weather, also could impact the Company’s customers, which could lead to reduced demand for the Company’s products. The Company may not be able to pass on to its customers all the costs relating to these risks.

Notwithstanding the foregoing risks and uncertainties relating to climate change, there may also be opportunities for the Company to increase its business or revenues, both in terms of the physical impacts of climate change and market opportunities associated with the transition to a low-carbon and climate-resilient economy. For example, warm and/or moderate temperatures in March and November allow the construction season to start earlier and end later, respectively, which could have meaningful positive impacts on the Company’s first- and fourth-quarter results, respectively. From a regulatory standpoint, as noted above, the recently-passed IIJ Act provides billions of dollars in new funding for roads, bridges and other major infrastructure projects which require aggregates and cement for construction. New public transit and clean energy projects that address climate change may also result in increased demand for our products. Other opportunities are likely to result from the passing of the $1.2 trillion IIJ Act, the Cornyn-Padilla Amendment that allows $104 billion of unused COVID-19 dollars to be directed to infrastructure projects, and $23 billion of voter-approved state and local transportation-related 2022 ballot initiatives, all of which will fund infrastructure growth, repair and development. In addition, the Company’s magnesium hydroxide products are used to increase fuel efficiency in various industries, including both coal- and gas-fired electricity generation, which has a direct impact on reducing energy use and GHG emissions by more GHG-intense companies. Finally, the desire for sustainable building solutions has led to greater recognition of the benefits of concrete construction in the effort to move to a circular economy through innovative products, longevity and recyclability, and increased demand for green construction projects would have a direct impact on the Company’s cement and concrete business.

The Company owns approximately 160,000 acres of land, the vast majority of which is used in connection with active facilities. The Company regularly reviews its land holdings to determine their highest and best use based on its management expertise. Land holdings that do not have economically recoverable reserves for current or future mining or are otherwise not in locations that complement the Company’s operating facilities are considered candidates for sale or development for sale.

As of January 31, 2023, the Company has approximately 9,400 employees, of which approximately 7,000 are hourly employees and approximately 2,400 are salaried employees. Approximately 1,200 hourly employees (13% of the Company’s employees) are represented by labor unions, representing 15% of the Building Materials business’ hourly employees and 100% of the Magnesia Specialties segment’s hourly employees. The Company’s principal union contracts for the Magnesia Specialties business cover employees at the Manistee, Michigan, magnesia-based chemicals plant and the Woodville, Ohio, lime plant. The Woodville and Manistee collective bargaining agreements expire in June 2026 and August 2027, respectively. The Company believes it has good relations with its employees, including its unionized workforce.

Management believes the Company’s success depends on its ability to attract, develop and retain key personnel. None of Martin Marietta’s accomplishments are possible without its employees; the people who both drive the work and are most affected by it. These individuals are the heart of Martin Marietta. The Company’s management oversees various employee initiatives to develop its employees and the Management Development and Compensation Committee regularly reviews the compensation and development programs to achieve those objectives. In 2020, the Company launched an Inclusion and Engagement Task Force, comprised of employees with diverse race, gender, background and experience, which is focused on hiring, developing and retaining diverse employees to strengthen its talent pipeline and increase employee engagement and retention.

Health and safety in the workplace is one of the Company’s core values. The Guardian Angel safety program provides that every employee has the right, and the obligation, to stop any unsafe condition and that zero safety incidents is achievable. It includes the notion that every employee acts as a wingman for other employees, to observe and act on any situation that potentially creates unsafe circumstances. The companywide safety performance achieved the sixth-consecutive year of world class or better lost-time incident rate and the second consecutive year for total injury incidence rate.

The COVID-19 pandemic underscored the importance of keeping the Company’s employees safe and healthy. In response to the pandemic, the Company took actions aligned with the Centers for Disease Control and Prevention to implement robust protocols to protect its workforce so that they can safely perform their jobs.

In 2019, the Company established a new employer brand — ONE — that reflects the thoughts, feelings and hearts of employees at every level of Martin Marietta. This included a standard approach to safety mentoring that ensures every employee has the knowledge and resources needed to complete their work safely and efficiently. The Company also established a World Class Task Force, whose mission is to improve Martin Marietta and is fostering a level of communication never before seen at the

Company. The Company has taken these steps to better allow it to grow responsibly and encourage employee engagement. In 2022, the Company began launching employee resource groups starting with a Military and Veterans Community resource group.

Our business depends on activity within the construction industry, which can be cyclical

Economic and political uncertainty can impede growth in the markets in which we operate. Demand for our products, particularly in the private nonresidential and residential construction markets, could decline if companies and consumers are unable to obtain credit for construction projects or if an economic slowdown causes delays or cancellations of capital projects. State and federal budget issues may also undermine the funding available for infrastructure spending. The lack of available credit may limit the ability of states to issue bonds to finance construction projects. As a result of these issues, several of our top revenue-generating states, from time to time, stop bidding or slow bid projects in their transportation departments.

We sell most of our aggregates (our primary business) and our cement products to the construction industry and, therefore, our results depend on that industry’s strength. Since our businesses depend on construction spending, which can be cyclical, our profits are sensitive to national, regional and local economic conditions and the intensity of the underlying spending on aggregates and cement products. Construction spending is affected by economic conditions, changes in interest rates, inflation, employment levels, demographic and population shifts, and changes in construction spending by federal, state and local governments. If economic conditions worsen, a recession in the construction industry may occur and affect the demand for our products. The recession of the late 2000s and early 2010s (the Great Recession) was an example, and our shipment volumes were significantly reduced and remain below peak shipment levels excluding the contribution of acquisitions. Construction spending can also be disrupted by terrorist activity and armed conflicts.

While our business operations cover a wide geographic area, our earnings depend on the strength of the local economies in which we operate due to the high cost to transport our products relative to their selling price. If economic conditions and construction spending decline significantly in one or more areas, particularly in our Building Materials business’ top five revenue-generating states of Texas, Colorado, North Carolina, Minnesota and California, our profitability will decrease. We experienced this situation during the Great Recession.

Demand for aggregates products, particularly in the infrastructure construction market, is affected by federal, state and local budget and deficit issues. Remote working trends or other factors that reduce miles driven can have a negative impact on various revenue streams that fund roadway projects. Further, delays or cancellations of projects in the nonresidential and residential construction markets, which combined accounted for 60% of aggregates shipments in 2022, could occur if companies and consumers are unable to obtain financing for construction projects or if consumer confidence continues to be eroded by economic uncertainty.

Our Building Materials business is seasonal and subject to the weather, which can significantly impact operations

Since the heavy-side construction business is conducted outdoors, erratic weather patterns, seasonal changes and other weather-related conditions affect our business. Adverse weather conditions, including hurricanes and tropical storms, cold weather, snow, heavy or sustained rainfall, wildfires and earthquakes, reduce construction activity, restrict the demand for our products and impede our ability to efficiently transport material. 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. Production and shipment levels of the Building Materials business’ products follow activity in the construction industry, which typically is strongest in the spring, summer and fall. Because of the weather’s effect on the construction industry’s activity, the production and shipment levels for our Building Materials business, including all of our aggregates-related downstream operations, vary by quarter. The second and third quarters are generally subject to heavy precipitation, and thus are more profitable if precipitation is lighter. The first and fourth quarters, which are subject to the impacts of winter weather, are generally the least profitable, but can be more profitable if the impact of winter weather is less. Our operations in the southeastern and Gulf Coast regions of the United States and The Bahamas are at risk for hurricane activity, most notably in August, September and October. Our California operations are at risk for Pacific Ocean storms, wildfire activity and water use restrictions in the event of severe drought conditions. In California, recent storms and flooding have caused operational delays and challenges. These weather events and conditions may be exacerbated by climate change in the near and long term.

Our Building Materials business depends on the availability of quality aggregates reserves or deposits and our ability to mine them economically

Our challenge is to find quality aggregates deposits that we can mine economically, with appropriate permits, near either growing markets or long-haul transportation corridors that economically serve applicable markets. As communities in many of our geographic markets have grown, they have settled in and around 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 methods, including rail and water. While our distribution network allows us to transport our products longer distances than would normally be considered economical, we can give no assurances that we will be successful at this strategy.

Our businesses have many competitors, some of whom are bigger and have more resources than we do. Some of our competitors 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. As other examples, our aggregates, ready mixed concrete, asphalt and paving businesses may compete with recycled asphalt and concrete products that could be used in certain applications instead of new products and our cement operations

may compete with international competitors who import products into the United States from jurisdictions with lower production and regulatory costs.

Our future growth may depend in part on acquiring other businesses in our industry, and we may acquire businesses by paying all or in part with shares of our common stock

We expect to continue to grow, in part, by acquiring other businesses. In the past, we have made acquisitions to strengthen our existing locations, expand our operations and enter new geographic markets. We will continue to pursue selective acquisitions, joint ventures or other business arrangements we believe will help our Company grow. However, the continued success of our acquisition program will depend on our ability to find and buy other attractive businesses at an appropriate 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 existing shareholders at that time will be diluted and the price of our stock could decline. We operate our businesses with the objective of maximizing long-term shareholder return.

Our integration of the acquisition or business combination with other businesses may not be as successful as projected

We have a successful history of business combinations and integration of these businesses into our heritage operations. However, in connection with the integration of any other business that we acquire, there is a risk that we will not be able to achieve such integration in a successful manner or on the time schedule we have projected or in a way that will achieve the level of synergies, cost savings or operating efficiencies we forecast from the acquisition.

Any significant business acquisition or combination we might choose to undertake may require that we devote significant management attention and resources to preparing for and then integrating our business practices and operations. Based on our history, we believe we would be successful in this integration process. Nevertheless, we may fail to realize some of the anticipated benefits of any potential acquisition or other business combination that we pursue in the future if the integration process takes longer than expected or is more costly than expected. Potential difficulties we may encounter in the integration process include the following:

In pursuing our business strategy, we conduct discussions, evaluate opportunities and enter into acquisition and divestiture agreements. Acquisitions involve significant challenges and risks, including risks that:

Divestitures also involve significant challenges and risks, including risks that:

If our cement or Magnesia Specialties businesses becomes and/or remains capacity-constrained, we may be unable to timely satisfy the demand for some of our products, and any resulting changes in customers would introduce volatility to the earnings of these segments. We can address capacity needs by enhancing our manufacturing productivity, increasing the operational availability of equipment, reducing machinery down time and extending machinery useful life. Future demand for our products may require us to expand our manufacturing capacity further, particularly through the purchase of additional manufacturing equipment. However, we may not be able to increase our capacity in time to satisfy increases in demand that may occur from time to time. Our Texas cement operations are currently capacity constrained, which may prevent us from satisfying customer orders and result in a loss of sales to competitors that are not capacity-constrained. We are permitted to expand annual production by up to 0.8 million additional tons at our Midlothian cement plant and are currently in the process of effecting an expansion to add 0.5 million tons of annual production capacity. However, we may suffer excess capacity if we increase our capacity to meet actual or anticipated demand and that demand decreases or does not materialize.

Our cement business could suffer if cement or clinker imports from other countries significantly increase or are sold in the United States in violation of U.S. fair trade laws

In the past, the cement industry has benefited from antidumping orders imposing duties on imports of cement and clinker from other countries that violated U.S. fair trade laws. Cement operators with import facilities can purchase cement from other countries, such as those in Latin America and Asia, which could compete with domestic producers. In addition, if environmental regulations increase the costs of domestic producers compared to foreign producers that are not subject to similar regulations, imported cement could achieve a significant cost advantage over domestically produced cement. An influx of cement or clinker products from countries not subject to antidumping orders, or sales of imported cement or clinker in violation of U.S. fair trade laws, could adversely affect our cement product line.

Changes in legal requirements and governmental policies concerning zoning, land use, the environment, health and safety and other areas of the law, as well as 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, air emissions (including carbon dioxide and other GHGs), water use, allocation and discharges, waste management, noise and dust control, mining, land reclamation and other environmental, health and safety matters govern our operations. Some of our operations require permits, which may impose additional operating standards and are subject to modification, renewal and revocation. Certain of our operations may from time to time involve the use of substances that are classified as toxic or hazardous within the meaning of these laws and regulations. Despite our extensive efforts to remain in strict compliance at all times with all applicable laws and regulations, the risk of liabilities, particularly environmental liabilities, is inherent in the operation of our businesses. These potential liabilities could result in material costs, including fines or personal injury or damages claims, which could have an adverse impact on our operations and profitability.

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 may result in additional or unanticipated compliance and other costs. We could be required to invest in preventive or remedial action, like pollution control facilities, which could be substantial or which could result in restrictions on our operations or delays in obtaining required permits or other approvals.

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, explosives, 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, 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 to investigate or clean-up such contamination.

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, an unexpected and material adverse outcome in a pending or future legal action could potentially have a negative effect on our Company.

Legislation or regulations to address climate change and transition to a low-carbon economy may adversely impact our business, including financial impacts

A number of governmental bodies, including the U.S. Congress and various U.S. states, have proposed, enacted or are contemplating legislative and regulatory changes to mitigate or address the potential impacts of climate change, including provisions for GHG emissions reductions or the use of alternative fuels, carbon credits (such as a cap-and-trade system) and a carbon tax. For example, in the United States, the USEPA promulgated a mandatory reporting rule covering GHG emissions from sources considered to be large emitters. The USEPA has also promulgated a GHG emissions permitting rule, referred to

as the Tailoring Rule, which may require some industrial facilities to obtain operating permits for GHG emissions under the U.S. Clean Air Act. The U.S. Supreme Court subsequently ruled in June 2014 that the USEPA exceeded its statutory authority in issuing the Tailoring Rule but upheld the BACT requirements for GHGs emitted by sources that already require Title V operating permits or are subject to PSD requirements for other pollutants. It is currently unclear whether the USEPA will proceed with revisions of the Tailoring Rule or proceed in a different direction, nor is it known how the USEPA may revise the BACT requirements. If future modifications to our Magnesia Specialties or cement facilities require PSD review for other pollutants, GHG permitting requirements may also be triggered, which could require us to incur significant additional costs. It is not possible, however, to estimate the cost of any future requirements at this time.

U.S. President Biden also has taken a number of steps to make climate change a central focus of his administration, including issuing a pair of executive orders and a presidential memorandum making climate change central to U.S. policy and setting out several administrative priorities and undertakings to reduce GHG emissions. President Biden reentered the Paris Agreement in January 2021 and later announced the United States’ reduction commitments under the Paris Agreement, including a 50% to 52% economy-wide reduction in net GHG emissions from 2005 levels by 2030. The Biden administration has also entered a pact with 103 countries and jurisdictions, known as the Global Methane Pledge, to reduce global methane emissions by 30% from 2020 levels by the end of the decade. Although it is still too early to determine the actions the federal government will ultimately take to implement these or other orders, commitments and laws, or the full scope, timing or ramifications of such measures, it is clear that the Biden administration has begun to make, and intends to continue to pursue, a significant and sweeping push on the climate front and, like other signatories to the Paris Agreement, intends to pursue a goal of a Net Zero GHG by 2050. These measures, combined with continued focus by the administration, also suggest that additional executive and/or legislative action is likely, although the timing and scope of such action is unclear. Additionally, it seems probable that the USEPA and other agencies will use their rule-making authority and procurement decisions to further address climate change. Various states where we have operations have enacted or are considering climate change initiatives as well, and we have been and may continue to be subject to state regulations in addition to any federal laws and rules that are passed. For example, California has had a cap-and-trade program for emissions rights since 2012.

In addition, although our aggregates, ready mixed concrete, asphalt and paving operations are not considered “major” sources of GHG emissions subject to the USEPA reporting rule, any additional regulatory restrictions on emissions of GHGs imposed by the USEPA would likely impact our magnesia-based chemicals operations in Woodville, Ohio, and Manistee, Michigan, as well as our two cement plants in Texas and our cement plant in California, each of which currently file annual reports of GHG emissions as required by the USEPA reporting rule. We may not be able to recover any increased operating costs, taxes or capital investments (other than with respect to any carbon reduction or capture technologies) relating to GHG emission limitations at those plants from our customers in order to remain competitive in pricing in the relevant markets. Our businesses also are dependent on reliable sources of energy and fuels. We could incur increased costs or disruptions in our operations if climate change legislation and regulation (including regulatory changes with respect to alternative fuel use) or severe weather affect the price or availability of purchased energy or fuels or other materials used in our operations.

While we do not currently believe such requirements will have a material adverse effect on the financial condition or results of the operations of either the Magnesia Specialties business or Building Materials business, in light of the various regulatory uncertainties, it is very difficult at this time to reasonably predict the costs of any future compliance requirements. We continue to monitor GHG regulations and legislation and its potential impact on our business, financial condition and product demand.

Climate change may result in physical impacts that could have adverse effects on our operations or financial condition

Given the nature of our operations, physical impacts may include disruptions in production, regional supply or product distribution networks, as well as negative impacts on the price or availability of purchased energy or fuels, due to major storm events or other severe weather, shifts in regional rainfall and temperature patterns and intensities, and flooding from sea level changes. In addition, production and shipment demand for our Building Materials business correlate with general construction activity and rely on road, rail and water transportation networks, most of which occurs outdoors and, as a result, is affected by erratic weather patterns, seasonal changes and other unusual or unexpected weather-related conditions, which can significantly affect that business. In our cement and downstream operations business, the physical impacts of climate change may result in disruptions to our operations and to our customers’ transportation activities, including impacts on production capabilities and capacities, supply chain interruptions and project delays, which can impact our reputation and result in additional costs to our Company. Excessive rainfall and other severe weather events also jeopardize production, shipments and profitability in all markets served by our Building Materials business. In particular, our operations in the southeastern and

Gulf Coast regions of the United States and The Bahamas are at risk for hurricane activity, most notably in August, September and October. In addition, our California operations are at risk for wildfires, which is exacerbated by prolonged drought, which may also result in water restrictions, while recent unprecedented storms and flooding have caused operational delays and challenges. Increased intensity and frequency of extreme weather events have been linked to climate change, and further global warming may increase the risk of adverse weather conditions. Climate and inclement weather can also reduce the useful life of an asset. These and other climate-related risks, such as a downturn in the construction sector due to harsh weather, significant precipitation or other changes in weather, could impact our customers, which could lead to reduced demand for our products. We may not be able to pass on to our customers all the costs related to mitigating these risks.

Our business is dependent on funding from a combination of federal, state and local sources

Our products are used in public infrastructure projects, which include the construction, maintenance and improvement of highways, streets, roads, bridges, schools and similar projects. Accordingly, our business is dependent on the level of federal, state and local spending on these projects. The visibility into future federal infrastructure funding was clarified and stabilized to some extent in 2015 with the passage of the Fixing America’s Surface Transportation, or FAST Act, which reauthorized federal highway and transportation funding programs. Further clarification was provided with the passage of the $1 trillion IIJ Act in November 2021, which contains a five-year surface transportation reauthorization plus $110 billion in new funding for roads, bridges and other hard infrastructure projects. At the federal level, we expect to see a meaningful impact from the IIJ Act beginning in 2023. Further, we continue to expect to see increased infrastructure spending at the state and local levels in 2023, aided by $10 billion for state departments of transportation provided by the December 2020 federal stimulus package, the Cornyn-Padilla Amendment that allows $104 billion of unused COVID-19 dollars to be directed to infrastructure projects and $23 billion of approved 2022 ballot initiatives. We cannot be assured, however, of the amount and timing of appropriations for spending on infrastructure projects.

Our operations are highly dependent upon the interest rate-sensitive construction and steelmaking industries. Therefore, our business in these industries may decline if interest rates rise and costs increase.

Notably, demand in the residential construction market in which we sell our aggregates products is affected by interest rates. The Federal Reserve aggressively raised interest rates throughout 2022 to address high inflation. The higher interest rates may affect our business in an adverse manner. The residential construction market accounted for 24% of our aggregates shipments in 2022.

Aside from these inherent risks from within our operations, our earnings are also affected by changes in short-term interest rates. However, rising interest rates are not necessarily predictive of weaker operating results.

Rising interest rates could also result in disruptions in the credit markets, which could affect our business, as described in greater detail under Disruptions in the credit markets could affect our business risk factor.

A number of factors may increase our future effective income tax rate, including:

The IIJ Act imposes a minimum corporate income tax rate of 15% on companies with at least $1 billion of pretax earnings. Any significant increase in our future effective income tax rate could reduce our net earnings and free cash flow for future periods.

Environmental, social and governance matters and any related reporting obligations may impact our businesses

Investors, other stakeholders, and U.S. and international regulators are increasingly focused on environmental, social and governance (ESG) matters. For example, new proposed U.S. laws and regulations relating to and requiring disclosure of ESG matters, including those relating to sustainability, climate change, supply chain, human capital, diversity and cybersecurity, are under consideration or being adopted, or may be proposed in the future. These requirements have resulted in and may continue to result in our need to make additional investments and implement new practices and reporting processes, all entailing management attention and additional compliance risk. Any failure or perceived failure to achieve or accurately report on our current or future ESG-related commitments, including our GHG reduction and net zero targets, and any differences between our commitments and those of any companies to which we are compared, could harm our reputation, adversely affect our ability to effectively compete (including as a result of disclosure of proprietary information regarding our plants or changes in our ability to raise capital), adversely affect our recruitment and retention efforts or expose us to potential legal liability. In addition, while we are committed to pursuing our sustainability objectives, there is no assurance that we will achieve any of our ESG goals or commitments, that low- or non-carbon-based energy sources and technologies required to meet long-term emissions reductions in some of the sectors in which we operate will be available at scale in the U.S. on an economically feasible basis or that our suppliers can meet sustainability, diversity and other standards that are required by current or future laws or established by our investors and other stakeholders. Failure to meet these commitments could result in reputational harm to our Company and changes regarding climate risk management and practices may result in higher regulatory and compliance risks and costs.

Our businesses could be adversely affected by new waves of COVID-19 or its variants, or any other outbreak of disease, epidemic or pandemic, or similar public health threat, or fear of such an event and its related economic and societal response

Our businesses could be negatively impacted by the widespread outbreak of an illness or other communicable disease, or any other public health crisis that results in economic and trade disruptions. Public health threats like COVID-19 or its variants can negatively impact economic activity, consumer confidence and discretionary spending, and overall market conditions and these conditions could have an impact on our Company to the extent that they occur in regions where our Building Materials business principally operates. Further, COVID-19 or other outbreaks of illnesses could negatively affect the health of our employees, employee productivity, customer purchasing patterns and fulfillment of purchase orders, availability of supplies, pricing for raw materials and the ability to transport materials via the Company’s distribution network. We actively monitor public health situations as part of our health and safety measures and acted during the pandemic to comply with federal, state and local mandates and to protect the health and safety of our employees. We may take further actions that alter our business operations, including any that may be required by federal, state or local authorities or that we determine are in the best

interests of our employees, customers, suppliers, vendors, communities and other stakeholders as we adapt to public health events from time to time.

Labor unions represent approximately 15% of the hourly employees of our Building Materials business and all of the hourly employees of our Magnesia Specialties 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 2026 and August 2027, 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 depend on the recruitment and retention of qualified personnel, and our failure to attract and retain such personnel could adversely affect our business

Our success depends to a significant degree upon the continued services of, and on our ability to attract and retain, our key personnel and executive officers, including qualified management, technical, marketing and sales, and support personnel. Competition for such personnel is intense, and we may not be successful in attracting or retaining such qualified personnel, which could negatively affect our business. In addition, because of our reliance on our senior management team, the unanticipated departure of any key member could have an adverse effect on our business. Our future success depends, in part, on our ability to identify and develop or recruit talent to succeed our senior management and other key positions throughout the organization. If we fail to identify and develop or recruit successors, we are at risk of being harmed by the departures of these key employees. Effective succession planning is also important to our long-term success. Failure to ensure effective transfer of knowledge and smooth transitions involving key employees could hinder our strategic planning and execution.

Investment returns on our pension assets may be lower than expected, or interest rates may decline, requiring us to make significant additional cash contributions to our benefit plans

A portion of our current and former employees has accrued benefits under our defined benefit pension plans. Requirements for funding our pension plan liabilities are based on a number of actuarial assumptions, including the expected rate of return on our plan assets and the discount rate applied to our pension plan obligations. Fluctuations in equity market returns and changes in long-term interest rates could increase our costs under our defined benefit pension plans and may significantly affect future contribution requirements. It is unknown what the actual investment return on our pension assets will be in future years and what interest rates may be at any given point in time. We cannot therefore provide any assurance of what our actual pension plan costs will be in the future, or whether we will be required under applicable law to make future material plan contributions.

Our reputation, ability to do business and results of operations could be impaired by improper conduct by any of our employees, agents or business partners

We are subject to regulation under a wide variety of U.S. federal and state and some non-U.S. laws, regulations and policies, including laws related to anticorruption, antibribery, export and import compliance, antitrust and money laundering, due to our operations. We cannot provide assurance our compliance policies and internal controls will always protect us from the improper conduct of our employees, agents and business partners. Any violations of law or improper conduct could damage our reputation and, depending on the circumstances, subject us to, among other things, civil and criminal penalties, material fines, equitable remedies (including profit disgorgement and injunctions on future conduct), securities litigation and a general loss of investor confidence, any one of which could have a material adverse impact on our business prospects, financial condition, results of operations, cash flows and the market value of our stock.

The property and machinery needed to produce our products are very expensive. Therefore, we require large amounts of cash to operate our businesses. We believe that our cash on hand, along with our projected operating cash flows and our available

financing resources, is adequate to support our anticipated operating and capital needs. Our ability to generate sufficient cash flow depends on future performance, which will be subject to general economic conditions, industry cycles and financial, business and other factors affecting our operations, many of which are beyond our control. If we are unable to generate sufficient cash to operate our business, we may be required, among other things, to reduce or delay planned capital or operating expenditures.

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. 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.

The accounting standards we apply in preparing our financial statements are reviewed by regulatory bodies and are periodically changed. New or revised accounting standards could, either positively or negatively, affect results reported for periods after adoption of the standards as compared with the prior periods, or require retrospective application changing results reported for prior periods. We urge you to read about our accounting policies in Note A: Accounting Policies of our consolidated financial statements included under Item 8, “Financial Statements and Supplementary Data,” of this Form 10-K.

Reports from the Public Company Accounting Oversight Board’s (PCAOB) inspections of public accounting firms continue to outline findings and recommendations that could require these firms to perform additional work as part of their financial statement audits. Our costs to respond to these additional requirements may increase.

Impairment charges could have a material adverse effect on our financial results

Goodwill and other acquired intangible assets expected to contribute indefinitely to our cash flows are not amortized, but must be evaluated for impairment by management at least annually. If the carrying value of a reporting unit exceeds its fair value, the reporting unit's goodwill is considered impaired and a non-cash charge to earnings is recorded for the difference. If the carrying value of an indefinite-lived intangible asset is greater than its fair value, the intangible asset is considered impaired and is reduced to fair value via a non-cash charge to earnings. Future events may occur that would adversely affect the fair value of our goodwill or other acquired intangible assets and require impairment charges. Such events may include, but are not limited to, lower-than-forecasted revenues, construction growth rates that fall below our assumptions, actions of key customers, increases in discount rates, continued economic uncertainty, higher levels of unemployment, weak consumer confidence, lower levels of discretionary consumer spending and a decline in the trading price of our common stock. We continue to evaluate the impact of economic and other developments to assess whether impairment indicators are present. Accordingly, we may be required to perform impairment tests based on changes in the economic environment and other factors, and these tests could result in impairment charges in the future.

We have considered the current economic environment and its potential impact to our business. Demand for aggregates products, particularly in the infrastructure construction market, has historically been negatively affected by federal and state budget challenges and the uncertainty over future highway funding levels. Further, delays or cancellations to capital projects in the nonresidential and residential construction markets could occur if companies and consumers are unable to obtain financing for construction projects or if consumer confidence is eroded by economic uncertainty.

A recessionary construction economy can also increase the likelihood we will not be able to collect all of our accounts receivable from our customers. We are protected in part, however, by payment bonds posted by many of our customers or end-users, as well as statutory lien rights. Nevertheless, we may experience a delay in payment from some of our customers during a

construction downturn, which would negatively affect operating cash flows. Historically, our bad debt write-offs have not been significant to our operating results, and we believe our allowance for credit losses is adequate.

The credit environment could impact our ability to borrow money in the future. Additional financing or refinancing might not be available and, if available, may not be at economically favorable terms. Further, an increase in leverage could lead to deterioration in our credit ratings. A reduction in our credit ratings, regardless of the cause, could also limit our ability to obtain additional financing and/or increase our cost of obtaining financing. There is no guarantee we will be able to access the capital markets at financially economical interest rates, which could negatively affect our business.

We may be required to obtain financing in order to fund certain strategic acquisitions, if they arise, or to refinance our outstanding debt. It is possible a large strategic acquisition would require that we issue new equity and debt securities in order to maintain our investment-grade credit rating and could result in a ratings downgrade notwithstanding our issuance of equity securities to fund the transaction. We are also exposed to risks from tightening credit markets, through the interest payable on any variable-rate debt, including the interest cost on future borrowings under our credit facilities. While we believe our credit ratings will remain at a composite investment-grade level, we cannot be assured these ratings will remain at those levels. Also, while we believe our Company will continue to have adequate credit available to meet its needs, there can be no assurance of that.

Our Magnesia Specialties business faces currency risks from its overseas activities

Our Magnesia Specialties business sells some of its products outside the United States. Therefore, the operations of the Magnesia Specialties business are affected from time to time by the fluctuating values of the currency exchange rates of the countries in which it does business in relation to the value of the U.S. Dollar. The business tries to mitigate the short-term effects of currency exchange rates by primarily denominating sales in the U.S. Dollar. This still leaves the business subject to certain risks, depending on the strength of the U.S. Dollar.

Unexpected equipment failures, catastrophic events and scheduled maintenance may lead to production curtailments or shutdowns

Our manufacturing processes are dependent upon critical pieces of equipment, such as our kilns and finishing mills. This equipment, on occasion, may be out of service as a result of planned or unplanned maintenance, failures or damage during accidents. In addition to equipment failures, our facilities are also subject to the risk of catastrophic loss due to unanticipated events such as fires, explosions or violent weather conditions. We have scheduled outages that can range from one to several weeks at least once a year to refurbish our cement and dolomitic lime production facilities. In 2022, our cement and Magnesia Specialties operations incurred shutdown costs of $33.3 million and $6.0 million, respectively. Any significant interruption in production capability may require us to make significant capital expenditures to remedy problems or damage as well as cause us to lose revenue due to lost production time.

Our paving operations face challenges when our contracts have penalties for late completion. In some instances, including many of our fixed-price contracts, we guarantee project completion by a certain date. If we subsequently fail to complete the project as scheduled, we may be held responsible for costs resulting from the delay, generally in the form of contractually agreed-upon liquidated damages. Under these circumstances, the total project cost could exceed our original estimate, and we could experience a loss of profit or a loss on the project. In our paving operations, we also have fixed-price and fixed-unit-price contracts where our profits can be adversely affected by a number of factors beyond our control, which can cause our actual costs to materially exceed the costs estimated at the time of our original bid. These same issues and risks can also impact some of our contracts in our asphalt and ready mixed concrete operations. These risks are somewhat mitigated by the fact that a majority of our road paving contracts are for short-term projects.

Our ready mixed concrete and asphalt and paving product lines have lower profit margins and operating results can be more volatile

Our ready mixed concrete and asphalt and paving operations typically generate lower profit margins than our aggregates and cement operations due to potentially volatile input costs, highly competitive market dynamics and lower barriers to entry. To reduce our exposure to fluctuations in raw materials costs, we divested our ready mixed concrete operations in Colorado and Central Texas in 2022.

Short supplies and high costs of fuel, energy and raw materials affect our businesses

Our businesses require a continued supply of diesel fuel, natural gas, coal, petroleum coke and other energy. Our financial results have historically been affected by the short supply or high costs of these fuels and energy. Changes in energy costs also affect the prices that we pay for related supplies, including explosives, conveyor belting and tires. While we can contract for some fuels and sources of energy, such as fixed-price supply contracts for natural gas, coal and petroleum coke, significant increases in costs or reduced availability of these items have and may in the future reduce our financial results. Moreover, fluctuations in the supply and costs of these fuels and energy can make planning for our businesses more difficult. Because of the fluctuating trends in diesel fuel prices, we may enter into fixed-price fuel agreements from time to time for a portion of our diesel fuel to reduce our diesel fuel price risk.

Cement production requires large amounts of energy, including electricity and fossil fuels. Energy costs represented approximately 28% of the 2022 production costs of our cement operations. Therefore, the cost of energy is one of our largest expenses. Prices for energy are subject to market forces largely beyond our control and can be volatile. Cost increases that we are unable to pass through in the form of price increases for our products or disruption of the uninterrupted supply of fuel and electricity could adversely affect us. Accordingly, energy cost volatility can adversely affect the financial results of our cement operations. The cement operations have fixed-price agreements for a portion of their 2023 coal, power and natural gas needs.

Similarly, our downstream operations also require a continued supply of liquid asphalt and cement, which serve as key raw materials in the production of hot mix asphalt and ready mixed concrete, respectively. Some of these raw materials we produce internally, but most are purchased from third parties. These purchased raw materials are subject to potential supply constraints and significant price fluctuations, which are beyond our control. The financial results of our ready mixed concrete and asphalt and paving operations have been affected by the short supply or high costs of these raw materials. We generally see frequent volatility in the costs for these raw materials.

Our Magnesia Specialties business has fixed-price agreements for approximately 39% of its 2023 coal and natural gas needs.

Cement competition is often based primarily on price, which is highly sensitive to changes in supply and demand. Prices may fluctuate significantly in response to relatively minor changes in supply and demand, general economic conditions and other market conditions, which we cannot control. When cement producers increase production capacity or more cement is imported into the market, an oversupply of cement in the market may occur if supply exceeds demand. In that case, cement prices generally decline. We cannot be assured that prices for our cement products sold will not decline in the future or that such decline will not have a material adverse effect on our cement product line.

Our Magnesia Specialties business depends in part on the steel industry and the supply of reasonably priced fuels

Our Magnesia Specialties 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 cyclical steel industry. Our Magnesia Specialties business also requires significant amounts of natural gas, coal and petroleum coke, and financial results are negatively affected by increases in fuel prices or shortages.

We are dependent on information technology and our systems and infrastructure face certain risks, including cybersecurity risks and data leakage risks

Our operations rely on the secure processing, storage and transmission of confidential, sensitive, proprietary and other types of information relating to our business operations, as well as confidential and sensitive information about our customers and employees maintained in our computer systems and networks, certain products and services and in the computer systems and networks of our third-party vendors, including cloud-based systems and managed service providers. Cyber threats are rapidly evolving as data thieves and hackers have become increasingly sophisticated and carry out direct large-scale, complex automated attacks against a company or through vendor software supply chain compromises. In addition, we have relied on our information technology infrastructure to support remote work from time to time and may need to do so in the future,

which can increase cyber risks. We are not able to anticipate or prevent all such attacks and could be held liable for any resulting material security breach or data loss. In addition, it is not always possible to deter misconduct by employees or third-party vendors.

We have experienced attacks to breach the security of our information technology systems, although all such breaches have been detected early and before any sensitive data or access was impacted or taken. Breaches of our technology systems, or those of our vendors and customers, whether from circumvention of security systems, denial-of-service attacks or other cyber-attacks, hacking, “phishing” attacks, computer viruses, ransomware or malware, employee or insider error, malfeasance, social engineering, vendor software supply chain compromises, physical breaches or other actions, may result in manipulation or corruption of sensitive data, material interruptions or malfunctions in our Company’s or such vendors’ and customers’ websites, applications, data processing and certain products and services, or disruption of other business operations. Furthermore, any such breaches could compromise the confidentiality and integrity of material information held by our Company (including information about our business, employees or customers), as well as sensitive personally identifiable information, the disclosure of which could lead to identity theft. Breaches of our products that rely on technology and internet connectivity can expose our Company to product and other liability risk and reputational harm. Measures that we take to avoid, detect, mitigate or recover from material incidents, may be insufficient, circumvented, or may become ineffective.

We have invested and continue to invest in risk management and information security and data privacy measures in order to protect our systems and data, including employee training, organizational investments, incident response plans, table top exercises and technical defenses. The cost and operational consequences of implementing, maintaining and enhancing further data or system protection measures could increase significantly to overcome increasingly intense, complex and sophisticated global cyber threats. Despite our best efforts, we are not fully insulated from data breaches and system disruptions. Recent well-publicized security breaches at other companies have led to enhanced government and regulatory scrutiny of the measures taken by companies to protect against cyber attacks, and may in the future result in heightened cybersecurity requirements, including additional regulatory expectations for oversight of vendors and service providers. Any material breaches of cybersecurity, including the accidental loss, inadvertent disclosure or unapproved dissemination of proprietary information or sensitive or confidential data, or media reports of perceived security vulnerabilities to our systems, products and services or those of third parties relied upon by our Company could cause us to experience reputational harm, loss of customers and revenue, fines, regulatory actions and scrutiny, sanctions or other statutory penalties, litigation, liability for failure to safeguard our customers’ information or financial losses that are either not insured against or not fully covered through any insurance maintained by our Company. The report, rumor or assumption regarding a potential breach may have similar results, even if no breach has been attempted or occurred. Any of the foregoing may have a material adverse effect on our business, operating results and financial condition.

The California Consumer Privacy Act of 2018 (CCPA), which went into effect in January 2020, provides, among other things, a new private right of action for data breaches, requires companies that process information on California residents to make new disclosures to consumers about their data collection, use and sharing practices, and provides consumers with additional rights. The California Privacy Rights and Enforcement Act, which became effective on January 1, 2023, amends and expands the CCPA, creating new industry requirements, consumer privacy rights and enforcement mechanisms. Similarly, to conduct certain of our operations, we move data across national borders, and consequently are subject to a variety of continuously evolving and developing laws and regulations in the United States and abroad regarding privacy, data protection and data security. The scope of the laws that may be applicable to our business is often uncertain and may be conflicting, particularly with respect to foreign laws. For example, the European Union’s General Data Protection Regulation (GDPR), which became effective in May 2018, greatly increased the jurisdictional reach of European Union law and added a broad array of requirements for handling personal data, including the public disclosure of significant data breaches. Our reputation and brand and our ability to attract new customers could also be adversely impacted if we fail, or are perceived to have failed, to properly respond to security breaches of ours or third party’s information technology systems. Such failure to properly respond could also result in similar exposure to liability.

All of these evolving compliance and operational requirements impose significant costs that are likely to increase over time. Privacy laws that may be implemented in the future will continue to require changes to certain business practices, thereby increasing costs, or may result in negative publicity, require significant management time and attention, and may subject our Company to remedies that may harm our business, including fines or demands or orders that we modify or cease existing business practices.

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 or water. We also rely heavily on third-party truck and rail transportation to ship coal, natural gas and other fuels to our plants. Any significant delays, disruptions or the non-availability of our transportation support system could negatively affect our operations. Transportation operations are subject to capacity constraints, high fuel costs and various hazards, including extreme weather conditions and slowdowns due to labor strikes and other work stoppages. In Texas, we compete for third-party trucking services with operations in the oil and gas fields, which can significantly constrain the availability of those services to us. If there are material changes in the availability or cost of transportation services, we may not be able to arrange alternative and timely means to transport our products or fuels at a reasonable cost, which could lead to interruptions or slowdowns in our businesses or increases in our costs.

The availability of railcars can also affect our ability to transport our products. Railcars can be used to transport many different types of products across all of our segments. If owners sell or lease railcars for use in other industries, we may not have enough railcars to transport our products.

We have long-term agreements with shipping companies to provide ships to transport our aggregates products from our Bahamas and Nova Scotia operations to various coastal ports. These contracts have varying expiration dates ranging from 2023 to 2027 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.

Some of our products are distributed by barges along rivers in Ohio and West Virginia. We may experience, to a lesser degree, risks associated with distributing our products by barges, including significant delays, disruptions or the non-availability of our barge transportation system that could negatively affect our operations, water levels that could affect our ability to transport our products by barge, and barges that may not be available in quantities that we might need from time to time to support our operations.

Our articles of incorporation and bylaws and North Carolina law may inhibit a change in control that you may favor

Our restated articles of incorporation and restated bylaws 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:

Additionally, the occurrence of certain change-of-control events could result in an event of default under certain of our existing or future debt instruments.

There are no unresolved written comments that were received from the staff of the SEC one hundred and eighty (180) days or more before the end of the Company's fiscal year relating to its periodic or current reports under the Exchange Act.

As of December 31, 2022, the Company processed or shipped aggregates from 344 quarries, mines and distribution terminals in 28 states, Canada and The Bahamas. No individual quarry or mine is material to the Company’s business or financial condition. The Company’s aggregates reserves, on average, represent approximately 75 years at the 2022 annual production level. However, certain locations may be subject to more limited reserves and may not be able to expand. As of December 31, 2022, the Company operated 78 aggregates distribution terminals. In total, aggregates locations (quarries, mines and distribution terminals) include 154 located on land owned by the Company free of major encumbrances, 63 on land owned in part and leased in part, 114 on leased land, and 13 on facilities neither owned nor leased where raw materials are removed under an agreement. In addition, as of December 31, 2022, the Company processed and shipped ready mixed concrete and asphalt products from 132 properties in five states, of which 98 are located on land owned by the Company free of major encumbrances, 3 are on land owned in part and leased in part, 28 are on leased land and 3 are at facilities neither owned nor leased.

An overview of the Company’s quarrying and mining operations is included in “Business—Building Materials Business” and “Business—Environmental and Governmental Regulations,” included in Item 1, “Business” of this Form 10-K, which is incorporated herein by reference. The following map presents the locations of these quarries and underground mines, including the limestone reserves adjacent to the California cement plant that is classified as held for sale:

Mineral reserves and mineral resources for the Company’s aggregates and cement businesses have been prepared in accordance with the disclosure requirements of subpart 1300 of U.S. Securities and Exchange Commission Regulation S-K. Mineral resources represent concentrations or occurrences of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. A measured mineral resource is that part of the mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling in sufficient detail to support detailed extraction planning and final evaluation of the economic viability of the deposit to be quarried or mined. An indicated mineral resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of

adequate geological evidence and sampling in sufficient detail to support mine planning and evaluation of the economic viability of the deposit of the material to be quarried or mined. Inferred mineral resources are that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The Company has no inferred resources as of December 31, 2022.

A mineral reserve is an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. A probable mineral reserve is the economically mineable part of an indicated and, in some cases, a measured mineral resource. A proven mineral reserve is the economically mineable part of a measured mineral resource and can only result from the conversion of a measured mineral resource. The Company estimates proven and probable mineral reserves based on the results of drilling and testing completed by or under the supervision of qualified persons.

The Company uses various exploratory drilling methods, depending on the type of deposit, to estimate mineral reserves that are economically mineable. The extent of drilling varies depending on the complexity of the mineral deposit and 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 reputable third parties. Subsequent to drilling, selected drill samples are tested by an accredited laboratory for soundness, abrasion resistance and other physical properties relevant to the aggregates industry. If the mineral reserves meet the Company’s standards and are economically mineable, they are either leased or purchased. Once in operation, routine quality control testing is performed to ensure the quality grade of aggregates continues to meet specifications.

In determining the amount of reserves, evaluations are completed by or under the supervision of qualified Company personnel using industry best practices and internal controls defined by the Company. Reserve estimates represent net tons after consideration of applicable losses incurred during mining and plant processing. The Company’s policy is to exclude from reserve estimates the portions of a mineral deposit that are not available due to property boundaries, set-backs and plant configurations, as deemed appropriate when estimating reserves. The Company uses the same methods of analysis to evaluate and estimate the amount of its mineral reserves used in the cement manufacturing process for its cement operations as it does for its aggregates operations. 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” included under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of this Form 10-K. While the mineral reserve and resource classification categories (proven and probable) identify relative confidence of reserve estimates, there is inherent risk associated with such estimates. The Company bases estimates on the information known at the time of determination and regularly reevaluates reserves whenever new information indicates a material change in reserves at one of the Company’s sites.

In general, quarry and mining facilities must comply with air quality, water quality, 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.

Set forth in the tables below are the Company’s estimates as of December 31, 2022 of proven and probable mineral reserves of aggregates (crushed stone and sand and gravel) and measured, indicated and inferred mineral resources of aggregates (exclusive of proven and probable reserves), shown on a geographic division basis. The East Division includes Alabama, Florida, Georgia, Maryland, North Carolina, Pennsylvania, South Carolina, Tennessee, Virginia, Canada and The Bahamas. The Central Division includes Indiana, Iowa, Kansas, Kentucky, Minnesota, Missouri, Nebraska, Ohio and West Virginia. The Southwest Division includes Arkansas, Louisiana, Oklahoma and Texas. The West Division includes Arizona, California, Colorado, Utah, Washington and Wyoming. The reserve estimates shown were determined to be economically mineable using a reasonable and justifiable price for salable product as of December 31, 2021 with respect to each division for each product category of aggregates resources. The Company’s estimate of resources and reserves of aggregates shown in the tables below includes resources and reserves that would be devoted for use in the Company’s cement product line and Magnesia Specialties business.

The following presents the Company’s total annual production for the last three years, shown on a product line-by-product line basis.

As of December 31, 2022, the Company processed or shipped cement from 14 properties in two states, of which 7 are located on land owned by the Company free of major encumbrances, 1 is located on land owned in part and leased in part and 6 are

on leased land. The Company’s cement operations have production facilities located at three sites: Midlothian, Texas, south of Dallas/Fort Worth; Hunter, Texas, north of San Antonio; and Tehachapi, California. Tehachapi was acquired on October 1, 2021 in connection with the Lehigh Hanson West Region acquisition and is classified as held for sale as of December 31, 2022. The following table summarizes certain information about the Company’s cement manufacturing facilities at December 31, 2022:

Reserves identified with the facilities shown above are contained on approximately 3,000 acres of land owned by the Company. As of December 31, 2022, the Company estimated its total proven and probable limestone reserves on such land to be approximately 717 million tons, which are included in the Summary Mineral Reserves table.

The Company’s cement manufacturing facilities include kilns, crushers, pre-heaters/calciners, coolers, finish mills and other equipment used to process limestone and other raw materials into cement, as well as equipment used to extract and transport the limestone from the adjacent quarries. These cement manufacturing facilities are served by rail and truck.

As of December 31, 2022, the Company also operated, directly or through third parties, 11 cement distribution terminals, of which six are classified as assets held for sale.

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

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

The Company’s principal properties, which are of varying ages and 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 2022, the principal properties of the aggregates operations were believed to be utilized at average productive capacities of approximately 75% and were capable of supporting a higher level of market demand. The Company adjusts its production schedules to meet volume demand for its products.

During 2022, the Texas cement kilns operated on average at 77% utilization. The Portland Cement Association (PCA) has projected that Texas cement consumption will increase 2.0% in 2023 over 2022. The cement business’ leadership, in collaboration with the aggregates and ready mixed concrete teams, has developed strategic plans regarding inter-plant efficiencies, as well as tactical plans addressing plant utilization and efficiency.

The Company’s Magnesia Specialties business expects future organic earnings growth to result from increased pricing, product mix optimization, capacity expansion projects and/or cost reductions. In the current operating environment, where steel utilization is between 72% and 77%, any unplanned change in costs or customers introduces volatility to the earnings of the Magnesia Specialties segment. The dolomitic lime business of the Magnesia Specialties segment operated at 77% utilization in 2022.

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), based upon currently-available facts, it is remote that the ultimate outcome of any litigation and other proceedings will have a material adverse effect on the overall results of the Company's operations, its cash flows or its financial condition. However, management cannot assure 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 2022 for failure to disclose certain “reportable transactions” under Section 6707A of the Internal Revenue Code.

The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K (17 CFR 229.104) is included in Exhibit 95 to this Form 10-K.

ITEM 7 – MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Martin Marietta Materials, Inc. (the Company or Martin Marietta) is a natural resource-based building materials company, with 2022 total revenues of $6.16 billion and 2022 net earnings from continuing operations attributable to Martin Marietta of $856.3 million. These results were achieved in part by supplying aggregates (crushed stone, sand and gravel) through its network of approximately 350 quarries, mines and distribution yards in 28 states, Canada and The Bahamas. Martin Marietta also provides cement and downstream products, namely ready mixed concrete, asphalt and paving services, in certain markets where the Company has a leading aggregates position. Specifically, the Company has two cement plants in Texas, ready mixed concrete operations in Arizona, California and Texas, and asphalt operations in Arizona, California, Colorado and Minnesota. Paving services are offered in California and Colorado. The Company also has one cement plant, related cement distribution terminals and ready mixed concrete operations in California that are classified as assets held for sale and reported as discontinued operations as of and for the years ended December 31, 2022 and 2021.

The Company’s heavy-side building materials are used in infrastructure, nonresidential and residential construction projects. Aggregates are also used in agricultural, utility and environmental applications and as railroad ballast. The aggregates, cement, ready mixed concrete and asphalt and paving product lines are reported collectively as the “Building Materials” business.

As more fully discussed in the Consolidated Strategic Objectives section, geography is critically important for the Building Materials business. The Company conducts its Building Materials business through two reportable segments, organized by geography: East Group and West Group. The East Group, consisting of the East and Central divisions, provides aggregates and asphalt products. The West Group is comprised of the Southwest and West divisions and provides aggregates, cement, downstream products and paving services. Further, the following five states accounted for 64% of the Building Materials business 2022 total revenues: Texas, Colorado, North Carolina, Minnesota and California.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

The Company operates a Magnesia Specialties business with production facilities in Michigan and Ohio. The Magnesia Specialties business produces magnesia-based chemicals products used in industrial, agricultural and environmental applications. It also produces dolomitic lime sold primarily to customers for steel production and soil stabilization. Magnesia Specialties’ products are shipped to customers domestically and worldwide.

The Company’s strategic planning process, or Strategic Operating Analysis and Review (SOAR), provides the framework for execution of Martin Marietta’s long-term strategic plan. Guided by this framework and considering the cyclicality of the Building Materials business, the Company determines capital allocation priorities to maximize long-term shareholder value creation. The Company’s strategy includes ongoing evaluation of aggregates-led opportunities of scale in new domestic markets (i.e., platform acquisitions) and expansion through acquisitions that complement existing operations (i.e., bolt-on acquisitions). To that effect, the Company has invested nearly $8.0 billion in acquisitions since the launch of SOAR in 2010. The Company finances such opportunities with the goal of preserving its financial flexibility by having a leverage ratio (consolidated net debt-to-consolidated earnings before interest, taxes, depreciation, depletion and amortization, or EBITDA) within a range of 2.0 times to 2.5 times within a reasonable period of time, typically within 18 months, following the completion of a debt-financed transaction. SOAR also includes the identification and potential disposition of assets that are not consistent with stated strategic goals. Notably, in 2022, the Company divested its Colorado and Central Texas ready mixed concrete businesses and certain West Coast cement and ready mixed concrete operations, refining its product mix and improving margin profile, while providing balance sheet flexibility.

The Company, by purposeful design, will continue to be an aggregates-led business that focuses on markets with strong, underlying growth fundamentals where it can sustain or achieve a leading market position. In fact, aggregates product gross profit represented 69% of 2022 total consolidated products and services gross profit. As part of its long-term strategic plan, the Company may also pursue strategic cement and targeted downstream opportunities. For Martin Marietta, strategic cement and targeted downstream operations are located in vertically-integrated markets where the Company has, or envisions, among other things, a clear path toward a leading aggregates position.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Generally, the Company’s building materials are both sourced and sold locally. As a result, geography is critically important when assessing market attractiveness and growth opportunities. Attractive geographies generally exhibit (a) population growth and/or high population density, both of which are drivers of heavy-side building materials consumption; (b) business and employment diversity, drivers of greater economic stability; and (c) a superior state financial position, a driver of public infrastructure investment.

Population growth and density are assessed based on a site’s proximity to one of the megaregions in the United States. Megaregions are large networks of metropolitan population centers covering thousands of square miles. According to America 2050, a planning and policy program of the Regional Plan Association, a majority of the nation’s population and economic growth through 2050 will occur in 11 megaregions. The Company has a meaningful presence in ten of the megaregions. As evidence of the successful execution of SOAR, the Company’s leading positions in the Texas Triangle, Colorado’s Front Range, northern and southern California and Arizona’s Sun Corridor megaregions, its growth platform in the southern portion of the Northeast megaregion and its enhanced position in the Piedmont Atlantic megaregion, primarily in the Atlanta area, are the results of acquisitions since 2011. The Company has a legacy presence in the southeastern portion of the Great Lakes megaregion, encompassing operations in Indiana and Ohio, as well as the Florida megaregion and the Gulf Coast megaregion in Texas.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

With respect to business and employment diversity, the Company focuses its geographic footprint along significant transportation and commerce corridors, particularly where land is readily available for the development of fulfillment and/or data centers. The retail sector (both e-commerce and brick and mortar) values transportation corridors, as logistics and distribution are critical considerations for construction supporting that industry. In addition, technology companies view these areas as attractive locations for data centers.

The Company considers a state’s financial health rating, as issued by S&P Global Ratings, in determining the opportunities and attractiveness of areas for expansion or development. The Company’s top ten revenue-generating states have been evaluated and scored a financial health rating of AA- or higher, where AAA is the highest score. The Company also reviews the state’s ability to secure additional infrastructure funding and financing.

In line with the Company’s strategic objectives, management’s overall focus includes:

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

The Company achieved record total revenues, products and services revenues, consolidated gross profit and Adjusted EBITDA (defined in Results of Operations section), benefiting from double-digit pricing growth across all product lines of the Building Materials business and contributions from acquired operations, which more than offset increased inflationary pressure from rising input costs and divestiture impacts on an absolute basis. Further, 2022 represented the eleventh consecutive year of annual growth for products and services revenues, adjusted gross profit and Adjusted EBITDA. The Company’s commitment to safety and operational and commercial excellence resulted in the following financial performance from continuing operations (comparisons with 2021):

The Building Materials business serves customers in the construction marketplace. The business’ profitability is sensitive to national, regional and local economic conditions and cyclical swings in construction spending, which are affected by fluctuations in levels of public-sector infrastructure funding; interest rates; access to capital markets; and demographic, geographic, employment and population dynamics.

The heavy-side construction business, inclusive of much of the Company’s operations, is conducted outdoors. Therefore, erratic weather patterns, precipitation and other weather-related conditions, including flooding, hurricanes, cold temperatures, earthquakes, droughts and wildfires, can significantly affect production schedules, shipments, costs, efficiencies and profitability. Generally, the financial results for the first and fourth quarters are most subject to the impacts of winter weather, while the second and third quarters can be subject to the impacts of heavy precipitation. The impacts of erratic weather patterns are more fully discussed in the Building Materials Business’ Key Considerations section.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Aggregates are an engineered, granular material consisting of crushed stone, sand and gravel, manufactured to specific sizes, grades and chemistry for use primarily in construction applications. The Company’s operations consist mostly of open pit quarries; however, the Company is also the largest operator of underground aggregates mines in the United States, with 14 active underground mines located in the East Group. The Company’s aggregates reserves average approximately 75 years at the 2022 annual production level.

Cement is the basic agent used to bind coarse aggregates, sand and water in the production of ready mixed concrete. The Company has a strategic and leading cement position in the state of Texas, with production facilities in Midlothian, Texas, south of Dallas/Fort Worth, and Hunter, Texas, centrally located along I-35 between San Antonio and Austin. These two facilities produce Portland limestone and specialty cements, have a combined annual capacity of approximately 4.5 million tons and collectively operated at approximately 77% utilization for clinker production in 2022; clinker is the initial product of cement production. The Midlothian plant has a permit that allows for annual capacity expansion of 0.8 million tons. The Company is currently undertaking a finishing capacity expansion project at the Midlothian plant, which is expected to be completed in the middle of 2024 and will provide 0.5 million tons of incremental annual capacity. Further, the Company is nearing completion of converting its plants to manufacture a less carbon-intensive Portland limestone cement, known as Type 1L, that has been approved by the Texas Department of Transportation. In addition to the two production facilities, the Company operates several cement distribution terminals.

Calcium carbonate in the form of limestone is the principal raw material used in the production of cement. The Company owns more than 600 million tons of limestone reserves adjacent to its cement production plants in Texas. During 2021, the Company purchased two cement plants in Redding and Tehachapi, California, and related distribution facilities as part of the acquisition of Lehigh Hanson, Inc.'s West Region business (Lehigh West Region). The Redding plant and related distribution terminals were sold on June 30, 2022. The Tehachapi plant and related distribution terminals were classified as assets held for sale and discontinued operations as of and for the years ended December 31, 2022 and 2021. In August 2022, the Company announced a definitive agreement to sell the Tehachapi plant and related distribution terminals, subject to regulatory approval and customary closing conditions.

Asphalt is most commonly used in surfacing roads and parking lots and consists of liquid asphalt, or bitumen, the binding medium, and aggregates. Similar to ready mixed concrete, each asphalt batch is produced to customer specifications. The Company’s asphalt operations are located in Arizona, California, Colorado and Minnesota and paving services are offered in California and Colorado. Market dynamics for these downstream product lines include a highly competitive environment and lower barriers to entry compared with the Company’s upstream product lines of aggregates and cement.

The principal end-use markets of the Building Materials business are public infrastructure (i.e., highways; streets; roads; bridges; and schools); nonresidential construction (i.e., manufacturing and distribution facilities; industrial complexes; office

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

buildings; large retailers and wholesalers; healthcare; hospitality; and energy-related activity); and residential construction (i.e., subdivision development; and single- and multi-family housing). Aggregates are also used in agricultural, utility and environmental applications and as railroad ballast, collectively comprising the ChemRock/Rail market.

Public infrastructure projects can require several years to complete, while residential and nonresidential construction projects are usually completed within one year. Generally, customer purchase orders do not contain firm quantity commitments, regardless of end-use market. Therefore, management does not utilize a Company backlog in managing its business.

The public infrastructure market accounted for 35% of the Company’s aggregates shipments in 2022, a 5% volume increase from 2021 as a result of solid demand spurred by accelerating federal and state level investment. The Company’s shipments to this end-use market remain below the most recent five-year average of 36% and ten-year average of 39%.

Public construction projects, once awarded, are typically seen through to completion. Thus, delays from weather or other factors can serve to extend the duration of the construction cycle. While construction spending in the public and private market sectors is affected by economic cycles, public infrastructure spending has been comparatively more stable due to the predictability of funding from federal, state and local governments. The Infrastructure Investments and Jobs Act (IIJ Act) was signed into law on November 15, 2021 and contains a five-year surface transportation reauthorization plus $110 billion in new funding for roads, bridges and other hard infrastructure projects.

State and local initiatives that support infrastructure funding, including gas tax increases and other ballot initiatives, are increasing in size and number as these governments recognize the need for their expanded role in public infrastructure funding. In November 2022, 411 state and local ballot initiatives, or 87% of all infrastructure funding measures up for vote, were approved. These approved infrastructure initiatives are estimated to generate nearly $23 billion in one-time and recurring revenues, with initiatives in Texas, the Company’s largest revenue-generating state, accounting for over $15 billion of this total.

The nonresidential construction market accounted for 36% of the Company’s aggregates shipments in 2022, a 3% volume increase over 2021, reflecting several large warehouse projects. Large industrial projects of scale led by energy, onshore manufacturing and data centers continue to lead the segment, accounting for the majority of total nonresidential shipments. Over the medium term, the Company expects enhanced federal investment from the Inflation Reduction Act and Creating Helpful Incentives to Produce Semiconductors Act will further support and accelerate post-pandemic secular growth trends, including restructured manufacturing and energy supply chains, electric vehicle transition and continued adoption of digital and cloud-based technologies, resulting in robust demand within the heavy nonresidential sector. The Dodge Momentum Index, a twelve-month leading indicator of construction spending for nonresidential building compiled by Dodge Construction Network, was 222.2 in December 2022, where the year 2000 serves as an index basis of 100. This represented an increase of 40% from December 2021, further suggesting positive momentum in the nonresidential construction sector at the onset of 2023.

The residential construction market accounted for 24% of the Company’s aggregates shipments in 2022 and was flat compared with strong 2021 activity. This end use typically moves in direct correlation with economic cycles. The Company’s exposure to residential construction is split between aggregates used in the construction of subdivisions (including streets, sidewalks, utilities and storm and sewage drainage), single-family homes and multi-family units. Construction of both subdivisions and single-family homes is nearly three times more aggregates intensive than construction of multi-family units. Therefore, the level of new subdivision starts, as well as new single-family housing permits, is a strong leading indicator of residential volumes. For the year ended December 31, 2022, not seasonally adjusted national housing starts decreased 3% to 1.55 million units compared with 2021 and not seasonally adjusted national housing permits decreased 5% versus 2021. Despite overall underbuilt conditions, several of the Company's markets experienced a slowdown in single-family demand due to affordability concerns, increased interest rates and logistical challenges.

The remaining 5% of the Company’s 2022 aggregates shipments was to the ChemRock/Rail market, which includes ballast and agricultural limestone. Ballast is an aggregates product used to stabilize railroad track beds. Agricultural lime, a high-calcium

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

carbonate material, is used as a supplement in animal feed, a soil acidity neutralizer and agricultural growth enhancer. Additionally, ChemRock/Rail includes rip rap, which is used as a stabilizing material to control erosion caused by water runoff at embankments, ocean beaches, inlets, rivers and streams, and high-calcium limestone, which is used as filler in glass, plastic, paint, rubber, adhesives, grease and paper. Chemical-grade, high-calcium limestone is used as a desulfurization material in utility plants.

Materials pricing for construction projects is generally based on terms committing to the availability of specified products of a stated quantity at an agreed-upon price during a definitive period. Since infrastructure projects span multiple years, announced price changes can have a lag time before taking effect while the Company sells products under existing price agreements. Pricing escalators included in multi-year infrastructure contracts serve to somewhat mitigate this effect. However, during periods of sharp or rapid increases in production costs, multi-year infrastructure contract pricing may provide only nominal pricing growth. Additionally, the Company may implement multiple price increases throughout the year, on a market-by-market basis, where appropriate, as was done in 2022. Pricing is determined locally and is affected by supply and demand characteristics of the local market. For further information on pricing, see the discussion in the Financial Overview section.

Costs of revenues for the Building Materials business are components of costs incurred at the quarries, mines, cement plants, ready mixed concrete plants, asphalt plants, paving operations and distribution yards and facilities. Cost of revenues also includes the cost of resale materials, freight expenses to transport materials from a producing quarry or cement plant to a distribution yard or facility and production overhead costs.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Generally, the significant components of costs of revenues for the aggregates product line are (1) labor and related benefits; (2) internal freight; (3) depreciation, depletion and amortization; (4) repairs and maintenance; (5) energy; (6) supplies; and (7) contract services. In 2022, these categories represented 82% of the aggregates product line's total costs of revenues.

Variable costs are expenses that fluctuate with the level of production volume, while fixed costs are expenses that do not vary based on production or sales volume. Production is the key driver in determining the levels of variable costs, as it affects the number of hourly employees and related labor hours. Further, components of energy, supplies and repairs and maintenance costs also increase in connection with higher production volumes. Accordingly, the Company’s operating leverage can be substantial.

Generally, when the Company invests capital in facilities and equipment, increased capacity and productivity reduce labor and repair costs, and can offset increased fixed depreciation costs. However, the increased productivity and related efficiencies may not be fully realized in a lower-demand environment, resulting in under-absorption of fixed costs.

Wage and benefit inflation and other increases in labor costs may be somewhat mitigated by enhanced productivity in an expanding economy. Further, workforce reductions resulting from process automation and mobile fleet right-sizing, primarily in the aggregates operations, have mitigated rising labor costs. During economic downturns, the Company reviews its operations and, where practical, temporarily idles certain sites. The Company is able to serve these markets with other open facilities that are in close proximity. In certain markets, management can create production “super crews” that work on a rotating basis at various locations. For example, within a market, a crew may work three days per week at one quarry and the other two workdays at another quarry. This has allowed the Company to responsibly manage headcount in periods of lower demand.

Cement production is a capital-intensive operation with high fixed costs to run plants that operate continuously with the exception of maintenance shutdowns. Kiln and finishing mill maintenance typically requires a plant to be shut down for a period of time as repairs are made. In 2022 and 2021, the cement operations incurred outage costs of $33.3 million and $23.6 million, respectively. The increase in outage costs in 2022 compared with 2021 is primarily attributable to the timing of planned and unplanned kiln outages. The Company adjusts production levels in anticipation of planned maintenance shutdowns.

The production of ready mixed concrete and asphalt requires the use of cement and liquid asphalt raw materials, respectively. Therefore, fluctuations in availability and prices for these raw materials directly affect the Company’s operating results.

Typically, diesel fuel represents the single-largest component of energy costs for the Building Materials business. The average cost per gallon was $4.01 and $2.36 in 2022 and 2021, respectively. Changes in energy costs also affect the prices that the Company pays for related supplies, including explosives, conveyor belting and tires. Further, the Company’s contracts of affreightment for shipping products on its rail and waterborne distribution network typically include provisions for escalations or reductions in the amounts paid by the Company if the price of fuel moves outside a stated range.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Growth markets with limited supply of indigenous stone must be served via a long-haul distribution network

The U.S. Department of the Interior identified possible sources of indigenous rock and documented its limited supply in certain areas of the United States, including the coastal areas from Virginia to Texas. Further, certain interior United States markets may experience limited availability of locally sourced aggregates resulting from increasingly restrictive zoning, permitting and/or environmental laws and regulations. The Company’s long-haul distribution network is used to supplement, or in many cases, wholly supply, the local crushed stone needs of these areas.

The long-haul distribution network can also diversify market risk for locations that engage in long-haul transportation of aggregates products. This is particularly true where a producing quarry serves a local market and transports products via rail, water and/or truck to be sold in other markets. The risk of a downturn in one market may be somewhat mitigated by other markets served by the location.

Product shipments are moved by rail, water and truck through the Company’s long-haul distribution network. The Company’s rail network primarily serves its Texas, Florida, Colorado and Gulf Coast markets, while the Company’s Bahamas and Nova Scotia locations transport materials via oceangoing ships. The Company’s strategic focus includes expanding inland and offshore capacity and acquiring distribution yards and port locations to offload transported material. At December 31, 2022, the distribution network available to the Company consisted of 78 aggregates yards and 11 cement terminals, of which six cement terminals were classified as discontinued operations.

The Company’s increased rail shipments have made it more reliant on railroad operations, including track congestion, crew and locomotive availability, the effects of adverse weather conditions and the ability to negotiate favorable railroad shipping contracts. Further, changes in the operating strategy of rail transportation providers can create operational inefficiencies and increased costs from the Company’s rail network.

A portion of railcars and all ships of the Company’s long-haul distribution network are under short- and long-term leases, some with purchase options, and contracts of affreightment. The limited availability of water and rail transportation providers, coupled with limited distribution sites, can adversely affect lease rates for such services and ultimately the freight rates.

The Company has long-term agreements providing dedicated shipping capacity from its Bahamas and Nova Scotia operations to its coastal ports. These contracts of affreightment are take-or-pay contracts with minimum and maximum shipping requirements. The minimum requirements were met in 2022. The Company’s waterborne contracts of affreightment have varying expiration dates ranging from 2023 to 2027 and generally contain renewal options. However, there can be no assurance that such contracts can be renewed upon expiration or that terms will continue without significant increases.

The multiple transportation modes that have been developed with various rail carriers and deep-water ships provide the Company with the flexibility to effectively serve customers primarily in the Southwest and Southeast coastal markets.

Public infrastructure, historically, the Company’s largest end-use market, is funded through a combination of federal, state and local sources

Transportation investments generally boost the national economy by enhancing mobility and access and creating jobs, which are priorities of many of the government’s economic plans. Public-sector construction related to transportation infrastructure is funded through a combination of federal, state and local sources. The federal highway bill, currently the IIJ Act, provides annual funding for public-sector highway construction projects and includes spending authorizations, which represent the maximum financial obligation that will result from the immediate or future outlays of federal funds for highway and transit programs. The federal government’s surface transportation programs are funded mostly through the receipts of highway user taxes placed in the Highway Trust Fund, which is divided into the Highway Account and the Mass Transit Account. Revenues credited to the Highway Trust Fund are primarily derived from a federal gas tax, a federal tax on certain other motor fuels and interest on the accounts’ accumulated balances. Of the currently imposed federal gas tax of $0.184 per gallon, which has been static since 1993, $0.15 is allocated to the Highway Account of the Highway Trust Fund.

Since most states are required to balance their budgets, reductions in revenues generally require a reduction in states’ expenditures. However, the impact of state revenue reductions on highway investment will vary depending on whether the monies come from dedicated revenue sources, such as highway user fees, or whether portions are paid for with general funds.

In addition to federal appropriations, each state typically funds its infrastructure investment from specifically allocated amounts collected from various user fees, typically gasoline taxes and vehicle fees. Over the past several years, states have assumed a significantly larger role in funding infrastructure investment, including initiating special-purpose taxes and raising gas taxes. Management believes that financing at the state and local levels, such as bond issuances, toll roads, vehicle miles traveled fees and tax initiatives, will continue to grow and have a fundamental role in advancing infrastructure projects. State infrastructure investment generally leads to increased growth opportunities for the Company. The level of state public-works spending is varied across the nation and dependent upon individual state economies, and the degree to which the Company could be affected by a reduction or slowdown in infrastructure spending varies by state. The state economies of the Building Materials business’ ten largest revenue-generating states may disproportionately affect the Company’s financial performance.

Governmental appropriations and expenditures are typically less interest rate-sensitive than private-sector spending. Obligations of federal funds are a leading indicator of highway construction activity in the United States. Before a state or local department of transportation can solicit bids on an eligible construction project, it enters into an agreement with the Federal Highway Administration to obligate the federal government to pay its portion of the project cost. Federal obligations are subject to annual funding appropriations by Congress.

The need for surface transportation improvements continues to significantly outpace the amount of available funding. A large number of roads, highways and bridges built following the establishment of the Interstate Highway System in 1956 now require major repair or reconstruction. According to the latest information available from The Road Information Program (TRIP), a national transportation research group, vehicle travel on the nation's roads increased 26% from 2000 to 2019, while new lane road mileage increased only 9% over the same period. TRIP also reports that 40% of the nation’s major roads are in poor or mediocre condition, while 7% of the nation’s bridges are in poor/structurally deficient condition. Additionally, there is an estimated backlog of $123 billion of improvements to the nation’s highway system that requires an increase in annual investment of $23 billion to $57 billion for the next 20 years to address these improvements and meet mobility and modernization needs. Management believes infrastructure activity for 2023 and beyond should benefit from the IIJ Act and additional state and local infrastructure initiatives.

In addition to highways and bridges, transportation infrastructure includes aviation, mass transit, and ports and waterways. Railroad construction continues to benefit from economic growth, which ultimately generates a need for additional maintenance and improvements.

Production and shipment levels for the Building Materials business correlate with general construction activity, most of which occurs outdoors and, as a result, is affected by erratic weather, seasonal changes and other climate-related conditions. Typically, due to a general slowdown in construction activity during winter months, the first and fourth quarters experience lower production and shipment activity. As such, temperatures in the months of March and November can meaningfully affect

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

the Company’s first- and fourth-quarter results, respectively, where warm and/or moderate temperatures in March and November allow the construction season to start earlier and end later, respectively.

Excessive rainfall jeopardizes production efficiencies, shipments and profitability in all markets served by the Company. In particular, the Company’s operations in the southeastern and Gulf Coast regions of the United States and The Bahamas are at risk for hurricane activity from June 1 through November 1, but most notably in August, September and October. The Company’s California operations are at risk for wildfire activity and water use restrictions in severe drought conditions. Increased intensity and frequency of extreme weather events have been linked to climate change, and further global warming may increase the risk of adverse weather conditions.

Capital investment decisions driven by capital intensity of the Building Materials business and focus on land

The Company’s organic capital program is designed to leverage construction market growth through investment in both permanent and portable facilities at the Company’s operations. Over an economic cycle, the Company typically invests organic capital at an annual level that approximates depreciation expense. At mid-cycle and through cyclical peaks, organic capital investment typically exceeds depreciation expense, as the Company supports current capacity needs and future growth. Conversely, at a cyclical trough, the Company may reduce levels of capital investment. Regardless of cycle, the Company sets a priority of investing capital to ensure safe, environmentally-sound and efficient operations, as well as to provide the highest quality of customer service and establish a foundation for future growth.

The Company is diligent in its focus on land opportunities, including potential new sites (greensites) and existing site expansion. Land purchases are usually opportunistic and can include contiguous property around existing quarry locations. Such property can serve as buffer property or additional mineral reserves, assuming regulatory hurdles can be cleared and the underlying geology supports economical aggregates mining. In either instance, the acquisition of additional property around an existing quarry typically allows the expansion of the quarry footprint and an extension of quarry life.

The Magnesia Specialties business manufactures magnesia-based chemicals products for industrial, agricultural and environmental applications at its Manistee, Michigan facility. The Magnesia Specialties business produces and sells dolomitic lime from its Woodville, Ohio facility. Of 2022 total Magnesia Specialties revenues, 72% was attributable to chemicals products, 27% was attributable to lime and 1% was attributable to stone.

In 2022, 74% of lime shipments was sold to third-party customers, while the remaining 26% was used internally as a raw material for the manufacturing of chemicals products. Dolomitic lime products sold to external customers are primarily used by the domestic steel industry and, overall, 31% of Magnesia Specialties’ 2022 total revenues was related to products used in the steel industry. Accordingly, a portion of the segment’s revenues and profits is affected by production and inventory trends within the steel industry, which are guided by the rate of consumer consumption, the flow of offshore imports and other economic factors. Domestic steel production averaged 81% of capacity in 2021, but declined in 2022, averaging 75%. The

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

dolomitic lime business runs most profitably at 70% or greater steel capacity utilization. The chemical products business focuses on higher-margin specialty chemicals that can be produced at volumes that support efficient operations.

Total revenues of the Magnesia Specialties business were predominantly derived from domestic customers in 2022. Financial results can be affected by foreign currency exchange rates, increasing transportation costs or weak economic conditions in foreign markets. To mitigate the short-term effect of currency exchange rates, foreign transactions are denominated in United States dollars.

A significant portion of the Magnesia Specialties business’ costs is of a fixed or semi-fixed nature. The production process requires the use of natural gas, coal and petroleum coke; therefore, fluctuations in their pricing directly affect operating results. To help mitigate this risk, the Company has fixed-price agreements for approximately 39% of its 2023 energy needs for coal and natural gas. For 2022, the segment’s average cost per MMBtu (1,000,000 British thermal units) of natural gas increased 47% versus 2021. Given high fixed costs, low capacity utilization can negatively affect the segment’s results of operations. Management expects future organic profitability growth to result from increased pricing, rationalization of the current product portfolio and/or further cost reductions.

The Magnesia Specialties business is highly dependent on rail transportation, particularly for movement of dolomitic lime from Woodville to Manistee and direct customer shipments of dolomitic lime and magnesia chemicals products from both Woodville and Manistee. The segment can be affected by the risks mentioned in the long-haul distribution discussion in the Building Materials Business’ Key Considerations section.

The expansion and growth of the aggregates industry is subject to increasing challenges from environmental and political advocates aiming to control the pace and direction of future development. Certain environmental groups have published lists of targeted municipal areas, including areas within the Company’s marketplace, for environmental and suburban growth control. The effect of these initiatives on the Company’s growth is typically localized. Further challenges are expected as the momentum of these initiatives ebb and flow across the United States. Rail and other transportation alternatives are being heralded by these special-interest groups as solutions to mitigate road traffic congestion and overcrowding.

The Company’s operations are subject to and affected by federal, state and local laws, rules and regulations relating to the environment, health and safety and other regulatory matters. Certain of the Company’s operations may occasionally use substances classified as toxic or hazardous. The Company regularly monitors and reviews its operations, procedures and policies for compliance with these laws and regulations. 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.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Environmental operating permits are, or may be, required for certain of the Company’s operations; such permits are subject to modification, renewal and revocation. New permits are generally required for opening new sites or for expansion at existing operations and can take several years to obtain. Moreover, land use, rezoning and special or conditional use permits are increasingly difficult to obtain. Once a permit is issued, the location is required to generally operate in accordance with the approved site plan.

The Clean Air Act, originally passed in 1963 and periodically updated by amendments, is the United States’ national air pollution control program that granted the Environmental Protection Agency (EPA) authority to set limits on the level of various air pollutants. To be in compliance with National Ambient Air Quality Standards, a defined geographic area must be below established limits for six pollutants. Environmental groups have been successful in lawsuits against the federal and certain state departments of transportation, delaying highway construction in municipal areas not in compliance with the Clean Air Act. The EPA designates geographic areas as nonattainment areas when the level of air pollutants exceeds the national standard. Nonattainment areas receive deadlines to reduce air pollutants by instituting various control strategies or otherwise face fines or control by the EPA. Included as nonattainment areas are several major metropolitan areas in the Company’s markets, such as Houston/Brazoria/Galveston, Texas; Dallas/Fort Worth, Texas; Bexar County in San Antonio/New Braunfels, Texas; Denver, Colorado; Boulder, Colorado; Fort Collins/Greeley/Loveland, Colorado; Atlanta, Georgia; Baltimore, Maryland; Los Angeles-San Bernardino Counties, California; Los Angeles – South Coast Basin, California; Phoenix/Mesa, Arizona; San Diego County, California; San Francisco Bay Area, California; San Joaquin Valley, California; and Sacramento County, California. Federal transportation funding has been directly tied to compliance with the Clean Air Act.

Large emitters (facilities that emit 25,000 metric tons or more per year) of greenhouse gases (GHG) must report GHG generation to comply with the EPA’s Mandatory Greenhouse Gases Reporting Rule (GHG Rule). The Company files annual reports in accordance with the GHG Rule relating to operations at its three cement plants in Texas and California, as well as its Magnesia Specialties facilities in Woodville, Ohio, and Manistee, Michigan, each of which emit certain GHG, including carbon dioxide, methane and nitrous oxide. If Congress passes additional legislation limiting GHG emissions, these operations will likely be subject to such legislation. The Company believes that any increased operating costs or taxes related to GHG emission limitations at its cement or Woodville operations would be passed on to its customers. The Manistee facility may have to absorb extra costs due to the regulation of GHG emissions in order to maintain competitive pricing in its markets. The Company cannot reasonably predict how much those increased costs may be.

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

In 2022, the Company achieved its eleventh consecutive year of growth for consolidated products and services revenues, gross profit and Adjusted EBITDA. This section presents metrics for continuing operations.

The discussion and analysis that follow reflect management’s assessment of the financial condition and results of operations (MD&A) of the Company and should be read in conjunction with the audited consolidated financial statements. As discussed in more detail, the Company’s operating results are highly dependent upon activity within the construction marketplace, economic cycles within the public and private business sectors, and seasonal and other weather-related conditions. Accordingly, financial results for any year presented, or year-to-year comparisons of reported results, may not be indicative of future operating results. As permitted by the Securities and Exchange Commission (SEC) under the FAST Act Modernization and Simplification of Regulation S-K, the Company has elected to omit the discussion of the earliest period (2020) presented as it was included in its MD&A in its 2021 Form 10-K filed on February 22, 2022, incorporated by reference from Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” thereto.

The Company’s Building Materials business generated the majority of consolidated total revenues and earnings from continuing operations. The following comparative analysis and discussion should be read within this context. Further, sensitivity analysis and certain other data are provided to enhance the reader’s understanding of MD&A and are not intended to be indicative of management’s judgment of materiality.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

The Company’s consolidated operating results and operating results as a percentage of total revenues are as follows:

Earnings from continuing operations before interest; income taxes; depreciation, depletion and amortization; earnings/loss from nonconsolidated equity affiliates; acquisition and integration expenses; the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting; and the nonrecurring gain on the divestiture of certain ready mixed concrete operations (Adjusted EBITDA) is an indicator used by the Company and investors to evaluate the Company’s operating performance from period to period. Adjusted EBITDA is not defined by generally accepted accounting principles (GAAP) and, as such, should not be construed as an alternative to net earnings attributable to Martin Marietta, earnings from operations or operating cash flow. However, the Company’s management believes that Adjusted EBITDA may provide additional information with respect to the Company’s performance. Since Adjusted EBITDA excludes some, but not all, items that affect net earnings and may vary among companies, Adjusted EBITDA as presented by the Company may not be comparable to similarly titled measures of other companies.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following table presents a reconciliation of net earnings from continuing operations attributable to Martin Marietta to consolidated Adjusted EBITDA:

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Mix-adjusted average selling price (mix-adjusted ASP) is a non-GAAP measure that excludes the impacts of period-over-period product, geographic and other mix on the average selling price. Mix-adjusted ASP is calculated by comparing current-period shipments to like-for-like shipments in the comparable prior period. Management uses this metric to evaluate the realization of pricing increases and believes this information is useful to investors. The following reconciles reported average selling price to mix-adjusted ASP and corresponding variances:

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following table presents revenues data for the Company and its reportable segments by product line:

The following table presents gross profit and gross margin data for the Company by product line:

The increase in Building Materials business gross profit in 2022 compared with 2021 was primarily attributable to pricing growth and the accretive impacts of acquisitions, which more than offset historically high cost inflation and the divestiture of the Colorado and Central Texas ready mixed concrete operations on an absolute basis. The Building Materials business gross margin was negatively impacted by inflationary cost increases throughout the year. While pricing increases were implemented during

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

the year, the full benefits are achieved over time as existing contracts are replaced with new contracts with updated pricing. The decrease in gross profit in Magnesia Specialties was driven by lower demand from domestic steel industry customers for dolomitic lime products and higher energy and contract services costs.

Corporate gross profit includes intercompany royalty and rental revenue and expenses, depreciation and unallocated operational expenses excluded from the Company’s evaluation of business segment performance.

Aggregates. The average selling price per ton for aggregates was $16.68 and $15.08 for 2022 and 2021, respectively.

Aggregates average selling price increases compared to the prior year are as follows:

Aggregates pricing improved 10.6%, or 10.0% on a mix-adjusted basis, compared with 2021. The East Group reported an increase of 10.5%, or 9.3% on a mix-adjusted basis, and West Group pricing increased 11.9%, or 11.4% on a mix-adjusted basis, compared with 2021, reflecting multiple price actions implemented throughout the year.

The following presents aggregates shipments for each reportable segment of the Building Materials business:

Aggregates shipments sold to external customers and internal tons used in other product lines are as follows:

Aggregates volume variance compared to the prior year by reportable segment is as follows:

Aggregates volume increased in 2022, benefiting from contributions from acquired operations and solid construction activity across all three primary end-use markets.

Cement, Ready Mixed Concrete, Asphalt and Paving Services. Average selling prices for cement, ready mixed concrete and asphalt are as follows:

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Cement shipments increased 4.7% in 2022 versus prior year from continued strong demand and tight supply in North and South Texas. Cement pricing improved 16.9%, or 16.5% on a mix-adjusted basis, compared with the prior year, driven by the impact of multiple price increases during the year. Cement product gross margin expanded 210 basis points, as shipment and pricing growth more than offset higher energy, maintenance and raw materials costs.

Ready mixed concrete shipments decreased 25.4%, primarily reflecting the impact of divested operations, partially offset by the acquired Arizona operations and pricing increased 11.3%. In 2022, asphalt pricing increased 23.6% primarily attributable to price increases implemented throughout the year, following increases in raw material costs, while volumes improved 28.4%, driven by shipments from the acquired Lehigh West Region operations.

Magnesia Specialties. In 2022, Magnesia Specialties reported total revenues of $304.0 million, gross profit of $90.9 million and earnings from operations of $75.2 million, representing an increase of 1.8%, a decrease of 14.7% and a decrease of 17.1%, respectively, compared with 2021. The profitability decreases in 2022 were reflective of lower domestic steel production and demand for chemicals products, coupled with higher energy and maintenance costs.

SG&A expenses for 2022 and 2021 were 6.4% and 6.5% of total revenues, respectively. The $45.7 million increase in total expense was primarily driven by a full year of expense for operations acquired in 2021.

The Company incurred $57.9 million of acquisition and integration expenses in 2021, primarily associated with the Tiller and Lehigh West Region acquisitions.

Other operating income, net, is comprised generally of gains and losses on the sale of assets; recoveries and losses related to certain customer accounts receivable; rental, royalty and services income; accretion expense, depreciation expense and gains and losses related to asset retirement obligations. These net amounts represented income of $189.2 million in 2022 and $34.3 million in 2021. In 2022, other operating income, net, included a $151.9 million pretax gain on the divestiture of the Colorado and Central Texas ready mixed concrete operations. For 2021, other operating income, net, included $21.6 million of nonrecurring gains on land sales and divested assets driven primarily by the sale of the Company’s former corporate headquarters.

Consolidated earnings from operations were $1.21 billion and $973.8 million in 2022 and 2021, respectively.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Interest expense was $169.0 million in 2022 and $142.7 million in 2021. The increase reflected a full-year of interest on the $2.5 billion of publicly traded debt the Company issued in July 2021 to help finance acquisition activity.

Other nonoperating income, net, is comprised generally of interest income; foreign currency transaction gains and losses; pension and postretirement benefit cost (excluding service cost); net equity earnings from nonconsolidated investments and other miscellaneous income and expenses. Consolidated other nonoperating income, net, was $53.4 million in 2022 and $24.4 million in 2021. Other nonoperating income, net, for the year ended December 31, 2022 included a $12.0 million pretax gain related to the repurchase of the Company's debt, $8.2 million of third-party railroad track maintenance expense and a $13.3 million increase in interest income.

Variances in the estimated effective income tax rates, when compared with the statutory corporate income tax rate, are due primarily to the statutory depletion deduction for mineral reserves, the effect of state income taxes, stock compensation deductions, and the impact of foreign income or losses for which no tax expense or benefit is recognized. Additionally, certain acquisition-related expenses have limited deductibility for income tax purposes.

The permanent benefit associated with the statutory depletion deduction for mineral reserves is typically the significant driver of the estimated effective income tax rate. The statutory depletion deduction is calculated as a percentage of revenues subject to certain limitations. Due to these limitations, changes in sales volumes and pretax earnings may not proportionately affect the statutory depletion deduction and the corresponding impact on the effective income tax rate. However, the impact of the depletion deduction on the estimated effective tax rate is inversely affected by increases or decreases in pretax earnings.

The Company’s estimated effective income tax rate for the years ended December 31, 2022 and 2021 was 21.5% and 17.9%, respectively. The higher 2022 effective income tax rate versus 2021 was primarily driven by the impact of the divestiture of the Colorado and Central Texas ready mixed concrete businesses.

The effective income tax rate for 2022 and 2021 included a $10.3 million and $9.7 million discrete benefit from financing third-party railroad track maintenance, respectively. In exchange, the Company received a federal income tax credit and deduction.

The Company classified its Tehachapi cement plant, related cement terminals and its California ready mixed concrete businesses acquired as part of Lehigh West Region as assets held for sale and discontinued operations as of and for the years ended December 31, 2022 and 2021. Additionally, the Redding cement plant, related cement terminals and 14 ready mixed concrete plants that were classified as discontinued operations as of and for the year ended December 31, 2021 were sold in June 2022. The collective businesses generated earnings of $10.5 million and $0.5 million, respectively, net of expenses associated with the planned disposal, the impact of selling acquired inventory after its step up to fair value as part of acquisition accounting and income tax expense.

Net earnings from continuing operations attributable to Martin Marietta were $856.3 million, or $13.70 per diluted share, for 2022 and $702.0 million, or $11.21 per diluted share, for 2021.

Generally, the Company’s primary source of liquidity is cash generated from operating activities. Operating cash flow is substantially derived from consolidated net earnings, before deducting depreciation, depletion and amortization, and offset by working capital requirements. Cash provided by operations was $991.2 million in 2022 and $1.14 billion in 2021. The primary drivers of the decrease in cash provided by operations in 2022 were increased cash taxes and changes in working capital.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Net cash used for investing activities was $483.8 million in 2022 and $3.47 billion in 2021. The decrease reflected lower acquisition activity in 2022 compared with $3.11 billion used to consummate acquisitions during 2021.

Cash paid for property, plant and equipment additions was $481.8 million in 2022 and $423.1 million in 2021.

Pretax proceeds from divestitures and sales of assets were $687.1 million in 2022 and $42.8 million in 2021.

The Company invested $704.6 million in restricted investments to satisfy discharged debt and related interest (see Capital Structure and Resources section).

Net cash used for financing activities was $407.5 million in 2022 compared with net cash provided by financing activities of $2.29 billion in 2021. The 2021 cash provided reflected the issuance of $2.50 billion in publicly traded debt, primarily to finance acquisitions.

During 2022, the Company repurchased $67.7 million (par value) of its Senior Notes, resulting in a pretax gain of $12.0 million.

For the years ended December 31, 2022 and 2021, the Board of Directors approved total cash dividends on the Company’s common stock of $2.54 per share and $2.36 per share, respectively. Total cash dividends paid were $159.1 million in 2022 and $147.8 million in 2021.

In 2022, the Company repurchased 0.4 million shares of its common stock for a total cost of $150.0 million, or $358.56 per share.

Long-term debt, including current maturities of discharged debt, was $5.04 billion at December 31, 2022, and was in the form of publicly-issued long-term notes and debentures.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

On September 29, 2022, the Company satisfied and discharged its $700 million of 0.650% Senior Notes due 2023 (the 0.650% Senior Notes), which were issued in July 2021. In connection with the satisfaction and discharge, the Company irrevocably deposited funds in an amount sufficient to satisfy all remaining principal and interest payments on the 0.650% Senior Notes with Regions Bank (the Trustee). The funds are invested in a fund that invests exclusively in U.S. Treasury securities and are classified as Restricted investments (to satisfy discharged debt and related interest) on the consolidated balance sheet at December 31, 2022. Holders of the 0.650% Senior Notes will receive payment of principal on the scheduled maturity date and payment of interest at the per annum rate (and on the dates) set forth in the 0.650% Senior Notes indenture. The Company utilized existing cash resources to fund the satisfaction and discharge. As a result of the satisfaction and discharge, the obligations of the Company under the indenture with respect to the 0.650% Senior Notes have been terminated, except those provisions of the indenture that, by their terms, survive the satisfaction and discharge. The 0.650% Senior Notes remain on the Company’s consolidated balance sheet at December 31, 2022 and will continue to accrete to their par value over the period until maturity in July 2023.

In July 2021, the Company issued the 0.650% Senior Notes, $900.0 million aggregate principal amount of 2.400% Senior Notes due 2031 (the 2.400% Senior Notes) and $900.0 million aggregate principal amount of 3.200% Senior Notes due 2051 (the 3.200% Senior Notes). The Company used the net proceeds to pay the consideration for the acquisition of the Lehigh West Region business and for general corporate purposes. See Note C to the financial statements for more information on the Lehigh West Region acquisition, which was consummated on October 1, 2021.

The Company, through a wholly-owned special-purpose subsidiary, has a $400.0 million trade receivable securitization facility (the Trade Receivable Facility). In September 2022, the Company extended the maturity of the Trade Receivable Facility to September 21, 2023. The Trade Receivable Facility is backed by eligible trade receivables, as defined. Borrowings are limited to the lesser of the facility limit or the borrowing base, as defined. These receivables are originated by the Company and then sold or contributed to the wholly-owned special-purpose subsidiary. The Company continues to be responsible for the servicing and administration of the receivables purchased by the wholly-owned special-purpose subsidiary. The Trade Receivable Facility contains a cross-default provision to the Company’s other debt agreements. Subject to certain conditions, including lenders providing the requisite commitments, the Trade Receivable Facility may be increased to a borrowing base not to exceed $500 million. There were no outstanding borrowings on the Trade Receivable Facility as of December 31, 2022.

The Company has an $800.0 million five-year senior unsecured revolving facility (the Revolving Facility), which matures in December 2027. There were no outstanding borrowings on the Revolving Facility as of December 31, 2022. The Revolving Facility requires the Company’s ratio of consolidated net debt-to-consolidated EBITDA, as defined, for the trailing-twelve months (the Ratio) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Company may exclude from the Ratio debt incurred in connection with certain acquisitions during the quarter or the three preceding quarters so long as the Ratio calculated without such exclusion does not exceed 4.00x. Additionally, if there are no amounts outstanding under the Revolving Facility and the Trade Receivable Facility, consolidated debt, including debt for which the Company is a guarantor, shall be reduced in an amount equal to the lesser of $500.0 million or the sum of the Company’s unrestricted cash and temporary investments, for purposes of the covenant calculation. The Company was in compliance with the Ratio and other requirements under the Revolving Credit Facility at December 31, 2022.

Total equity was $7.17 billion at December 31, 2022. At that date, the Company had an accumulated other comprehensive loss of $38.5 million, primarily resulting from unrecognized prior service cost and actuarial loss related to pension benefits.

Pursuant to authority granted by its Board of Directors, the Company can repurchase up to 20 million shares of common stock. As of December 31, 2022, the Company had 13.1 million shares remaining under the repurchase authorization. Future share repurchases are at the discretion of management.

At December 31, 2022, the Company had $358.0 million in unrestricted cash and short-term investments that are considered cash equivalents. The Company manages its cash and cash equivalents to ensure short-term operating cash needs are met and excess funds are managed efficiently. The Company funds shortages in operating cash through credit facilities. The Company utilizes excess cash to either pay down credit facility borrowings or invest in money market funds, money market demand deposit accounts or Eurodollar time deposit accounts. Money market demand deposits and Eurodollar time deposit accounts are exposed to bank solvency risk. Money market demand deposit accounts are FDIC insured up to $250,000. The Company’s investments in bank funds generally exceed the FDIC insurance limit.

Cash on hand, along with the Company’s projected internal cash flows and availability of financing resources, including its access to debt and equity capital markets, is expected to continue to be sufficient to provide the capital resources necessary to support anticipated operating needs, cover debt service requirements, meet capital expenditures and discretionary

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

investment needs, fund certain acquisition opportunities that may arise and allow for payment of dividends for the foreseeable future. Borrowings under the Revolving Facility are unsecured and may be used for general corporate purposes. The Company’s ability to borrow or issue securities is dependent upon, among other things, prevailing economic, financial and market conditions. At December 31, 2022, the Company had $1.20 billion of unused borrowing capacity under its Revolving Facility and Trade Receivable Facility.

The Company may be required to obtain additional financing in order to fund certain strategic acquisitions or to refinance outstanding debt. Any strategic acquisition of size would likely require an appropriate balance of newly-issued equity with debt in order to maintain a composite investment-grade credit rating. The Company is exposed to credit markets through the interest cost related to borrowings under its Revolving Facility and Trade Receivable Facility.

Postretirement medical benefits will be paid from the Company’s assets. The obligation, if any, for retiree medical payments is subject to the terms of the plan. At December 31, 2022, the Company’s recorded benefit obligation related to these benefits totaled $8.9 million.

The Company has other retirement benefits related to pension plans. At December 31, 2022, the fair value of the qualified pension plans’ assets exceeded the projected benefit obligation by $295.3 million. The Company estimates that it will make contributions of $25.0 million to qualified pension plans in 2023. Any contributions beyond 2023 are currently undeterminable and will depend on the investment return on the related pension assets. At December 31, 2022, the Company had a total obligation of $85.8 million related to unfunded nonqualified pension plans and expects to make contributions of $11.5 million to these plans in 2023.

At December 31, 2022, the Company had $3.8 million accrued for uncertain tax positions, including interest of $0.2 million. Such liabilities may become payable if the tax positions are not sustained upon examination by a taxing authority.

In connection with normal, ongoing operations, the Company enters into market-rate leases for property, plant and equipment and royalty commitments principally associated with leased land and mineral reserves. Additionally, the Company enters into equipment rentals to meet shorter-term, nonrecurring and intermittent needs. At December 31, 2022, the Company had $388.0 million in operating lease obligations and $199.9 million in finance lease obligations, representing the present value of future payments. The Company also had $8.6 million of lease obligations classified as held for sale. The imputed interest on operating and finance lease obligations was $177.3 million. Management anticipates that, in the ordinary course of business, the Company will enter into additional royalty agreements for land and mineral reserves during 2023. As permitted, short-term leases are excluded from ASC 842 requirements and future noncancelable obligations for these leases as of December 31, 2022 are immaterial.

As of December 31, 2022, future interest payable on the Company’s publicly traded debt through the various maturity dates was $2.13 billion. The Company had obligations related to contracts of affreightment not accounted for as a lease and royalty agreements totaling $97.2 million and $156.3 million, respectively, as of December 31, 2022. The Company had purchase commitments for property, plant and equipment of $130.4 million as of December 31, 2022. In addition, during 2022, the Company entered into a commitment for 691 railcars at an aggregate value of $75.8 million. The Company also had other purchase obligations related to energy and service contracts which totaled $198.1 million as of December 31, 2022.

The Company has entered into standby letter of credit agreements relating to certain insurance claims, contract performance and permit requirements. At December 31, 2022, the Company had contingent liabilities guaranteeing its own performance under these outstanding letters of credit of $21.8 million.

In the normal course of business, at December 31, 2022, the Company was contingently liable for $678.5 million in surety bonds, which guarantee its own performance and are required by certain states and municipalities and their related agencies. The Company has indemnified the underwriting insurance companies against any exposure under the surety bonds. In the Company’s past experience, no material claims have been made against these financial instruments.

The Company is a guarantor with an unconsolidated affiliate for a $15.0 million revolving line of credit agreement with Truist Bank that has a maturity date of March 2024, of which $2.6 million was outstanding as of December 31, 2022. The affiliate has agreed to reimburse and indemnify the Company for any payments and expenses the Company may incur from this agreement.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

The Company holds a lien on the affiliate’s membership interest in a joint venture as collateral for payment under the revolving line of credit.

The Company’s audited consolidated financial statements include certain critical estimates regarding the effect of matters that are inherently uncertain. These estimates require management’s subjective and complex judgments. Amounts reported in the Company’s consolidated financial statements could differ materially if management used different assumptions in making these estimates, resulting in actual results differing from those estimates. Methodologies used and assumptions selected by management in making these estimates, as well as the related disclosures, have been reviewed by and discussed with the Company’s Audit Committee. Management’s determination of the critical nature of accounting estimates and judgments may change from time to time depending on facts and circumstances that management cannot currently predict.

Goodwill is required to be tested annually for impairment. An interim review is performed between annual tests if facts and circumstances indicate a potential impairment. The Company performs its impairment evaluation as of October 1, which represents the annual evaluation date. The impairment review of goodwill is a critical accounting estimate because goodwill represented 24% (excluding goodwill allocated to assets held for sale) of the Company’s total assets at December 31, 2022; the review requires management to apply judgment and make key assumptions; and an impairment charge could be material to the Company’s financial condition and results of operations.

Certain operating segments within the Building Materials business meet the aggregation criteria and are consolidated into reportable segments for financial reporting. The Company’s reporting units, which represent the level at which goodwill is tested for impairment, are based on the operating segments of the Building Materials business. Goodwill is assigned to the respective reporting unit(s) based on the location of acquisitions at the time of consummation. If subsequent organizational changes result in operations being transferred to a different reporting unit, a proportionate amount of goodwill is transferred from the former to the new reporting unit. The Southwest Division is the most significant reporting unit and includes $1.8 billion of the Company’s goodwill. There is also $1.1 billion of goodwill in the West Division reporting unit. There is no goodwill related to the Magnesia Specialties business.

Goodwill is tested for impairment by comparing the reporting unit’s fair value to its carrying value, which represents a Step-1 analysis. However, prior to Step 1, the Company may perform an optional qualitative assessment, or Step 0. As part of the qualitative assessment, the Company considers, among other things, the following events and circumstances: macroeconomic conditions, industry and market conditions, cost factors, overall financial performance and other business or reporting unit-specific events. If the Company concludes it is more-likely-than-not (i.e., a likelihood of more than 50%) that a reporting unit’s fair value is higher than its carrying value, the Company does not perform any further goodwill impairment testing for that reporting unit. Otherwise, it proceeds to Step 1 of its goodwill impairment analysis. If the reporting unit’s fair value exceeds its carrying value, no further calculation is necessary. A reporting unit with a carrying value in excess of its fair value constitutes a Step-1 failure and results in an impairment charge. When the Company validates its conclusion by measuring fair value, it may resume performing a qualitative assessment for a reporting unit in any subsequent period. The Company may bypass the qualitative assessment for any reporting unit in any period and proceed directly with the quantitative calculation in Step 1. The Company performs a Step-1 analysis for all its reporting units every three years.

For the 2022 annual impairment evaluation, the Company performed a Step-1 analysis for all reporting units. The fair values were calculated using a discounted cash flow model. Key assumptions included management’s estimates of changes in average selling price, shipment volumes and production costs as well as assumptions of future profitability, capital requirements, discount rates ranging from 10.0% to 10.25% and a terminal growth rate of 2.5%. The fair value of all reporting units exceeded the carrying value. For sensitivity purposes, a 100-basis-point increase in the discount rate, holding all other assumptions constant, would still result in all units passing the Step-1 analysis.

Future profitability and capital requirements are, by their nature, estimates. Price, cost and volume assumptions were based on various factors, including historical averages and current forecasts, external sources, and market conditions, while also considering any production capacity constraints. Capital requirements included maintenance-level needs and known efficiency- and capacity-increasing investments.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

A discount rate is calculated for each reporting unit that requires a Step-1 analysis and represents its weighted average cost of capital. The calculation of the discount rate includes the following components, which are primarily based on published sources: equity risk premium, historical beta, risk-free interest rate, small-stock premium and borrowing rate.

The terminal growth rate was based on anticipated average GDP increases post-2023.

Management believes that all assumptions used were reasonable based on historical operating results and expected future trends. However, if future operating results are unfavorable as compared with forecasts, the results of future goodwill impairment evaluations could be negatively affected. Further, mineral reserves, which represent underlying assets producing the reporting units’ cash flows for the aggregates product line, are depleting assets by their nature. Any potential impairment charges from future evaluations represent a risk to the Company.

The Company sponsors noncontributory defined benefit pension plans that cover substantially all employees and a Supplemental Excess Retirement Plan (SERP) for certain retirees (see Note K to the consolidated financial statements). Annually, as of December 31, management remeasures the defined benefit pension plans’ projected benefit obligation based on the present value of the projected future benefit payments to all participants for services rendered to date, reflecting expected future pay increases through the participants’ expected retirement dates. A discount rate assumption is selected annually based on corporate bond rates as of the measurement date to calculate the present value of the projected benefit obligation.

Annual pension expense, referred to as net periodic benefit cost within the consolidated financial statements, (inclusive of SERP expense) consists of several components:

The aforementioned components are calculated annually to determine the annual pension expense.

Management believes the selection of assumptions related to the annual pension expense and related projected benefit obligation is a critical accounting estimate due to the high degree of volatility in the expense and obligation dependent on selected assumptions. The key assumptions are as follows:

Management’s selection of the discount rate is based on an analysis that estimates the current rate of return for high-quality, fixed-income investments with maturities matching the payment of pension benefits that could be purchased to settle the

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

obligations. The Company selected a hypothetical portfolio of Moody’s Aa bonds, with maturities that match the benefit obligations, to determine the discount rate. At December 31, 2022, the Company selected a discount rate assumption of 5.88%, a 265-basis-point increase compared with the December 31, 2021 assumption. Of the four key assumptions, the discount rate is generally the most volatile and sensitive estimate. Accordingly, a change in this assumption has the most significant impact on the annual pension expense and the projected benefit obligation.

Management’s selection of the rate of increase in future compensation levels, which reflects cost of living adjustments and merit and promotion increases, is generally based on the Company’s historical increases in pensionable earnings, while giving consideration to any future expectations. A higher rate of increase results in higher pension expense and a higher projected benefit obligation. The assumed long-term rate of increase is 4.50%.

Management’s selection of the expected long-term rate of return on pension fund assets is based on a building-block approach, whereby the components are weighted based on the allocation of pension plan assets. Based on the currently projected returns on these assets and related expenses, the Company selected an expected return on assets of 6.75%, the same as the prior-year rate. The following table presents the expected return on pension assets as compared with the actual return on pension assets:

The difference between the expected return and the actual return on pension assets is included in actuarial gains and losses, which are amortized into annual pension expense as previously described.

At December 31, 2022 and 2021, the Company estimated the remaining lives of participants in the pension plans using the Society of Actuaries’ Pri-2012 Base Mortality Table. The no-collar table was used for salaried participants and the blue-collar table was used for hourly participants, both adjusted to reflect the historical experience of the Company’s participants. The Company selected the MP-2020 scale for mortality improvement at December 31, 2022 and 2021.

Assumptions are selected on December 31 to calculate the succeeding year’s expense. The assumptions selected at December 31, 2022 were as follows:

Using these assumptions, pension benefit obligation as of December 31, 2022 was $857.6 million and 2023 pension expense is expected to be approximately $16.6 million based on current demographics and structure of the plans. Changes in the underlying assumptions would have the following estimated impact on the obligation and expected expense:

The Company made pension plan and SERP contributions of $90.2 million in 2022 and $482.6 million during the five-year period ended December 31, 2022. In total, the Company’s pension plans are overfunded (fair value of plan assets exceeds the projected benefit obligation) by $209.5 million at December 31, 2022. The Company’s projected benefit obligation was $857.6 million at December 31, 2022, a decrease of $277.8 million, or 24%, versus the prior year. This decrease was driven by an increased actuarial gain primarily attributable to a higher discount rate compared with the prior year. The Company expects to make pension plan and SERP contributions of $36.5 million in 2023, of which $25.0 million is voluntary.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

The Company uses the liability method to determine its provision for income taxes. Accordingly, the annual provision for income taxes reflects estimates of the current liability for income taxes, estimates of the tax effect of financial reporting versus tax basis differences using statutory income tax rates and management’s judgment with respect to any valuation allowances on deferred tax assets and accruals for uncertain tax positions. The result is management’s estimate of the annual effective tax rate (the ETR).

Income for tax purposes is determined through the application of the rules and regulations under the United States Internal Revenue Code and the statutes of various foreign, state and local tax jurisdictions in which the Company conducts business. Changes in the statutory tax rates and/or tax laws in these jurisdictions can have a material impact on the ETR. The effect of these changes, if material, is recognized when the change is enacted.

As prescribed by these tax regulations, as well as generally accepted accounting principles, the manner in which revenues and expenses are recognized for financial reporting and income tax purposes is not always the same. Therefore, these differences between the Company’s pretax income for financial reporting purposes and the amount of taxable income for income tax purposes are treated as either temporary or permanent, depending on their nature.

Temporary differences reflect revenues or expenses that are recognized in financial reporting in one period and taxable income in a different period. An example of a temporary difference is the use of the straight-line method of depreciation of machinery and equipment for financial reporting purposes and the use of an accelerated method for income tax purposes. Temporary differences result from differences between the financial reporting basis and tax basis of assets or liabilities and give rise to deferred tax assets or liabilities (i.e., future tax deductions or future taxable income). Therefore, when temporary differences occur, they are offset by a corresponding change in a deferred tax account. As such, total income tax expense as reported in the Company’s consolidated statements of earnings is not changed by temporary differences.

The Company has deferred tax liabilities, primarily for right-of-use assets, property, plant and equipment, goodwill and other intangibles, employee pension and postretirement benefits and partnerships and joint ventures. The deferred tax liabilities attributable to property, plant and equipment relate to accelerated depreciation and depletion methods used for income tax purposes as compared with the straight-line and units-of-production methods used for financial reporting purposes. These temporary differences will reverse over the remaining useful lives of the related assets. The deferred tax liabilities attributable to goodwill arise as a result of amortizing goodwill for income tax purposes but not for financial reporting purposes. This temporary difference reverses when goodwill is written off for financial reporting purposes, either through divestitures or an impairment charge. The timing of such events cannot be estimated. The deferred tax liabilities attributable to employee pension and postretirement benefits relate to deductions as plans are funded for income tax purposes compared with deductions for financial reporting purposes based on accounting standards. The reversal of these differences depends on the timing of the Company’s contributions to the related benefit plans as compared to the annual expense for financial reporting purposes. The deferred tax liabilities attributable to partnerships and joint ventures relate to the difference between the tax basis of the investments in partnerships and joint ventures when compared to the basis for financial reporting purposes. The temporary difference reverses through differences recognized over the life of the investment or through divestiture.

The Company has deferred tax assets, primarily for inventories, unrecognized losses related to the funded status of the pension and postretirement benefit plans, lease liabilities, valuation reserves, net operating loss carryforwards and tax credit carryforwards. The deferred tax assets attributable to inventories and valuation reserves relate to the deduction of estimated cost reserves and various period expenses for financial reporting purposes that are deductible in a later period for income tax purposes. The reversal of these differences depends on facts and circumstances, including the timing of deduction for income tax purposes for reserves previously established and the establishment of additional reserves for financial reporting purposes. The deferred tax assets attributable to unvested stock-based compensation awards relate to differences in the timing of deductibility for financial reporting purposes versus income tax purposes. For financial reporting purposes, the fair value of the awards is deducted ratably over the requisite service period. For income tax purposes, no deduction is allowed until the award is vested or no longer subject to substantial risk of forfeiture. The Company reflects all excess tax benefits and tax deficiencies in income tax expense as a discrete event in the period in which the award vests or settles, increasing volatility in the income tax rate from period to period.

The Company’s Board of Directors and management regularly review strategic long-term plans, including potential investments in value-added acquisitions of related or similar businesses, which would increase the Company’s market presence and/or are

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

related to the Company’s existing markets. When an acquisition is completed, the Company’s consolidated statements of earnings include the operating results of the acquired business starting from the date of acquisition, which is the date control is obtained. The purchase price is determined based on the fair value of assets and equity interests given to the seller and any future obligations to the seller as of the date of acquisition. The Company allocates the purchase price to the fair values of the tangible and intangible assets acquired and liabilities assumed as valued at the date of acquisition. Goodwill is recorded for the excess of the purchase price over the net of the fair value of the identifiable assets acquired and liabilities assumed as of the acquisition date. The purchase price allocation is a critical accounting policy because the estimation of fair values of acquired assets and assumed liabilities is judgmental and requires various assumptions. Further, the amounts and useful lives assigned to depreciable and amortizable assets versus amounts assigned to goodwill and indefinite-lived intangible assets, which are not amortized, can significantly affect the results of operations in the period of and for periods subsequent to a business combination.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction, and, therefore, represents an exit price. Fair value measurement assumes the highest and best use of the asset by market participants, considering the use of the asset that is physically possible, legally permissible, and financially feasible at the measurement date. The Company assigns the highest level of fair value available to assets acquired and liabilities assumed based on the following options:

Level 1 fair values are used to value investments in publicly traded entities and assumed obligations for publicly traded long-term debt.

Level 2 fair values are typically used to value acquired receivables, inventories, machinery and equipment, land, buildings, deferred income tax assets and liabilities, and accruals for payables, asset retirement obligations, environmental remediation and compliance obligations, and contingencies. Additionally, Level 2 fair values are typically used to value assumed contracts at other-than-market rates.

Level 3 fair values are used to value acquired mineral reserves and mineral interests produced and sold as final products, and separately-identifiable intangible assets. The fair values of mineral reserves and mineral interests are determined using an excess earnings approach, which requires significant judgment to estimate future cash flows, net of capital investments in the specific operation and contributory asset charges. The estimate of future cash flows is based on available historical information and future expectations and assumptions determined by management, but is inherently uncertain. Significant assumptions used to estimate future cash flows include changes in forecasted revenues based on sales price and shipment volumes as well as forecasted expenses inclusive of production costs and capital needs. The present value of the projected net cash flows represents the fair value assigned to mineral reserves and mineral interests. The discount rate is a significant assumption used in the valuation model and is based on the required rate of return that a hypothetical market participant would require if purchasing the acquired business, with an adjustment for the risk of these assets not generating the projected cash flows.

The Company values separately-identifiable acquired intangible assets which may include, but are not limited to, permits, customer relationships, water rights and noncompetition agreements. The fair values of these assets are typically determined by an excess earnings method, a replacement cost method or, in the case of water rights, a market approach.

The useful lives of amortizable intangible assets and the remaining useful lives for acquired machinery and equipment have a significant impact on earnings. The selected lives are based on the expected periods that the assets will provide value to the Company subsequent to the business combination.

The Company may adjust the amounts recognized for a business combination during a measurement period after the acquisition date. Any such adjustments are based on the Company obtaining additional information that existed at the acquisition date regarding the assets acquired or the liabilities assumed. Measurement-period adjustments are generally recorded as increases or decreases to the goodwill recognized in the transaction. The measurement period ends once the Company has obtained all necessary information that existed as of the acquisition date, but does not extend beyond one year from the date of acquisition. Any adjustments to assets acquired or liabilities assumed beyond the measurement period are recorded through earnings.

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

Net property, plant and equipment (excluding the amount allocated to assets held for sale) represented 42% of total assets at December 31, 2022. Accordingly, accounting for these assets represents a critical accounting policy. Useful lives of the assets can vary depending on factors, including production levels, geographic location, portability and maintenance practices. Additionally, climate and inclement weather can reduce the useful life of an asset. Historically, the Company has not recognized significant losses on the disposal or retirement of fixed assets.

Aggregates mineral reserves and mineral interests are components within the plant, property and equipment balance on the consolidated balance sheets. The Company evaluates aggregates reserves, including those used in the cement manufacturing process, in several ways, depending on the geology at a particular location and whether the location is a greensite, an acquisition or an existing operation. Greensites require an extensive drilling program before any significant investment is made in terms of time, site development or efforts to obtain appropriate zoning and permitting (see Environmental Regulation and Litigation section). The depth of overburden and the quality and quantity of the aggregates reserves are significant factors in determining whether to pursue opening the site. Further, the estimated average selling price for products in a market is also a significant factor in concluding that reserves are economically mineable. If the Company’s analysis based on these factors is satisfactory, the total aggregates reserves available are calculated and a determination is made whether to open the location. Reserve evaluation at existing locations is typically performed to evaluate purchasing adjoining properties, for quality control, calculating overburden volumes and for mine planning. Reserve evaluation of acquisitions may require a higher degree of sampling to locate any problem areas that may exist and to verify the total reserves.

Well-ordered subsurface sampling of the underlying deposit is basic to determining reserves at any location. This subsurface sampling usually involves one or more types of drilling, determined by the nature of the material to be sampled and the particular objective of the sampling. The Company’s objectives are to ensure that the underlying deposit meets aggregates specifications and the total reserves on site are sufficient for mining and economically recoverable. Locations underlain with hard rock deposits, such as granite and limestone, are drilled using the diamond core method, which provides the most useful and accurate samples of the deposit. Selected core samples are tested for soundness, abrasion resistance and other physical properties relevant to the aggregates industry and depend on the aggregates use. The number and depth of the holes are determined by the size of the site and the complexity of the site-specific geology. Some geological factors that may affect the number and depth of holes include faults, folds, chemical irregularities, clay pockets, thickness of formations and weathering. A typical spacing of core holes on the area to be tested is one hole for every four acres, but wider spacing may be justified if the deposit is homogeneous.

Despite previous drilling and sampling, once accessed, the quality of reserves within a deposit can vary. Construction contracts, for the infrastructure market in particular, include specifications related to the aggregates material. If a flaw in the deposit is discovered, the aggregates material may not meet the required specifications. Although it is possible that the aggregates material can still be used for non-specification uses, this can have an adverse effect on the Company’s ability to serve certain customers or on the Company’s profitability. In addition, other issues can arise that limit the Company’s ability to access reserves in a particular quarry, including geological occurrences, blasting practices and zoning issues.

Locations underlain with sand and gravel are typically drilled using the auger method, whereby a six-inch corkscrew brings up material from below the ground which is then sampled. Deposits in these locations are typically limited in thickness. Additionally, the quality and sand-to-gravel ratio of the deposit can vary both horizontally and vertically. Hole spacing at these locations is approximately one hole for every acre to ensure a representative sampling.

The geologist conducting the reserve evaluation makes the decision as to the number of holes and the spacing in accordance with standards and procedures established by the Company. Further, the anticipated heterogeneity of the deposit, based on U.S. geological maps, also dictates the number of holes drilled.

The generally accepted reserve categories for the aggregates industry and the designations the Company uses for reserve categories are summarized as follows:

Proven Reserves – These reserves are designated using closely spaced drill data as described above and a determination by a professional geologist that the deposit is relatively homogeneous based on the drilling results and exploration data provided in U.S. geologic maps, the U.S. Department of Agriculture soil maps, aerial photographs and/or electromagnetic, seismic or other surveys conducted by independent geotechnical engineering firms. The proven reserves that are recorded reflect reductions incurred through quarrying that result from leaving ramps, safety benches, pillars (underground) and the fines (small particles) that will be generated during processing. Proven reserves

Part II ♦ Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations

are further reduced by reserves that are under the plant and stockpile areas, as well as setbacks from neighboring property lines. The Company typically assumes a loss factor of 25%. However, the assumed loss factor at coastal operations is approximately 40% due to the nature of the material. The assumed loss factor for underground operations is 35% primarily due to pillars.

Probable Reserves – These reserves are inferred utilizing fewer drill holes and/or assumptions about the economically recoverable reserves based on local geology or drill results from adjacent properties.

The Company’s proven and probable reserves reflect reasonable economic and operating constraints as to maximum depth of overburden and stone excavation, and also include reserves at the Company’s inactive and undeveloped sites, including some sites where permitting and zoning applications will not be filed until warranted by expected future growth. The Company has historically been successful in obtaining and maintaining appropriate zoning and permitting (see Environmental Regulation and Litigation section).

Mineral reserves and mineral interests, when acquired in connection with a business combination, are valued using an excess earnings approach for the life of the proven and probable reserves.

The Company uses proven and probable reserves as the denominator in its units-of-production calculation to record depletion expense for its mineral reserves and mineral interests. For 2022, depletion expense was $59.8 million.

The Company begins capitalizing quarry development costs at a point when reserves are determined to be proven or probable, economically mineable and when demand supports investment in the market. Capitalization of these costs ceases when production commences. Capitalized quarry development costs are classified as land improvements.

New mining areas may be developed at existing quarries in order to access additional reserves. When this occurs, management reviews the facts and circumstances of each situation in making a determination as to the appropriateness of capitalizing or expensing the related pre-production development costs. If the additional mining location operates in a separate and distinct area of a quarry, the costs are capitalized as quarry development costs and depreciated over the life of the uncovered reserves. Further, a separate asset retirement obligation is created for additional mining areas when the liability is incurred. Once a new mining area enters the production phase, all post-production stripping costs are expensed as incurred as periodic inventory production costs.

Further, increased highway construction funding pressures resulting from either federal or state issues can affect profitability. If these negatively affect transportation budgets more than in the past, construction spending could be reduced. Cement is subject to cyclical supply and demand and price fluctuations.

The Company’s principal business serves customers in construction markets. This concentration could increase the risk of potential losses on customer receivables; however, payment bonds normally posted on public projects, together with lien rights on private projects, mitigate the risk of uncollectible receivables. The level of demand in the Company’s end-use markets, production levels and the management of production costs will affect the operating leverage of the Building Materials business and, therefore, profitability. Production costs in the Building Materials business are also sensitive to energy and raw material prices, both directly and indirectly. Diesel fuel, coal and other consumables change production costs directly through consumption or indirectly by increased energy-related input costs, such as steel, explosives, tires and conveyor belts. Fluctuating diesel fuel pricing also affects transportation costs, primarily through fuel surcharges in the Company’s long-haul distribution network. The Magnesia Specialties business is sensitive to changes in domestic steel capacity utilization as well as the absolute price and fluctuation in the cost of natural gas.

Transportation in the Company’s long-haul network, particularly the supply of railcars and locomotive power and condition of rail infrastructure to move trains, affects the Company’s efficient transportation of aggregates products in certain markets, most notably Texas, Colorado, Florida, North Carolina and the Gulf Coast. In addition, availability of railcars and locomotives affects the Company’s movement of essential dolomitic lime for magnesia chemicals to both the Company’s plant in Manistee, Michigan, and its customers. The availability of trucks, drivers and railcars to transport the Company’s product, particularly in markets experiencing high growth and increased demand, is also a risk and pressures the associated costs.

All of the Company’s businesses are also subject to weather-related risks that can significantly affect production schedules and profitability. The first and fourth quarters are most adversely affected by winter weather. Hurricane and cyclone activity in the Atlantic Ocean, Pacific Ocean and Gulf Coast generally is most active during the second, third and fourth quarters.

Risks also include shipment declines resulting from economic events beyond the Company’s control.

You should consider these forward-looking statements in light of risk factors discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 and other filings made with the SEC. All of the Company’s forward-looking statements should be considered in light of these factors. In addition, other risks and uncertainties not presently known to the Company or that the Company considers immaterial could affect the accuracy of its forward-looking statements, or adversely affect or be material to the Company. All forward-looking statements are made as of the date of filing or publication and we assume no obligation to update any such forward-looking statements.

Part II ♦ Item 7A – Quantitative and Qualitative Disclosures About Market Risk

As discussed earlier, the Company’s operations are highly dependent upon the interest rate-sensitive construction and steelmaking industries. Consequently, these marketplaces could experience lower levels of economic activity in an environment of rising interest rates or escalating costs (see Business Environment section included under Item 7 – MD&A of this Form 10-K).

Management has considered the current economic environment and its potential impact to the Company’s business. Demand for aggregates products, particularly in the infrastructure construction market, is affected by federal, state and local budget and deficit issues. Further, delays or cancellations of capital projects in the nonresidential and residential construction markets could occur if companies and consumers are unable to obtain affordable financing for construction projects or if consumer confidence is eroded by economic uncertainty.

Demand in the residential and nonresidential construction markets, which combined accounted for 60% of the Company's 2022 aggregates shipments, is affected by interest rates. During 2022, the Federal Reserve raised the target federal funds rate 425 basis points.

Aside from these inherent risks from within its operations, the Company’s earnings are also affected by changes in short-term interest rates and changes in enacted tax laws.

At December 31, 2022, the Company had an $800.0 million Revolving Facility and a $400.0 million Trade Receivable Facility. Borrowings under these facilities bear interest at a variable interest rate. As of December 31, 2022, the Company did not have any outstanding variable-rate debt. However, any future borrowings under the credit facilities or outstanding variable-rate debt are exposed to interest rate risk.

The Company’s results of operations are affected by its pension expense. Assumptions that affect pension expense include the discount rate and, for the qualified defined benefit pension plan only, the expected long-term rate of return on assets. Therefore, the Company has interest rate risk associated with these factors. The impact of hypothetical changes in these assumptions on the Company’s annual pension expense and accrued pension obligation is discussed in the Critical Accounting Policies and Estimates – Pension Expense – Selection of Assumptions section included under Item 7 – MD&A of this Form 10-K.

Any changes in enacted tax laws, rules or regulatory or judicial interpretation, or any change in the pronouncements relating to accounting for income taxes, could materially impact the Company's effective tax rate, tax payments, financial condition and results of operations.

Energy costs, including diesel fuel, natural gas, electricity, coal, petroleum coke and liquid asphalt, represent significant production costs of the Company. The Company may be unable to pass along increases in the costs of energy to customers in the form of price increases for the Company’s products. The cement product line and Magnesia Specialties business each have varying fixed-price agreements for a portion of their future energy requirements. A hypothetical 10% change in the Company’s energy prices in 2023 as compared with 2022, assuming constant volumes, would change 2023 energy expense by $50.0 million.

Cement is a commodity and competition is based principally on price, which is highly sensitive to changes in supply and demand. Prices are often subject to material changes in response to relatively minor fluctuations in supply and demand, general economic conditions and other market conditions beyond the Company’s control. Increases in the production capacity of industry participants or increases in cement imports tend to create an oversupply of such products leading to an imbalance between supply and demand, which can have a negative impact on product prices. There can be no assurance that product prices will not decline in the future or that such declines will not have a material adverse effect on the Company’s business, financial condition and results of operations. A hypothetical 10% change in sales price of the cement product line would impact cement product line revenues by $60.2 million.

Part II ♦ Item 7A – Quantitative and Qualitative Disclosures About Market Risk

Cement is a key raw material in the production of ready mixed concrete. The Company may be unable to pass along increases in the costs of cement and raw materials to customers in the form of price increases for the Company’s products. A hypothetical 10% change in cement costs in 2023 compared with 2022, assuming constant volumes, would change the ready mixed concrete product line cost of sales by $26.2 million. While increases in cement pricing may negatively impact the profitability of the ready mixed concrete operations, the cement business would benefit, although the positive impact may not reflect a direct correlation to the impact to the ready mixed concrete business.

Statement of Responsibility and Management’s Report on Internal Control over Financial Reporting

The management of Martin Marietta Materials, Inc. (the Company or Martin Marietta) is responsible for the consolidated financial statements, the related financial information contained in this Form 10-K and the establishment and maintenance of adequate internal control over financial reporting. The consolidated balance sheets for Martin Marietta, at December 31, 2022 and 2021, and the related consolidated statements of earnings, comprehensive earnings, total equity and cash flows for each of the three years in the period ended December 31, 2022, include amounts based on estimates and judgments and have been prepared in accordance with accounting principles generally accepted in the United States applied on a consistent basis.

A system of internal control over financial reporting is designed to provide reasonable assurance, in a cost-effective manner, that assets are safeguarded, transactions are executed and recorded in accordance with management’s authorization, accountability for assets is maintained and financial statements are prepared and presented fairly in accordance with accounting principles generally accepted in the United States. Internal control systems over financial reporting have inherent limitations and may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The Company operates in an environment that establishes an appropriate system of internal control over financial reporting and ensures that the system is maintained, assessed and monitored on a periodic basis. This internal control system includes examinations by internal audit staff and oversight by the Audit Committee of the Board of Directors.

The Company’s management recognizes its responsibility to foster a strong ethical climate. Management has issued written policy statements that document the Company’s business code of ethics. The importance of ethical behavior is regularly communicated to all employees through the distribution of the Code of Ethical Business Conduct and through ongoing education and review programs designed to create a strong commitment to ethical business practices.

The Audit Committee of the Board of Directors, which consists of four independent, nonemployee directors, meets periodically and separately with management, the independent auditors and the internal auditors to review the activities of each. The Audit

Committee meets standards established by the Securities and Exchange Commission (SEC) and the New York Stock Exchange as they relate to the composition and practices of audit committees.

The management of Martin Marietta is responsible for establishing and maintaining adequate internal control over financial reporting. Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2022. In making this assessment, management used the criteria set forth in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on management’s assessment under the 2013 framework, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2022.

The consolidated financial statements of the Company as of December 31, 2022 and 2021, and for each of the three years in the period ended December 31, 2022, and the effectiveness of the Company’s internal control over financial reporting as of December 31, 2022, have been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report appears on the following pages.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Martin Marietta Materials, Inc. and its subsidiaries (the Company) as of December 31, 2022 and 2021, and the related consolidated statements of earnings, of comprehensive earnings, of total equity and of cash flows for each of the three years in the period ended December 31, 2022, including the related notes and schedule of valuation and qualifying accounts for each of the three years in the period ended December 31, 2022 appearing under Item 15(c) (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

As described in Notes A and D to the consolidated financial statements, the Company’s consolidated goodwill balance was $3.6 billion as of December 31, 2022. The goodwill balance associated with the West Division reporting unit was $1.1 billion. The carrying values of goodwill are reviewed for impairment annually, as of October 1. An interim review is performed between annual tests if facts and circumstances indicate potential impairment. As disclosed by management, the goodwill impairment assessment requires management to apply judgment and make key assumptions. The fair value of the West Division reporting unit was calculated using a discounted cash flow model. Key assumptions included management’s estimates of changes in average selling price, shipment volumes and production costs, as well as assumptions of future profitability, capital requirements, discount rate and terminal growth rate.

The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment of the West Division reporting unit is a critical audit matter are (i) the significant judgment by management when developing the fair value estimate of the West Division reporting unit; (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating management’s significant assumptions related to the discount rate and changes in average selling price, shipment volumes and production costs, and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s goodwill impairment assessment, including controls over the valuation of the West Division reporting unit. These procedures also included, among others (i) testing management’s process for developing the fair value estimate, (ii) evaluating the appropriateness of the discounted cash flow model, (iii) testing the completeness and accuracy of underlying data used in the model, and (iv) evaluating the reasonableness of the significant assumptions used by management related to the discount rate and changes in average selling price, shipment volumes and production costs. Evaluating management’s assumptions related to changes in average selling price, shipment volumes and production costs involved evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of the reporting unit, (ii) the consistency with external industry data, and (iii) whether the assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in evaluating the reasonableness of the discount rate assumption.

The accompanying Notes to the Financial Statements are an integral part of these statements.

Note A: Accounting Policies

Organization. Martin Marietta is a natural resource-based building materials company. The Company supplies aggregates (crushed stone, sand and gravel) through its network of approximately 350 quarries, mines and distribution yards in 28 states, Canada and The Bahamas. Martin Marietta also provides cement and downstream products and services, namely, ready mixed concrete, asphalt and paving, in vertically-integrated structured markets where the Company also has a leading aggregates position. Specifically, the Company has two cement plants and several cement distribution facilities in Texas; ready mixed concrete plants in Arizona and Texas; and asphalt plants in Arizona, California, Colorado and Minnesota. Paving services are located in California and Colorado. In addition, the Company also has one cement plant, related cement distribution terminals and ready mixed concrete operations in California that are classified as assets held for sale and reported as discontinued operations as of and for the years ended December 31, 2022 and 2021. The Company’s heavy-side building materials are used in infrastructure, nonresidential and residential construction projects. Aggregates are also used in agricultural, utility and environmental applications and as railroad ballast. The aggregates, cement, ready mixed concrete and asphalt and paving product lines are reported collectively as the Building Materials business.

As of December 31, 2022, the Building Materials business contains the following reportable segments: East Group and West Group. The East Group consists of the East and Central divisions and operates in Alabama, Florida, Georgia, Indiana, Iowa, Kansas, Kentucky, Maryland, Minnesota, Missouri, Nebraska, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia, West Virginia, Nova Scotia and The Bahamas. The West Group is comprised of the Southwest and West divisions and operates in Arizona, Arkansas, California, Colorado, Louisiana, Oklahoma, Texas, Utah, Washington and Wyoming. The following states accounted for 64% of the Building Materials business’ 2022 total revenues: Texas, Colorado, North Carolina, Minnesota and California.

The Company also operates a Magnesia Specialties business, which produces magnesia-based chemical products used in industrial, agricultural and environmental applications, and dolomitic lime sold primarily to customers for steel production and soil stabilization. Magnesia Specialties’ production facilities are located in Ohio and Michigan, and products are shipped to customers domestically and worldwide.

Basis of Presentation and Use of Estimates. The Company’s consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States, which require management to make certain estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenues and expenses. Such estimates include the valuation of investments, accounts receivable, inventories, goodwill, other intangible assets and other long-lived assets, as well as assumptions used in the calculation of income tax expense, retirement and postemployment benefits, stock-based compensation, the allocation of the purchase price to the fair values of assets acquired and liabilities assumed as part of business combinations and revenue recognition for service contracts. These estimates and assumptions are based on management’s judgment. Management evaluates estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and adjusts such estimates and assumptions when facts and circumstances dictate. Changes in credit, equity and energy markets and changes in construction activity increase the uncertainty inherent in certain estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from estimates. Changes in estimates, including those resulting from changes in the economic environment, are reflected in the consolidated financial statements for the period in which the change in estimate occurs.

Basis of Consolidation. The consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. Partially-owned affiliates are either consolidated or accounted for using the cost method or the equity method, depending on the level of ownership interest or the Company’s ability to exercise control over the affiliates’ operations. Intercompany balances and transactions between subsidiaries have been eliminated in consolidation.

Revenue Recognition. Total revenues include sales of products and services provided to customers, net of discounts or allowances, if any, and include freight and delivery costs billed to customers. Product revenues are recognized when control of the promised good is transferred to unaffiliated customers, typically when finished products are shipped. Intersegment and interproduct revenues are eliminated in consolidation. Service revenues are derived from the paving business and are recognized using the percentage-of-completion method under the cost-to-cost approach. Under the cost-to-cost approach, recognized contract revenue is determined by multiplying the total estimated contract revenue by the estimated percentage of completion. Contract costs are recognized as incurred. The percentage of completion is determined on a contract-by-contract basis using project costs


Form 10-K ♦ Page 79

Part II ♦ Item 8 – Financial Statements and Supplementary Data

incurred to date as a percentage of total estimated project costs. The Company believes the cost-to-cost approach is appropriate, as the use of asphalt in a paving contract is relatively consistent with the performance of the related paving services. Paving contracts, notably with governmental entities, may contain performance bonuses based on quality specifications. Given the uncertainty of meeting the criteria until the performance obligation is completed, performance bonuses are recognized as revenues when and if achieved. Performance bonuses were not material to the Company’s consolidated results of operations for the years ended December 31, 2022, 2021 and 2020. When the Company arranges third-party freight to deliver products to customers, the Company has elected the delivery to be a fulfillment activity rather than a separate performance obligation. Further, the Company acts as a principal in the delivery arrangements and, as required by Accounting Standards Codification (ASC) 606, the related revenues and costs are presented gross in the consolidated statements of earnings and are recognized consistently with the timing of the product revenues.

Freight and Delivery Costs. Freight and delivery costs represent pass-through transportation costs incurred and paid by the Company to third-party carriers to deliver products to customers. These costs are then billed to the customers.

Cash, Cash Equivalents and Restricted Cash. Cash equivalents are comprised of highly-liquid instruments with original maturities of three months or less from the date of purchase.

As of December 31, 2022 and 2021, the Company had $0.8 million and $0.5 million, respectively, of restricted cash, which was invested in an account designated for the purchase of like-kind exchange replacement assets under Section 1031 of the Internal Revenue Code. The Company is restricted from utilizing the cash for purposes other than the purchase of qualified assets for 180 days from receipt of the proceeds from the sale of the exchanged property. Any unused cash at the end of the 180 days is transferred to unrestricted accounts of the Company and used for general corporate purposes.

The statements of cash flows reflect cash flow changes and balances for cash, cash equivalents and restricted cash on an aggregated basis. The following table reconciles cash, cash equivalents and restricted cash as reported on the consolidated balance sheets to the aggregated amounts presented on the consolidated statements of cash flows:


December 31 (in millions)	2022		2021		2020
Cash and cash equivalents	$	358.0	$	258.4	$	207.3
Restricted cash		0.8		0.5		97.1
Total cash, cash equivalents and restricted cash presented in the consolidated statements of cash flows	$	358.8	$	258.9	$	304.4

Restricted Investments. At December 31, 2022, the Company had $704.6 million of restricted investments, representing assets irrevocably transferred to an escrow trust account during 2022 to satisfy and discharge the Company's $700 million of 0.650% Senior Notes due 2023 (the 0.650% Senior Notes) (see Note H). The assets in the escrow trust account may not be used for any purpose other than to satisfy the remaining interest payments and to repay the principal amount of the 0.650% Senior Notes on the maturity date of July 15, 2023. The assets transferred to the escrow trust account are invested in a U.S. Treasury securities fund (see Note I) and investment returns on those trust assets are for the account of the Company (after satisfaction of all amounts payable in connection with the 0.650% Senior Notes). The Company consolidated the trust account on its consolidated balance sheet at December 31, 2022.

Accounts Receivable. Accounts receivable are stated at cost. The Company does not typically charge interest on customer accounts receivable. The Company records an allowance for credit losses, which includes a provision for probable losses based on historical write-offs, adjusted for current conditions as deemed necessary, and a specific reserve for accounts deemed at risk. The allowance is the Company’s estimate for receivables as of the balance sheet date that ultimately will not be collected. Any changes in the allowance are reflected in earnings in the period in which the change occurs. The Company writes-off accounts receivable when it becomes probable, based upon customer facts and circumstances, that such amounts will not be collected.

Inventories Valuation. Finished products and in-process inventories are stated at the lower of cost or net realizable value using standard costs, which approximate the first-in, first-out method. Carrying value for parts and supplies are determined by the weighted-average cost method. The Company records an allowance for finished product inventories based on an analysis of future demand and inventory on hand in excess of historical sales for a twelve-month period or an annual average for a period of up to five years. The Company also establishes an allowance for parts over five years old and supplies over a year old.

Post-production stripping costs, which represent costs of removing overburden and waste materials to access mineral deposits, are a component of inventory production costs and recognized as incurred.


Form 10-K ♦ Page 80

Part II ♦ Item 8 – Financial Statements and Supplementary Data

Property, Plant and Equipment. Property, plant and equipment are stated at cost.

The estimated service lives for property, plant and equipment are as follows:


Class of Assets		Range of Service Lives
Buildings		5 to 30 years
Machinery & Equipment		2 to 20 years
Land Improvements		5 to 60 years

The Company reviews relevant facts and circumstances to determine whether to capitalize or expense pre-production stripping costs when additional pits are developed at an existing quarry. If the additional pit operates in a separate and distinct area of the quarry, these costs are capitalized as quarry development costs and depreciated over the life of the uncovered reserves. Additionally, a separate asset retirement obligation is created for additional pits when the liability is incurred. Once a pit enters the production phase, all post-production stripping costs are charged to inventory production costs as incurred.

Mineral reserves and mineral interests acquired in connection with a business combination are valued using an income approach for the estimated life of the reserves. The Company’s aggregates reserves average approximately 75 years based on the 2022 annual production level.

Depreciation is computed based on estimated service lives using the straight-line method. Depletion of mineral reserves is calculated based on proven and probable reserves using the units-of-production method on a quarry-by-quarry basis.

Property, plant and equipment are reviewed for impairment whenever facts and circumstances indicate that the carrying amount of an asset group may not be recoverable. An impairment loss is recognized if expected future undiscounted cash flows over the estimated remaining service life of the related asset group are less than the asset group’s carrying value.

Repair and Maintenance Costs. Repair and maintenance costs that do not substantially extend the life of the Company’s plant and equipment are expensed as incurred.

Leases. If the Company determines a contract is or contains a lease at the inception of an agreement, the Company records a right-of-use (ROU) asset, which represents the Company’s right to use an underlying leased asset, and a lease liability, which represents the Company’s obligation to make lease payments. The ROU asset and lease liability are recorded on the consolidated balance sheets at the present value of the future lease payments over the lease term at commencement date. The Company determines the present value of lease payments based on the implicit interest rate, which may be explicitly stated in the lease, if available, or may be the Company’s estimated collateralized incremental borrowing rate based on the term of the lease. Initial ROU assets also include any lease payments made at or before commencement date and any initial direct costs incurred and are reduced by lease incentives. Certain of the Company’s leases contain renewal and/or termination options. The Company recognizes renewal or termination options as part of its ROU assets and lease liabilities when the Company has the unilateral right to renew or terminate and it is reasonably certain these options will be exercised.

Some leases require the Company to pay non-lease components, which may include taxes, maintenance, insurance and certain other expenses applicable to the leased property, and are primarily variable costs. The Company accounts for lease and non-lease components as a single amount, with the exception of railcar and fleet vehicle leases, for which the Company separately accounts for the lease and non-lease components.

Leases are evaluated and determined to be either finance leases or operating leases. The lease is a finance lease if it transfers ownership to the underlying asset by the end of the lease term; includes a purchase option that is reasonably certain to be exercised; has a lease term for the major part of the remaining economic life of the underlying asset; has a present value of the sum of the lease payments (including renewal options) that equals or exceeds substantially all of the fair value of the underlying asset; or is for an underlying asset that is of a specialized nature and is expected to have no alternative use to the lessor at the end of the lease term. If none of these terms exist, the lease is an operating lease.

Leases with an initial lease term of one year or less are not recorded on the consolidated balance sheets. Costs for these leases are expensed as incurred.


Form 10-K ♦ Page 81

Part II ♦ Item 8 – Financial Statements and Supplementary Data

In the consolidated statements of earnings, operating lease expense, which is recognized on a straight-line basis over the lease term, and the amortization of finance lease ROU assets are included in the Cost of revenues - products and services or Selling, general and administrative expenses line items in the consolidated statements of earnings. Accretion on the liabilities for finance leases is included in interest expense.

Goodwill and Other Intangible Assets. Goodwill represents the excess purchase price paid for acquired businesses over the estimated fair value of identifiable assets and liabilities. Other intangible assets represent amounts assigned principally to contractual agreements and are either amortized ratably over the useful lives to the Company or not amortized if deemed to have an indefinite useful life.

The Company’s reporting units, which represent the level at which goodwill is tested for impairment, are based on the operating segments of the Building Materials business. Goodwill is assigned to the respective reporting unit(s) based on the location of acquisitions at the time of consummation. Goodwill is tested for impairment by comparing each reporting unit’s fair value to its carrying value, which represents a Step-1 approach. However, prior to Step 1, the Company may perform a qualitative assessment and evaluate macroeconomic conditions, industry and market conditions, cost factors, overall financial performance and other business or reporting unit-specific events that contribute to the fair value of a reporting unit. If the Company concludes, based on its qualitative assessment, it is more-likely-than-not (i.e., a likelihood of more than 50%) that a reporting unit’s fair value is higher than its carrying value, the Company is not required to perform any further goodwill impairment testing for that reporting unit. Otherwise, the Company proceeds to Step 1, and if a reporting unit’s fair value exceeds its carrying value, there is no impairment. A reporting unit with a carrying value in excess of its fair value results in an impairment charge equal to the difference.

The carrying values of goodwill and other indefinite-lived intangible assets are reviewed for impairment annually, as of October 1. An interim review is performed between annual tests if facts and circumstances indicate potential impairment. The carrying value of other amortizable intangible assets is reviewed if facts and circumstances indicate potential impairment. If a review indicates the carrying value is impaired, a charge is recorded equal to the amount by which the carrying value exceeds the fair value.

Retirement Plans and Postretirement Benefits. The Company sponsors defined benefit retirement plans and also provides other postretirement benefits. The Company recognizes the funded status, defined as the difference between the fair value of plan assets and the benefit obligation, of its pension plans and other postretirement benefits as an asset or liability on the consolidated balance sheets. Actuarial gains or losses that arise during the year are recognized as a component of accumulated other comprehensive earnings or loss. Those amounts are amortized over the participants’ average remaining service period and recognized as a component of net periodic benefit cost. The amount amortized is determined on a plan-by-plan basis using a corridor approach and represents the excess over 10% of the greater of the projected benefit obligation or pension plan assets.

Insurance Reserves. The Company has insurance coverage with large deductibles for workers’ compensation, automobile liability, marine liability and general liability claims, and is also self-insured for health claims. The Company records insurance reserves based on an actuarial-determined analysis, which calculates development factors that are applied to total case reserves within the insurance programs. While the Company believes the assumptions used to calculate these liabilities are appropriate, significant differences in actual experience and/or significant changes in these assumptions may materially affect insurance costs.

Stock-Based Compensation. The Company has stock-based compensation plans for employees and its Board of Directors. The Company recognizes all forms of stock-based awards that vest as compensation expense. The compensation expense is the fair value of the awards at the measurement date and is recognized over the requisite service period. Forfeitures are recognized as they occur.

The fair value of restricted stock awards, incentive compensation stock awards and Board of Directors’ fees paid in the form of common stock are based on the closing price of the Company’s common stock on the grant dates. The fair value of performance stock awards as of the grant dates is determined using a Monte Carlo simulation methodology.


Form 10-K ♦ Page 82

Part II ♦ Item 8 – Financial Statements and Supplementary Data

Environmental Matters. The Company records a liability for an asset retirement obligation at fair value in the period in which it is incurred. The asset retirement obligation is recorded at the acquisition date of a long-lived tangible asset if the fair value can be reasonably estimated. A corresponding amount is capitalized as part of the asset’s carrying amount. The fair value is affected by management’s assumptions regarding the scope of the work, inflation rates and asset retirement dates.

Further, the Company records an accrual for other environmental remediation liabilities in the period in which it is probable that a liability has been incurred and the appropriate amounts can be estimated reasonably. Such accruals are adjusted as further information develops or circumstances change. Generally, these costs 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.

Income Taxes. Deferred income taxes, net, on the consolidated balance sheets reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, net of valuation allowances. Deferred tax liabilities for property, plant and equipment result from accelerated depreciation methods being used for income tax purposes as compared with the straight-line method for financial reporting purposes. Deferred tax liabilities related to goodwill and other intangibles reflect the cessation of goodwill amortization for financial reporting purposes, while amortization continued for income tax purposes. The effect of changes in enacted tax rates on deferred income tax assets and liabilities is charged or credited to income tax expense in the period of enactment.

Uncertain Tax Positions. The Company recognizes a tax benefit when it is more-likely-than-not, based on the technical merits, that a tax position would be sustained upon examination by a taxing authority. The amount to be recognized is measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. The Company’s unrecognized tax benefits are recorded in other liabilities on the consolidated balance sheets or as an offset to the deferred tax asset for tax carryforwards where available.

The Company records interest accrued in relation to unrecognized tax benefits as income tax expense. Penalties, if incurred, are recorded as operating expenses in the consolidated statements of earnings.

Sales Taxes. The Company is deemed to be an agent when collecting sales taxes from customers. Sales taxes collected from customers are recorded as liabilities until remitted to taxing authorities and therefore are not reflected in the consolidated statements of earnings as revenues and expenses.

Start-Up Costs. Noncapital start-up costs for new facilities and products are charged to operations as incurred.

Consolidated Comprehensive Earnings and Accumulated Other Comprehensive Loss. Consolidated comprehensive earnings consist of consolidated net earnings, adjustments for the funded status of pension and postretirement benefit plans and foreign currency translation adjustments, and are presented in the Company’s consolidated statements of comprehensive earnings.

Accumulated other comprehensive loss consists of unrecognized gains and losses related to the funded status of the pension and postretirement benefit plans and foreign currency translation and is presented on the Company’s consolidated balance sheets.

Part II ♦ Item 8 – Financial Statements and Supplementary Data

Earnings Per Common Share. The Company computes earnings per common share (EPS) pursuant to the two-class method. The two-class method determines EPS for common stock and participating securities according to dividends or dividend equivalents and their respective participation rights in undistributed earnings. The Company paid nonforfeitable dividend equivalents during the vesting period on its restricted stock awards and incentive stock awards made prior to 2016, which results in these being considered participating securities.

The numerator for basic and diluted earnings per common share is net earnings attributable to Martin Marietta, reduced by dividends and undistributed earnings attributable to the Company’s participating securities. The denominator for basic earnings per common share is the weighted-average number of common shares outstanding during the period. Diluted earnings per common share is computed assuming that the weighted-average number of common shares is increased by the conversion, using the treasury stock method, of awards issued to employees and nonemployee members of the Company’s Board of Directors under certain stock-based compensation arrangements if the conversion is dilutive.

The following table reconciles the numerator and denominator for basic and diluted earnings from continuing operations per common share:


years ended December 31 (in millions)	2022		2021		2020
Net earnings from continuing operations attributable to Martin Marietta	$	856.3	$	702.0	$	721.0

Business Combinations

Total revenues and earnings from operations attributable to continuing operations acquired in 2021 (as subsequently described) included in the consolidated statement of earnings were $338.6 million and $12.1 million, respectively, for the year ended December 31, 2021. Total acquisition and integration expenses were $57.9 million for the year ended December 31, 2021 and were primarily related to the acquisition of Lehigh Hanson, Inc.'s West Region business (Lehigh West Region).

Lehigh West Region. In October 2021, the Company completed the acquisition of Lehigh West Region for $2.26 billion. The acquisition was primarily financed using proceeds from the issuance of publicly traded debt. These operations provided an upstream, materials-led growth platform across several of the nation’s largest and fastest-growing megaregions in California and

Arizona, solidifying the Company’s position as a leading coast-to-coast aggregates producer. The results from the acquired business are included in the Company’s West Group.

The Company determined the acquisition-date fair values of assets acquired and liabilities assumed. Notably, during the year ended December 31, 2022, the Company reduced the acquisition-date fair value of intangible assets, other than goodwill, by $119.5 million; increased the acquisition-date fair value of asset retirement obligations and other liabilities assumed by $115.7 million; and increased goodwill by $233.1 million. As of December 31, 2022, the measurement period is closed. The following is a summary of the fair values of the assets acquired and the liabilities assumed as of the acquisition date:

Amortization of the goodwill generated by the transaction is deductible for income tax purposes.

The following unaudited pro forma financial information summarizes the combined results of operations for the Company and Lehigh West Region as though the companies were combined as of January 1, 2020. Financial information for periods prior to the October 1, 2021 acquisition date included in the pro forma earnings does not reflect any cost savings or associated costs to achieve such savings from operating efficiencies or synergies that may result from the combination. Consistent with the assumed acquisition date of January 1, 2020, the pro forma financial results for the year ended December 31, 2020 include acquisition and integration expenses of $46.8 million.

The unaudited pro forma financial information does not purport to project the future financial position or operating results of the combined company. The following pro forma financial information is for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place as of January 1, 2020:

The pro forma financial information excludes the acquired cement and California ready mix businesses, which were classified as assets held for sale and reported as discontinued operations as of and for the year ended December 31, 2021.

Southern Crushed Concrete. In July 2021, the Company acquired the assets of Southern Crushed Concrete (SCC), a leading producer in the Houston area of recycled concrete, which is principally used as a base aggregates product in infrastructure, commercial and residential construction applications. The Company determined the acquisition-date fair values of the assets acquired and liabilities assumed. Notably, during the year ended December 31, 2022, the Company reduced the acquisition-date fair value of intangible assets, other than goodwill, by $64.0 million and increased goodwill by $64.7 million. As of December 31, 2022, the measurement period is closed. Amortization of the goodwill generated by the transaction is deductible for income tax purposes.

Tiller Corporation. In April 2021, the Company completed the acquisition of Tiller Corporation (Tiller), a leading aggregates and hot mix asphalt supplier in the Minneapolis/St. Paul region, one of the largest and fastest-growing midwestern metropolitan areas. The Tiller acquisition complemented the Company’s existing product offerings in the surrounding areas. The Company determined the acquisition-date fair values of the assets acquired and liabilities assumed. As of December 31, 2022, the measurement period is closed. Amortization of the goodwill generated by the transaction is deductible for income tax purposes. The results from the acquired business are reported in the Company’s East Group and are immaterial for pro forma financial statement disclosures.

Divestitures

On August 9, 2022, the Company announced a definitive agreement to sell its Tehachapi, California cement plant and related distribution terminals for $350.0 million in cash, subject to regulatory approval and customary closing conditions. These operations are classified as assets held for sale and reported as discontinued operations as of and for the years ended December 31, 2022 and 2021.

In June 2022, the Company completed the sale of the Redding, California cement plant, related cement distribution terminals and 14 California ready mix operations for $235.0 million in cash. In addition, on July 15, 2022, the Company sold its interest in a joint venture that operates a cement distribution terminal for $15.0 million. These businesses were previously classified as assets held for sale.

In April 2022, the Company divested its Colorado and Central Texas ready mixed concrete operations to Smyrna Ready Mix Concrete LLC. This transaction optimized the Company's aggregates-led portfolio and improved its ability to generate more attractive margins over the long term by reducing both business cyclicality and exposure to raw material cost inflation. The transaction resulted in a pretax gain of $151.9 million, which is included in Other operating income, net, on the Company's consolidated statement of earnings for the year ended December 31, 2022 and is inclusive of expenses incurred due to the divestiture. The divested operations and the gain on divestiture are all reported in the West Group.

Discontinued Operations

Discontinued operations are comprised of the cement and California ready mix businesses acquired as part of the Lehigh West Region transaction. Financial results for the Company's discontinued operations were as follows:


years ended December 31 (in millions)	2022			2021

On September 29, 2022, the Company satisfied and discharged the 0.650% Senior Notes, which were issued in July 2021. In connection with the satisfaction and discharge, the Company irrevocably deposited funds with Regions Bank, as trustee under the indenture governing the 0.650% Senior Notes, in an amount sufficient to satisfy all remaining principal and interest payments on the 0.650% Senior Notes. Holders of the 0.650% Senior Notes will receive payment of principal on the scheduled maturity date and payment of interest at the per annum rate (and on the dates) set forth in the 0.650% Senior Notes indenture. The Company utilized existing cash resources to fund the satisfaction and discharge. As a result of the satisfaction and discharge, the obligations of the Company under the indenture with respect to the 0.650% Senior Notes have been terminated, except those provisions of the indenture that, by their terms, survive the satisfaction and discharge. Because the discharge did not represent a legal defeasance, the 0.650% Senior Notes remain on the Company's consolidated balance sheet at December 31, 2022 and will continue to accrete to their par value over the period until maturity in July 2023. Additionally, the related trust assets are included in Restricted investments (to satisfy discharged debt and related interest) on the Company's consolidated balance sheet at December 31, 2022.

In July 2021, the Company issued the 0.650% Senior Notes, $900.0 million aggregate principal amount of 2.400% Senior Notes due 2031 (the 2.400% Senior Notes) and $900.0 million aggregate principal amount of 3.200% Senior Notes due 2051 (the 3.200% Senior Notes). The Company used the net proceeds to pay the consideration for the acquisition of the Lehigh West Region business and for general corporate purposes. See Note C for more information on the Lehigh West Region acquisition.

The Company’s 4.250% Senior Notes due 2024, 7% Debentures due 2025, 3.450% Senior Notes due 2027, 3.500% Senior Notes due 2027, 2.500% Senior Notes due 2030, 2.400% Senior Notes due 2031, 6.25% Senior Notes due 2037, 4.250% Senior Notes due 2047 and 3.200% Senior Notes due 2051 (collectively, the Senior Notes) are senior unsecured obligations of the Company, ranking equal in right of payment with the Company’s existing and future unsubordinated indebtedness. The Senior Notes, with the exception of the 7% Debentures due 2025 and the 6.25% Senior Notes due 2037, are redeemable prior to their respective par call dates, as defined, at a make-whole redemption price, and at a price equal to 100% of the principal amount after their respective par call dates and prior to their respective maturity dates. The 6.25% Senior Notes due 2037 are redeemable in whole at any time or in part from time to time at a make-whole redemption price. Upon a change-of-control repurchase event and a resulting below-investment-grade credit rating, the Company would be required to make an offer to repurchase all outstanding Senior Notes, with the exception of the 7% Debentures due 2025, at a price in cash equal to 101% of the principal amount of the Senior Notes, plus any accrued and unpaid interest.

During the year ended December 31, 2022, the Company repurchased $67.7 million (par value) of it Senior Notes.

The Company has a credit agreement with JPMorgan Chase Bank, N.A., as Administrative Agent, Deutsche Bank Securities, Inc., PNC Bank, Truist Bank and Wells Fargo Bank, N.A., as Syndication Agents, and the lenders party thereto (the Credit Agreement), which provides for a $800.0 million five-year senior unsecured revolving facility (the Revolving Facility). Borrowings under the Revolving Facility bear interest, at the Company’s option, at rates based upon the Secured Overnight Financing Rate (SOFR) or a base rate, plus, for each rate, a margin determined in accordance with a ratings-based pricing grid. There were no borrowings outstanding under the Credit Agreement as of December 31, 2022 and 2021. On December 22, 2022, the Company amended the Credit Agreement to replace the London InterBank Offered Rate (LIBOR) with SOFR as the interest rate benchmark and extend the maturity date to December 21, 2027. Any outstanding principal amounts, together with interest accrued thereon, are due in full on that maturity date. Available borrowings under the Revolving Facility are reduced by any outstanding letters of credit issued by the Company under the Revolving Facility. At December 31, 2022 and 2021, the Company had $2.6 million of outstanding letters of credit issued and $797.4 million available for borrowing under the Revolving Facility. The Company paid the bank group an upfront loan commitment fee that is being amortized over the life of the Revolving Facility. The Revolving Facility includes an annual facility fee.

The Credit Agreement requires the Company’s ratio of consolidated net debt-to-consolidated earnings before interest, taxes, depreciation, depletion and amortization, as defined, for the trailing-twelve months (the Ratio) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Company may exclude from the Ratio any debt incurred in connection with certain acquisitions during the quarter or three preceding quarters so long as the Ratio calculated without such exclusion does not exceed 4.00x. Additionally, if no amounts are outstanding under the Revolving Facility or the Company's trade receivable securitization facility (discussed later), consolidated debt, as defined, which includes debt for which the Company is a guarantor (see Note O), shall be reduced in an amount equal to the lesser of $500.0 million or the sum of the Company’s unrestricted cash and temporary investments, for purposes of the covenant calculation. The Company was in compliance with the Ratio at December 31, 2022.

The Company, through a wholly-owned special-purpose subsidiary, has a $400.0 million trade receivable securitization facility (the Trade Receivable Facility). On September 21, 2022, the Company extended the maturity to September 20, 2023. The Trade Receivable Facility, with Truist Bank, Regions Bank, PNC Bank, N.A., MUFG Bank, Ltd., New York Branch, and certain other lenders that may become a party to the facility from time to time, is backed by eligible trade receivables, as defined. Borrowings are limited to the lesser of the facility limit or the borrowing base, as defined. These receivables are originated by the Company and then sold or contributed to the wholly-owned special-purpose subsidiary. The Company continues to be responsible for the servicing and administration of the receivables purchased by the wholly-owned special-purpose subsidiary. Borrowings under the Trade Receivable Facility bear interest at a rate equal to asset-backed commercial paper costs of conduit lenders plus 0.65% for borrowings funded by conduit lenders and Adjusted Term Secured Overnight Financing Rate (Adjusted Term SOFR), as defined, plus 0.7%, subject to change in the event that this rate no longer reflects the lender’s cost of lending, for borrowings funded by all other lenders. The Trade Receivable Facility contains a cross-default provision to the Company’s other debt agreements. Subject to certain conditions, including lenders providing the requisite commitments, the Trade Receivable Facility may be increased to a borrowing base not to exceed $500 million. At December 31, 2022 and 2021, there were no borrowings outstanding under the Trade Receivable Facility.

For the years ended December 31, 2022, 2021 and 2020, there was a foreign pretax loss of $2.3 million, and earnings of $7.5 million and $8.9 million, respectively.

The Company’s effective income tax rate on continuing operations varied from the statutory United States income tax rate because of the following tax differences:


years ended December 31	2022			2021			2020
Statutory income tax rate		21.0	%		21.0	%		21.0	%
(Reduction) increase resulting from:
Effect of statutory depletion		(2.4	)		(3.5	)		(2.8	)
State income taxes, net of federal tax benefit		2.9			2.3			2.6
Federal tax credits		(0.9	)		(1.4	)		(1.3	)
Other items		0.9			(0.5	)		(0.6	)
Effective income tax rate		21.5	%		17.9	%		18.9	%

The higher 2022 effective tax rate versus 2021 and 2020 was primarily driven by the impact of the divestiture of the Colorado and Central Texas ready mixed concrete businesses.

The statutory depletion deduction for all years is calculated as a percentage of sales, subject to certain limitations. Due to these limitations, the impact of changes in the sales volumes and earnings may not proportionately affect the Company’s statutory depletion deduction and the corresponding impact on the effective income tax rate.

In 2022, 2021 and 2020, the Company financed third-party railroad track maintenance. In exchange, the Company received federal income tax credits and tax deductions.

The Company had $1.3 million of domestic federal net operating loss (NOL) carryforwards at December 31, 2022 and 2021. The Company had domestic state NOL carryforwards of $55.3 million and $40.7 million at December 31, 2022 and 2021, respectively. These carryforwards have various expiration dates through 2042. At December 31, 2022 and 2021, deferred tax assets associated with these carryforwards were $3.6 million and $2.6 million, respectively, net of the federal benefit of the state deduction, for which valuation allowances of $2.1 million and $2.2 million, respectively, were recorded. The Company also had domestic state tax credit carryforwards of $1.3 million and $0.9 million at December 31, 2022 and 2021, respectively, which have various expiration dates through 2042. At December 31, 2022 and 2021, deferred tax assets associated with these carryforwards were $1.0 million and $0.7 million, respectively, net of the federal benefit of the state deduction.

The Company expects to reinvest the earnings from its wholly-owned Canadian and Bahamian subsidiaries indefinitely, and accordingly, has not provided deferred taxes on the subsidiaries’ undistributed net earnings or basis differences. The Company believes that the tax liability that would be incurred upon repatriation was immaterial at December 31, 2022 and 2021.

The following table summarizes the Company’s unrecognized tax benefits, excluding interest and correlative effects of $0.2 million for the years ended December 31, 2022, 2021 and 2020:


years ended December 31 (in millions)	2022			2021			2020

Unrecognized tax benefits are reversed as a discrete event if an examination of applicable tax returns is not initiated by a federal or state tax authority within the statute of limitations or upon effective settlement with federal or state tax authorities. For the year ended December 31, 2022, $2.1 million was reversed into income upon the statute of limitations expiration for 2018. For the year ended December 31, 2021, $1.6 million was reversed into income upon the statute of limitations expiration for 2017. For the


Form 10-K ♦ Page 96

Part II ♦ Item 8 – Financial Statements and Supplementary Data

year ended December 31, 2020, $9.7 million was reversed into income upon the statute of limitations expiration for 2016 and all prior open tax years. Management believes its accrual for unrecognized tax benefits is sufficient to cover uncertain tax positions reviewed during audits by taxing authorities.

The Company anticipates that it is reasonably possible that its unrecognized tax benefits may decrease up to $2.0 million, excluding interest and correlative effects, during the twelve months ending December 31, 2023, due to the expiration of the statutes of limitations for the 2019 tax year.

The Company’s tax years subject to federal, state or foreign examinations are 2018 through 2022.

Note K: Retirement Plans, Postretirement and Postemployment Benefits

The Company sponsors defined benefit retirement plans that cover substantially all employees. Additionally, the Company provides other postretirement benefits for certain employees, including medical benefits for retirees and their spouses and retiree life insurance. Employees starting on or after January 1, 2002 are not eligible for postretirement welfare plans. The Company also provides certain benefits, such as disability benefits, to former or inactive employees after employment but before retirement.

The measurement date for the Company’s defined benefit plans, postretirement benefit plans and postemployment benefit plans is December 31. During 2022, the Company amended its qualified pension plan to provide an enhanced benefit for eligible hourly active participants who retire subsequent to April 30, 2022, which resulted in a remeasurement of the qualified pension plan as of February 28, 2022. The remeasurement increased the defined benefit plans’ unrecognized prior service cost by $47.6 million.

Defined Benefit Retirement Plans. Defined retirement benefits for salaried employees are based on each employee’s years of service and average compensation for a specified period of time before retirement. Defined retirement benefits for hourly employees are generally stated amounts for specified periods of service.

The Company sponsors a Supplemental Excess Retirement Plan (SERP) that generally provides for the payment of retirement benefits in excess of allowable Internal Revenue Code limits. The SERP generally provides for a lump-sum payment of vested benefits. When these benefit payments exceed the sum of the service and interest costs for the SERP during a year, the Company recognizes a pro rata portion of the SERP’s unrecognized actuarial loss as settlement expense.

The net periodic benefit cost of defined benefit plans includes the following components:


years ended December 31 (in millions)	2022			2021			2020
Service cost	$	48.1		$	46.2		$	39.2
Interest cost		41.2			35.7			37.1
Expected return on assets		(77.3	)		(70.5	)		(58.4	)
Amortization of:
Prior service cost		4.9			0.8			0.7
Actuarial loss		3.9			12.2			14.5
Settlement charge		4.6			—			3.7
Net periodic benefit cost	$	25.4		$	24.4		$	36.8

The components of net periodic benefit cost, other than service cost, are included in the line item Other nonoperating income, net, in the consolidated statements of earnings. Based on the roles of the employees, service cost is included in Cost of revenues – products and services or Selling, general and administrative expenses line items in the consolidated statements of earnings.

The expected return on assets is calculated by applying an annually selected expected long-term rate of return assumption to the estimated fair value of the plan assets during the year, giving consideration to contributions and benefits paid.

	2022	2021
Discount rate	5.88%	3.23%
Rate of increase in future compensation levels	4.50%	4.50%

Weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31 are:


	2022	2021	2020
Discount rate	3.44%	3.16%	3.69%
Rate of increase in future compensation levels	4.50%	4.50%	4.50%
Expected long-term rate of return on assets	6.75%	6.75%	6.75%

The expected long-term rate of return on assets is based on a building-block approach, whereby the components are weighted based on the allocation of pension plan assets.

As of December 31, 2022 and 2021, the Company estimated the remaining lives of participants in the pension plans using the Pri-2012 Base tables. The no-collar table was used for salaried participants and the blue-collar table was used for hourly participants; both tables were adjusted to reflect the experience of the Company’s participants. The Company used the MP-2020 mortality improvement scale for the years 2022 and 2021.

Retirement plan assets are invested in listed stocks, bonds, real estate, private infrastructure and cash equivalents. The target allocation for 2022 and the actual pension plan asset allocation by asset class are as follows:


	Percentage of Plan Assets
		2022
		Target	December 31
Asset Class		Allocation	2022	2021

Real estate		10%	14%	7%
Private infrastructure		6%	8%	7%
Total		100%	100%	100%

The Company’s investment strategy is for equity securities to be invested in mid-sized to large capitalization U.S. funds, and small capitalization, international and emerging growth funds. Debt securities, or fixed income investments, are invested in funds benchmarked to the Barclays U.S. Aggregate Bond Index.

These investments are common collective investment trusts valued using the net asset value (NAV) unit price provided by the fund administrator. The NAV is based on the value of the underlying assets owned by the fund.

Real estate investments are stated at estimated fair value, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Real estate investments are valued at NAV based on the plan’s proportionate shares of the real estate funds’ fair value as recorded by the trustees/general partner of the funds. The funds are real estate investment trust based funds that offer participation in an actively managed, primarily core portfolio of equity real estate. The funds allocate gains, losses and expenses to investors based on the ownership percentage to determine the NAV. Private infrastructure assets represent investments in a fund that is stated at fair value. For financial assets in the fund that are actively traded in organized financial markets, fair value is based on exchange-quoted market prices. For investments in a fund for which there is no quoted market price, fair value is determined by the trustees/general partner of the fund based on discounted expected future cash flows prepared by third-party professionals. The value of hedge funds is based on the values of the sub-fund investments. In determining the fair value of each sub-fund’s investment, the hedge funds’ board of trustees uses the values provided by the sub-funds and any other considerations that may, in its judgment, increase or decrease such estimated value.

In 2022 and 2021, the Company made combined pension plan and SERP contributions of $90.2 million and $82.8 million, respectively. The Company currently estimates that it will contribute $36.5 million to its pension plans in 2023.

Stock-Based Award Plan, as amended from time to time, along with the Amended Omnibus Securities Award Plan, originally approved in 1994 (collectively, the Plans), are still effective for awards made prior to 2017. The Company has been authorized by the Board of Directors to repurchase shares of the Company’s common stock for issuance under the stock-based award plans (see Note N).

The Company grants restricted stock awards under the Plans to a group of executive officers, key personnel and nonemployee members of the Board of Directors. The vesting of certain restricted stock awards is based on certain performance criteria over a specified period of time. The number of shares may be increased to the maximum or reduced to the minimum threshold based on the results of those criteria. In addition, certain awards are granted to individuals to encourage retention and motivate key employees. These awards generally vest if the employee is continuously employed over a specified period of time and require no payment from the employee. Awards granted to nonemployee members of the Board of Directors vest immediately.

The fair value of stock-based award grants is expensed over the vesting period. Awards to employees eligible for retirement prior to the award becoming fully vested are expensed over the period through the date that the employee first becomes eligible to retire and is no longer required to provide service to earn the award. Awards granted to nonemployee members of the Board of Directors are expensed immediately.

Additionally, an incentive compensation stock plan has been adopted under the Plans whereby certain participants may elect to use up to 50% of their annual incentive compensation to acquire units representing shares of the Company’s common stock at a 20% discount to the market value on the date of the incentive compensation award. Participants receive unrestricted shares of common stock in an amount equal to their respective units generally at the end of a 34-month period of additional employment from the date of award or at retirement beginning at age 62. All rights of ownership of the common stock convey to the participants upon the issuance of their respective shares at the end of the ownership-vesting period.

The following table summarizes information for restricted stock awards and incentive compensation stock awards for 2022:


	Restricted Stock - Service Based					Restricted Stock - Performance Based					Incentive Compensation Stock

The weighted-average grant-date fair value of service-based restricted stock awards granted during 2022, 2021 and 2020 was $362.77, $342.11 and $222.39, respectively. The weighted-average grant-date fair value of performance-based restricted stock awards granted during 2022, 2021 and 2020 was $406.99, $352.52 and $266.97, respectively. The weighted-average grant-date fair value of incentive compensation stock awards granted during 2022, 2021 and 2020 was $369.05, $325.30 and $258.67, respectively.

The aggregate intrinsic values for unvested restricted stock awards and unvested incentive compensation stock awards at December 31, 2022 were $108.0 million and $2.1 million, respectively, and were based on the closing price of the Company’s common stock at December 31, 2022, which was $337.97. The aggregate intrinsic values of restricted stock awards distributed during the years ended December 31, 2022, 2021 and 2020 were $64.5 million, $41.1 million and $35.2 million, respectively.

and 2020 were $3.1 million, $4.9 million and $1.7 million, respectively. The aggregate intrinsic values for distributed awards were based on the closing prices of the Company’s common stock on the dates of distribution.

Prior to 2016, under the Plans, the Company granted options to employees to purchase its common stock at a price equal to the closing market value at the date of grant. Options become exercisable in four annual installments beginning one year after date of grant. Options granted starting in 2013 expire ten years after the grant date, while outstanding options granted prior to 2013 expire eight years after the grant date.

The following table includes summary information for stock options as of December 31, 2022:


	Number of Options			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life (years)
Outstanding at January 1, 2022		20,564		$	133.59
Exercised		(5,281	)	$	125.02
Outstanding at December 31, 2022		15,283		$	136.55		1.8

Exercisable at December 31, 2022		15,283		$	136.55		1.8

The aggregate intrinsic values of options exercised during the years ended December 31, 2022, 2021 and 2020 were $1.3 million, $2.3 million and $3.3 million, respectively, and were based on the closing prices of the Company’s common stock on the dates of exercise. The aggregate intrinsic values for options outstanding and exercisable at December 31, 2022 were $3.1 million and were based on the closing price of the Company’s common stock at December 31, 2022, which was $337.97.

At December 31, 2022, there were approximately 0.5 million awards available for grant under the Plans. In 2016, the Company’s shareholders approved the issuance of an additional 0.8 million shares of common stock under the Plans.

In 1996, the Company adopted the Shareholder Value Achievement Plan to award shares of the Company’s common stock to key senior employees based on certain common stock performance criteria over a long-term period. Under the terms of this plan, 0.3 million shares of common stock were reserved for issuance. Through December 31, 2022, 42,025 shares have been issued under this plan. No awards have been granted under this plan since 2000.

The Company adopted and the shareholders approved the Common Stock Purchase Plan for Directors in 1996, which provides nonemployee members of the Board of Directors the election to receive all or a portion of their total fees in the form of the Company’s common stock. Beginning in 2016, members of the Board of Directors were not required to defer any of their fees in the form of the Company’s common stock. Under the terms of this plan, 0.3 million shares of common stock were reserved for issuance. Nonemployee members of the Board of Directors elected to defer portions of their fees representing 1,767, 1,686 and 3,043 shares of the Company’s common stock under this plan during 2022, 2021 and 2020, respectively.

Consolidated earnings from operations include total revenues less cost of revenues; selling, general and administrative expenses; acquisition and integration expenses; other operating income and expenses, net; and exclude interest expense; other nonoperating income and expenses, net; and income tax expense. Corporate loss from operations primarily includes depreciation; expenses for corporate administrative functions; acquisition and integration expenses; and other nonrecurring income and expenses not attributable to operations of the Company's other operating segments. All long-term debt and related interest expense are held at Corporate.

Assets employed by segment include assets directly identified with those operations. Corporate assets consist primarily of cash, cash equivalents and restricted cash; property, plant and equipment for corporate operations; restricted investments; and other assets not directly identifiable with a reportable segment.

Part II ♦ Item 9 – Changes In and Disagreements with Accountants on Accounting and Financial Disclosure

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

As of December 31, 2022, 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. Based on that evaluation, the Company’s CEO and CFO concluded that the Company’s disclosure controls and procedures were effective at the reasonable assurance level.

The foregoing evaluation of the Company’s disclosure controls and procedures was based on the definition in Exchange Act Rule 13a-15(e), which requires that disclosure controls and procedures are effectively designed to provide reasonable assurance that information required to be disclosed by an issuer in the reports that it files or submits with the SEC under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Our management’s report on internal control over financial reporting is included as the “Statement of Financial Responsibility and Management’s Report on Internal Controls over Financial Reporting” in Item 8, “Financial Statements and Supplemental Data,” of this Form 10-K. The Company’s management 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, 2022. PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited the Company’s consolidated financial statements contained herein, also audited the Company’s internal control over financial reporting as of December 31, 2022. The audit report is included in Item 8, “Financial Statements and Supplementary Data,” of this Form 10-K.

There were no changes in the Company’s internal control over financial reporting during the most recently completed fiscal quarter ended December 31, 2022 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

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 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, controls 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.
