Martin Marietta Materials, Inc.

2.500% Senior Notes due 2030

Martin Marietta Materials, Inc. is offering $500,000,000 aggregate principal amount of its 2.500% Senior Notes due 2030 (the “notes”). The notes will accrue interest from, and including, March 16, 2020 at a per annum rate of 2.500%, and will be payable in arrears on March 15 and September 15 of each year, beginning on September 15, 2020. The notes will mature on March 15, 2030.

We have the option to redeem some or all of the notes prior to their stated maturity date at any time and from time to time, as described under the heading “Description of the notes—Optional redemption.” If a Change of Control Repurchase Event (as defined herein) occurs, we will be required to offer to repurchase all of the outstanding notes at a repurchase price equal to 101% of their principal amount, plus unpaid interest, if any, accrued thereon to, but excluding, the date of repurchase, unless we have exercised our right to redeem the notes in full. See “Description of the notes—Change of Control Repurchase Event.”

The notes will be our senior unsecured obligations, will rank equally in right of payment with all of our existing and future senior indebtedness and will rank senior in right of payment to all of our future subordinated indebtedness. The notes will be effectively subordinated to all of our existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. The notes will not be guaranteed by any of our subsidiaries and will be structurally subordinated to all of the existing and future indebtedness and other liabilities (including trade accounts payable) and preferred equity of our subsidiaries.

Investing in the notes involves risks. See “Risk factors” beginning on page S-15 for a discussion of certain risks that you should consider in connection with an investment in the notes.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the notes or determined if this prospectus supplement or the accompanying base prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

We do not intend to apply to list the notes on any securities exchange or to arrange for the notes to be quoted on any automated interdealer quotation system.

We expect to deliver the notes to investors through the book-entry delivery system of The Depository Trust Company and its direct participants, including Euroclear Bank S.A./N.V. and Clearstream Banking, société anonyme, against payment, on or about March 16, 2020.

About this prospectus supplement and the accompanying base prospectus

This document is in two parts. The first part is the prospectus supplement, which describes the specific terms of the notes being offered and also adds to and updates information contained in the accompanying base prospectus. The second part, the base prospectus, gives more general information, some of which may not apply to the notes being offered. Generally, when we refer only to the “prospectus,” we are referring to both parts combined, and when we refer to the “base prospectus,” we are referring only to the base prospectus.

If the information contained or incorporated by reference in this prospectus supplement varies in any way from the information contained or incorporated by reference in the accompanying base prospectus, you should rely on the information contained or incorporated by reference in this prospectus supplement. If the information contained in this prospectus supplement varies in any way from the information incorporated by reference herein, you should rely on the more recent document.

This prospectus and the documents incorporated by reference herein may include market share, ranking, industry data and forecasts that we obtained from industry publications, surveys, public filings and internal company sources. Industry publications, surveys and forecasts generally state that the information contained therein has been obtained from sources believed to be reliable, but there can be no assurance as to the accuracy or completeness of included information. We have not independently verified any of the data from third-party sources, nor have we ascertained the underlying economic assumptions relied upon therein. Statements as to our market position and ranking are based on market data currently available to us, management’s estimates and assumptions we have made regarding the size of our markets within our industry. Some market data and statistical information are also based on our good faith estimates, which are derived from management’s knowledge of our industry and independent sources. This information may prove to be inaccurate because of the method by which we obtain some of the data for our estimates or because this information cannot always be verified with complete certainty due to the limits on the availability and reliability of data and other limitations and uncertainties. In addition, while we believe the market position and ranking information included or incorporated by reference herein is generally reliable, such information is inherently imprecise. While we are not aware of any misstatements regarding our industry data presented or incorporated by reference herein, our estimates involve risks and uncertainties and are subject to change based on various factors, including those discussed under the heading “Risk factors” in this prospectus and in our Annual Report on Form 10-K for the year ended December 31, 2019 incorporated by reference herein. Certain numerical figures set forth in this prospectus have been subject to rounding adjustments.

We expect that delivery of the notes will be made to investors on or about March 16, 2020, which will be the seventh business day following the date of this prospectus supplement (such settlement cycle being referred to as “T + 7”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the second business day before delivery will be required, by virtue of the fact that the notes initially settle in T + 7, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to the second business day preceding the delivery date of the notes should consult their advisors.

It is important for you to read and consider all information contained in this prospectus supplement, each related free writing prospectus, if any, the accompanying base prospectus and the documents they incorporate by reference in making your investment decision.

Risks related to our business

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

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 hurt 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 products, our primary business, and our cement products to the construction industry, so 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, demographic and population shifts and changes in construction spending by federal, state and local governments. If economic conditions change, a recession in the construction industry may occur and affect the demand for our products. The Recession of the late 2000’s and early 2010’s (the “Great Recession”) was an example, and our shipment volumes were significantly reduced. 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 because of the high cost to transport our products relative to their price. If economic conditions and construction spending decline significantly in one or more areas, particularly in our top five revenue-generating states of our Building Materials business of Texas, Colorado, North Carolina, Georgia and Iowa, our profitability will decrease. We experienced this situation with the Great Recession.

The Great Recession resulted in large declines in shipments of aggregates products in our industry. Recent years, however, have shown a slow-but-steady turnaround in this trend. The current economic expansion in the United States, which began in 2009, has now become the longest economic recovery in United States history; however, there is no guarantee that this expansion will continue. For example, disruptions in economic activity resulting from the recent outbreak of the coronavirus (COVID-19), which first emerged in China and has expanded globally, may have an adverse impact on our industry, our supply chain and/or our workforce.

While historical spending on public infrastructure projects has been, comparatively, more stable as governmental appropriations and expenditures are typically less interest rate-sensitive than private sector spending, we experienced a slight retraction in aggregates product line shipments to the infrastructure market

S-15

after uncertainty regarding the passage of a federal highway bill in 2014. Contractors were not able to get any long-term certainty on the availability of federal infrastructure funding until late 2015 with the enactment of a new federal highway bill.

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 and heavy or sustained rainfall, 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. The Building Materials product lines’ production and shipment levels follow activity in the construction industry, which typically are 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 the Company’s Building Materials business, including all of its 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, while the first and fourth quarters are subject to the impacts of winter weather, and thus are generally the least profitable. Weather-related hindrances were exacerbated over the last few years by record precipitation in many of our key markets, notably the eastern seaboard and Texas. Importantly, inclement weather was most significant during the second and third quarters, which represents the height of the construction season. These weather events reduced the Company’s overall profitability in the last few years, so our results for those years, or in comparison to other years, may not be indicative of our future operating results. 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. In 2019, Hurricane Dorian and Tropical Storm Imelda temporarily disrupted the Company’s business.

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

Our challenge is to find aggregates deposits that we can mine economically, with appropriate permits, near either growing markets or long-haul transportation corridors that economically serve growing markets. As communities have grown, they have taken up attractive quarrying locations and have imposed restrictions on mining. We try to meet this challenge by identifying and permitting sites prior to economic expansion, buying more land around our existing quarries to increase our mineral reserves, developing underground mines, and developing a distribution network that transports aggregates products by various 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.

Our businesses face many competitors.

Our businesses have many competitors, some of whom are bigger and have more resources than we do. Some of our competitors 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

S-16

products that could be used instead of our magnesia-based products. As other examples, our aggregates, ready mix concrete and asphalt and paving product lines may compete with recycled asphalt and concrete products that could be used instead of new products and our cement product line may compete with international competitors who are importing products to the United States with lower production and regulatory costs.

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

We expect to continue to grow, in part, by buying other businesses. We will continue to look for strategic businesses to acquire, like our acquisition of Texas Industries, Inc. (“TXI”) in 2014 and our acquisition of Bluegrass in 2018. 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. 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 of 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. Our largest business acquisition was TXI, which closed in July 2014. In 2015, we completed the integration of TXI’s operations into our own operations ahead of schedule, which allowed us to achieve and exceed the synergies, cost savings and operating efficiencies we had forecasted at the time of the acquisition. In 2018, we completed the integration of the operations of Bluegrass into our own operations in a manner that surpassed the publicly stated synergy estimates provided at the closing of the transaction. 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 other significant business acquisition or combination we might choose to do, similar to the acquisition of TXI or Bluegrass, would 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:

S-17

Our acquisitions could harm our results of operations.

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

Our cement product line and Magnesia Specialties business may become capacity-constrained.

If our cement product line or Magnesia Specialties business becomes capacity-constrained, they may be unable to timely satisfy the demand for some of their 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 further our manufacturing capacity, 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. Capacity constraints may prevent us from satisfying customer orders and result in a loss of sales to competitors that are not capacity-constrained. In addition, we may suffer excess capacity if we increase our capacity to meet actual or anticipated demand and that demand decreases or does not materialize. While we are permitted to expand production by up to 800,000 additional tons at our Midlothian cement plant, it could take us a significant period of time before such production expansion could come to fruition.

S-18

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

The cement industry has in the past obtained antidumping orders imposing duties on imports of cement and clinker from other countries that violated U.S. fair trade laws. Currently, an antidumping order against cement and clinker from Japan is set to expire but is under review for extension by the Federal Trade Commission. As has always been the case, 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 greenhouse gases (“GHG”)) and water discharges, waste management, noise and dust control, 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. 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 for 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, products, hazardous substances and wastes. We are exposed to hazards including storage tank leaks, explosions, discharges or releases of hazardous substances, exposure to dust and the operation of mobile equipment and manufacturing machinery.

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

We are involved from time to time in litigation and claims arising from our operations. While we do not believe the outcome of pending or threatened litigation will have a material adverse effect on our operations or our financial condition, an unexpected and material adverse outcome in a pending or future legal action could potentially have a negative effect on our Company.

S-19

Climate change and related legislation or regulations may adversely impact our business, including potential physical and financial impacts.

Amid concerns that GHG emissions are contributing to climate change, 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 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 U.S., 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. Although the U.S. Supreme Court subsequently ruled in June 2014 that the USEPA exceeded its statutory authority in issuing the Tailoring Rule, the Court upheld the so-called “Best Available Control Technology” requirements for GHGs emitted by sources that already require Title V operating permits or are subject to PSD requirements for other pollutants. Thus, 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.

Although the operations of the Company’s aggregates, ready mixed concrete and asphalt and paving product lines are not major sources of GHG emissions, any additional regulatory restrictions on emissions of GHGs imposed by the USEPA will likely impact the Company’s magnesia-based chemicals operations in Woodville, Ohio and Manistee, Michigan, as well as its two cement plants in Texas, each of which file annual reports of GHG emissions as required by the USEPA reporting rule. It is not possible, however, to estimate the cost of any such future requirements at this time. In addition, the Company may not be able to recover any increased operating costs or taxes relating to GHG emission limitations at those plants from its customers in order to remain competitive in pricing in the relevant markets.

In addition to impacts from increased GHG and other climate-related regulation, climate change may result in physical and financial impacts that could have adverse effects on the Company’s operations or financial condition. Given the nature of our operations, 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 and cement operations correlate with general construction activity, 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. Excessive rainfall and other severe weather events also jeopardize production, 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, most notably in August, September and October. The last few years brought an unprecedented amount of precipitation to the United States and particularly to Texas and the southeastern United States. In addition, climate and inclement weather can reduce the useful life of an asset.

Our businesses also are dependent on reliable sources of electricity and fuels. We could incur increased costs or disruptions in our operations if climate change legislation and regulation or severe weather impacts the price or availability of purchased electricity or fuels or other materials used in our operations. These and other climate-related risks also could impact our customers, such as a downturn in the construction sector, which could lead to reduced demand for our products. The Company may not be able to pass on to its customers all the costs related to mitigating these risks.

S-20

The overall impacts of climate change on our operations and the Company are highly uncertain and difficult to estimate. However, climate change legislation and regulation concerning GHGs could have a material adverse effect on our future financial position, results of operations or cash flows.

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 current federal highway bill, the Fixing America’s Surface Transportation Act (the “FAST Act”), which reauthorized federal highway and transportation funding programs. The FAST Act, however, only reauthorized federal infrastructure funding through 2020, so it must be reauthorized this year. If not reauthorized this year, the Company anticipates some level of funding would be continued with continuing resolutions. The uncertainty of federal funding has led to the increase in state and alternative methods of infrastructure funding. We expect to see increased infrastructure spending at the state level in 2020. At the federal level, we expect to see some increased infrastructure spending in 2020 resulting from the FAST Act funding, but will be dependent on a successor FAST Act bill or continuing resolutions in the future for any greater federal impact on funding. Any enhanced federal infrastructure bill will require Congressional approval. We cannot be assured, however, of such approval or of the existence, amount and timing of appropriations for spending on future projects.

Federal highway bills provide spending authorizations that represent maximum amounts. Each year, an appropriation act is passed establishing the amount that can actually be used for particular programs. The annual funding level is generally tied to receipts of highway user taxes placed in the Highway Trust Fund. Once the annual appropriation is passed, funds are distributed to each state based on formulas (“apportionments”) or other procedures (“allocations”). Apportioned and allocated funds generally must be spent on specific programs as outlined in the federal legislation. The Highway Trust Fund has experienced shortfalls in recent years, due to high gas prices, fewer miles driven and improved automobile fuel efficiency. These shortfalls created a significant decline in federal highway funding levels. In response to the projected shortfalls, money has been transferred from the General Fund into the Highway Trust Fund over the past several years. Timely Congressional action is needed to address the funding mechanism for the Highway Trust Fund. We cannot be assured of the existence, timing or amount of federal highway funding levels in the future. We also cannot be assured of the impact of the recent sharp reduction in gasoline prices on the levels of highway user taxes that might be collected in the future and the corresponding levels of funding to the Highway Trust Fund.

At the state level, each state funds its infrastructure spending from specially allocated amounts collected from various taxes, typically gasoline taxes and vehicle fees, along with voter-approved bond programs. Shortages in state tax revenues can reduce the amounts spent on state infrastructure projects, even below amounts awarded under legislative bills. Delays in state infrastructure spending can hurt our business. Many states after the Great Recession experienced state-level funding pressures caused by lower tax revenues or other inability to finance approved projects. For example, North Carolina was among the states that experienced these pressures, and this state disproportionately affects our revenues and profits. Most state budgets, including North Carolina’s, improved in 2014 and later years as increased tax revenues helped resolve budget constraints. North Carolina infrastructure spending recently has been restrained by spending required elsewhere for storm relief and litigation settlements. Despite these restraints, the North Carolina General Assembly has provided interim financial relief for North Carolina to continue to fund its infrastructure spending.

During the past several years, many states have taken on a significantly larger role in funding infrastructure investment, including initiating special-purpose taxes and raising gas taxes. We anticipate further growth in

S-21

state-level funding initiatives, such as bond issues, toll roads and special purpose taxes, as states address infrastructure needs, particularly in periods of federal funding uncertainty. Nevertheless, it is a continuing risk to our business that sufficient funding from federal, state and local sources will not be available to address infrastructure needs.

Our businesses could be impacted by rising interest rates.

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

For example, demand in the residential construction market in which we sell our aggregate products is affected by interest rates. In 2019, the Federal Reserve lowered the federal funds rate to a range of 1.5% to 1.75%, cutting the rate three times during the year. At its December 2019 meeting, the Federal Reserve held the federal funds rate steady and signaled its desire to maintain the rate at that level during 2020. This course of action continued at its January 2020 meeting when the Federal Reserve again held rates steady and changed little in its economic outlook as the United States economy continued to extend its longest expansion on record. On March 3, 2020, the Federal Reserve lowered the federal funds rate by 0.5% to a range of 1.0% to 1.25% due to evolving risks the coronavirus poses to economic activity. There can be no assurance, however, that interest rates will not increase in the future, affecting our business in an adverse manner. The residential construction market accounted for 22% of our aggregates product line shipments in 2019.

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” below.

Increases in our effective income tax rate may harm our results of operations.

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

Any significant increase in our future effective income tax rate could reduce net earnings and free cash flow for future periods.

S-22

Labor disputes could disrupt operations of our businesses.

Labor unions represent approximately 10% of the hourly employees of our Building Materials business and 100% of the hourly employees of our Magnesia Specialties business. Our collective bargaining agreements for employees of our Magnesia Specialties business at the Manistee, Michigan magnesia chemicals plant and the Woodville, Ohio, lime plant expire in August 2023 and June 2022, 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 affect our business.

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

Our business is a capital-intensive business.

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 further 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. We make critical estimates and assumptions involving accounting matters including our goodwill impairment testing, our expenses and cash requirements for our pension plans, our estimated income taxes, and how we account for our property, plant and equipment and inventory. These estimates and assumptions involve matters that are inherently uncertain and require our subjective and complex judgments. If we used different estimates and assumptions or used different ways to determine these estimates, our financial results could differ.

While we believe our estimates and assumptions are appropriate, we could be wrong. Accordingly, our financial results could be different, either higher or lower. We urge you to read the Critical Accounting Policies and Estimates section included under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of our Annual Report on Form 10-K for the year ended December 31, 2019, incorporated by reference herein.

S-23

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

The accounting standards we apply in preparing our financial statements are reviewed by regulatory bodies and are changed from time to time. New or revised accounting standards could, either positively or negatively, affect results reported for periods after adoption of the standards as compared to 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 of our Consolidated financial statements included under Item 8, “Financial Statements and Supplementary Data,” of our Annual Report on Form 10-K for the year ended December 31, 2019, incorporated by reference herein.

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

Disruptions in the credit markets could affect our business.

We have considered the current economic environment and its potential impact to the Company’s business. Demand for aggregates products, particularly in the infrastructure construction market, had been negatively affected by federal and state budget and deficit issues 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 continues to be eroded by economic uncertainty.

A recessionary construction economy can also increase the likelihood we will not be able to collect on all of our accounts receivable with our customers. We are protected in part, however, by payment bonds posted by many of our customers or end-users. Nevertheless, we experienced a delay in payment from some of our customers during the construction downturn, which can 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 doubtful accounts is adequate.

The credit environment could impact the Company’s 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 both newly issued 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 our outstanding variable-rate debt and the interest cost on future borrowings under our credit facilities. While management believes our credit ratings will remain at a composite investment-grade level, we cannot be assured these ratings will remain at those levels. While management believes the Company will continue to have credit available to adequately meet its needs, there can be no assurance of that.

S-24

Our Magnesia Specialties business faces currency risks from its overseas operations.

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. In 2019, the strength of the U.S. dollar in foreign markets negatively affected the overall price of the products of the Magnesia Specialties business when compared to foreign-domiciled competitors.

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 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 one- to two-week scheduled outages at least once a year to refurbish our cement and dolomitic lime production facilities. In 2019, the cement product line incurred shutdown costs of $26.3 million during the year. In 2019, the Magnesia Specialties business incurred shutdown costs of $4.4 million during the year. 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 present additional risks to our business.

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 contacts 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 duration 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 businesses typically generate lower profit margins than our aggregates and cement product lines due to potentially volatile input costs, highly competitive market dynamics and lower barriers to entry. Therefore, if we expand these operations, our consolidated gross margin would likely be adversely affected. Our overall ready mixed concrete and asphalt and paving operations’ gross margin was 10.4% for 2019 and 10.3% for 2018. The overall gross margin of our Building Materials business will continue to be reduced by the lower gross margins for our ready mixed concrete and asphalt and paving product lines.

S-25

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. The financial results of these businesses have been affected by the short supply or high costs of these fuels and energy. Changes in energy costs also affect the prices that the Company pays 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 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. Our last fixed-price commitment for a portion of our diesel fuel requirements expired at the end of 2016.

The average cost per gallon of diesel fuel was $2.08, $2.29 and $1.81 in 2019, 2018 and 2017, respectively. For 2019, the average cost per MCF (thousand cubic feet) for natural gas decreased 4.7% versus 2018, which had decreased approximately 4% from 2017 levels.

The Company’s Magnesia Specialties business has fixed-price agreements for 62% of its 2020 coal, natural gas and petroleum coke needs. The cement operations have fixed-price agreements for a portion of their 2020 coal and natural gas needs.

Cement production requires large amounts of energy, including electricity and fossil fuels. Energy costs represented approximately 22% of the 2019 direct production costs of our cement product line. 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 quite volatile. Price 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, volatility in energy costs can adversely affect the financial results of our cement product line. Profitability of the cement product line is also subject to kiln maintenance, which requires the plant to be shut down for a period of time as repairs are made. The cement product line incurred shutdown costs of $26.3 million and $17.3 million during 2019 and 2018, respectively.

Similarly, our ready mixed concrete and asphalt and paving 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. Liquid asphalt prices were higher in 2019 than in 2018. Liquid asphalt prices may not always follow other energy products (e.g., oil or diesel fuel) because of complexities in the refining process, which converts a barrel of oil into other fuels and petrochemical products.

Cement is sensitive to supply and price volatility.

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.

S-26

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. The 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.

We are dependent on information technology systems and infrastructure, including reliance on third-party vendors and third-party software. Any significant breakdown, invasion, destruction or interruption of these systems by employees, others with authorized access to our systems, or unauthorized persons could negatively impact operations. There is also a risk that we could experience a business interruption, theft of information or reputational damage as a result of a cyber-attack, such as an infiltration of a data center, or data leakage of confidential information either internally or at our third-party providers. While we have invested in the protection of our data and information technology to reduce these risks and routinely test the security of our information systems network, we cannot assure you that our efforts will prevent breakdowns or breaches in our systems that could adversely affect our business.

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 ship 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 rail cars can also affect our ability to transport our products. Rail cars can be used to transport many different types of products across all of our segments. If owners sell or lease rail cars for use in other industries, we may not have enough rail cars 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 product is distributed by barge along rivers in Ohio and West Virginia. We may continue to 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.

S-27

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.

Risks related to the notes

The notes will be subject to prior claims of our secured creditors and the creditors of our subsidiaries, and we may not have sufficient funds to fulfill our obligations under the notes.

The notes will be our unsecured general obligations, ranking equally with our other senior indebtedness and liabilities, and will not be guaranteed by any of our subsidiaries. As a result, the notes will be effectively subordinated to all of our existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally subordinated to all of the existing and future indebtedness and other liabilities (including trade accounts payable) and preferred equity of our subsidiaries. As of December 31, 2019, we had an aggregate amount of approximately $340 million under our secured accounts receivable credit facility on which the borrower is Martin Marietta Funding LLC, a wholly owned subsidiary. Other than the debt outstanding under this facility, our subsidiaries had no indebtedness and the Company’s only other secured indebtedness as of December 31, 2019 was approximately $11 million of finance lease obligations.

The indenture that will govern the notes will permit us and our subsidiaries to incur additional secured debt under specified circumstances. If we incur any secured debt, our assets will be subject to prior claims by our secured creditors. In the event of our bankruptcy, liquidation, reorganization or other winding up, assets that secure our debt will be available to pay obligations on the notes only after all debt secured by those assets has been repaid in full. Holders of the notes will participate in our remaining assets ratably with all of our unsecured and unsubordinated creditors, including the lenders under our revolving credit facility and our trade creditors. This may have the effect of reducing the amount of proceeds paid to you. If there are not sufficient assets remaining to pay all of these creditors, all or a portion of the notes then outstanding would remain unpaid.

The notes will not be guaranteed by any of our subsidiaries and will be structurally subordinated to indebtedness and other liabilities and preferred equity of our subsidiaries. The indenture that will govern the

S-28

notes will not restrict the ability of our subsidiaries to incur indebtedness or other liabilities or issue preferred equity, and any indebtedness and other liabilities (including trade accounts payable) and preferred equity of our subsidiaries will be structurally senior to the notes. In the event of a bankruptcy, liquidation or reorganization of any of our subsidiaries, holders of their indebtedness and their trade and other creditors and holders of their preferred equity will generally be entitled to payment of their claims from the assets of those subsidiaries before any assets of those subsidiaries will be made available for distribution to us.

In the future, certain of our subsidiaries may be required or otherwise designated to guarantee certain indebtedness but not be required to guarantee the notes pursuant to the indenture that will govern the notes. In such circumstance, the notes would be structurally subordinated with respect to the debt and other liabilities of such subsidiaries that do not guarantee the notes but guarantee such indebtedness.

Our indebtedness may impair our financial condition and liquidity and prevent us from fulfilling our obligations under the notes and our other debt instruments.

As of December 31, 2019, we had an aggregate of approximately $2.8 billion of indebtedness outstanding, excluding intercompany liabilities. Of this amount, approximately $340 million was under our secured accounts receivable credit facility on which the borrower is Martin Marietta Funding LLC, a wholly owned subsidiary. Other than the debt outstanding under this facility, our subsidiaries had no indebtedness and the Company’s only other secured indebtedness as of December 31, 2019 was approximately $11 million of finance lease obligations. Our indebtedness could have important consequences to you, including:

Our historical financial results have been, and we anticipate that our future financial results will be, subject to fluctuations. Our ability to generate cash flow from operations is dependent on our ability to execute our business strategy and is also subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. Accordingly, we cannot assure you that our business will generate sufficient cash flow from operations or that future financing will be available to us on attractive terms, or at all, in an amount sufficient to enable us to pay our indebtedness, including the notes, or to fund our other business needs.

The indenture will not limit the amount of indebtedness that we and our subsidiaries may incur.

The indenture that will govern the notes will not limit the amount of indebtedness that we and our subsidiaries may incur. The indenture will not contain any financial maintenance covenants or other provisions that would

S-29

afford the holders of the notes any substantial protection in the event we participate in a highly leveraged or similar transaction. In addition, the indenture will not contain any restrictive covenants prohibiting or otherwise limiting our ability to repurchase common stock, pay dividends or make any payments on junior or other indebtedness. As a result, we may be unable to fulfill our obligations under the notes.

In addition, the limitation on liens covenant contains exceptions for specified “permitted liens” that would allow us and our subsidiaries to borrow substantial additional amounts and to grant liens or security interests with respect to our assets in connection with those borrowings. In light of these exceptions, holders of the notes may be structurally and/or effectively subordinated to new lenders.

The agreements governing our indebtedness contain various covenants that limit our discretion in the operation of our business and also require us to satisfy a financial leverage test and comply with other covenants. The failure to satisfy such test and to comply with such covenants could have a material adverse effect on us.

The agreements governing our indebtedness contain various covenants, subject to exceptions, including covenants that restrict our ability to:

In addition, our existing revolving credit facility requires that we satisfy a leverage ratio test, which is tested as of the last day of each quarter. During periods in which we experience declines in shipments of aggregates products, or otherwise experience the adverse impact of cyclical market trends or other factors, we may not be able to comply with this financial covenant.

Any failure to comply with the restrictions of our existing revolving credit facility or any agreement governing our other indebtedness may result in an event of default under those agreements. Such default may allow the creditors to accelerate the related indebtedness, which acceleration may trigger cross-acceleration or cross-default provisions in other indebtedness. For example, the acceleration of certain indebtedness in excess of $100.0 million would constitute an event of default under our revolving credit facility. Our assets and cash flow may not be sufficient to fully repay borrowings under our outstanding indebtedness, either upon maturity or, if accelerated, upon an event of default.

If, when required, we are unable to repay, refinance or restructure our indebtedness under, or amend the covenants contained in, our existing revolving credit facility, or if a default otherwise occurs, the lenders under our existing revolving credit facility could elect to terminate their commitments thereunder and cease making further loans, and lenders under our existing revolving credit facility could declare all borrowings outstanding, together with accrued interest and other fees, to be immediately due and payable. Any such actions could force us into bankruptcy or liquidation, and we cannot provide any assurance that we could repay our obligations under the notes in such an event.

Changes in our credit ratings may adversely affect the value of the notes.

Agency ratings are not a recommendation to buy, sell or hold any security and may be revised or withdrawn at any time by the issuing organization. We cannot provide assurance as to the credit ratings that may be assigned

S-30

to the notes or that any such credit ratings will remain in effect for any given period of time or that any such ratings will not be lowered (or placed on review for a downgrade), suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances warrant such an action. Further, any such ratings will be limited in scope and will not address all material risks relating to an investment in the notes, but rather will reflect only the view of each rating agency at the time the rating is issued. An explanation of the significance of such rating may be obtained from such rating agency. Any actual or anticipated adverse changes in our credit ratings, including any announcement that our ratings are under further review for a downgrade, could adversely affect the market price of the notes, increase our corporate borrowing costs and limit our access to the capital markets.

Our financial performance and other factors could adversely impact our ability to make payments on the notes.

Our ability to make scheduled payments with respect to our indebtedness, including the notes, will depend on our financial and operating performance, which, in turn, is subject to prevailing economic conditions and to financial, business and other factors beyond our control. We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal of, and premium, if any, and interest on, our indebtedness.

If our cash flows are insufficient to fund our debt service obligations, we could face substantial liquidity problems and may be forced to reduce or delay capital expenditures, sell important assets, seek additional capital or seek to restructure or refinance our indebtedness, including the notes. These alternative measures may not be successful on attractive terms, or at all, and may not permit us to meet our scheduled debt service obligations.

Certain of our borrowings bear interest at floating rates that could rise significantly, increasing our cost and reducing cash flow.

A significant part of our indebtedness, including borrowings under our revolving credit facility, trade receivable facility and floating rate notes, bears interest at per annum rates equal to LIBOR, adjusted periodically, plus a spread. In the past, the LIBOR rate has experienced significant fluctuations. Any historical upward or downward trend in the LIBOR is not an indication that the LIBOR rate is more or less likely to increase or decrease at any time and you should not take historical levels of the LIBOR rate as an indication of its future performance. These interest rates could rise significantly in the future, thereby increasing our interest expenses associated with these obligations, reducing cash flow available for capital expenditures and hindering our ability to make payments on the notes.

We may not be able to repurchase the notes upon a change of control repurchase event.

If a Change of Control Repurchase Event occurs, we will be required to offer to repurchase all of the outstanding notes at a repurchase price equal to 101% of their principal amount, plus unpaid interest, if any, accrued thereon to, but excluding, the date of repurchase, unless we have exercised our right to redeem the notes in full. However, we may not be able to repurchase the notes upon a Change of Control Repurchase Event because we may not have sufficient funds to do so. In addition, agreements governing indebtedness incurred in the future may restrict us from purchasing the notes in the event of a Change of Control Repurchase Event. Any failure to repurchase properly tendered notes would constitute an event of default under the indenture that will govern the notes, which could, in turn, cause an acceleration of our other indebtedness. See “Description of the notes—Change of Control Repurchase Event.”

S-31

The definition of a change of control requiring us to repurchase the notes is limited, and the market price of the notes may decline if we enter into a transaction that is not a change in control under the indenture that will govern the notes.

The term “Change of Control” (as used in the notes and the indenture) is limited in terms of its scope and does not include every event that might cause the market price of the notes to decline. In addition, we are required to repurchase the notes upon a change of control only if the notes receive a reduction in rating below investment grade. Further, the definition of “Change of Control” includes a phrase relating to the transfer of all or substantially all of our assets and those of our subsidiaries, taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder to require us to repurchase the notes as a result of a transfer of less than all of our assets and the assets of our subsidiaries, taken as a whole, to another person or group may be uncertain. Our obligation to repurchase the notes is limited and may not preserve the market price of the notes in the event of a highly leveraged transaction, reorganization, merger or similar transaction. See “Description of the notes—Change of Control Repurchase Event.”

There is no public market for the notes, and we cannot assure you that a market for the notes will develop.

The notes are a new issue of securities with no existing trading market. We do not intend to apply to list the notes on any securities exchange or to arrange for the notes to be quoted on any automated interdealer quotation system. The underwriters have advised us that they currently intend to make a market in the notes, subject to applicable securities laws. However, the underwriters are not obligated to do so and may discontinue any such market-making at any time without notice to, or the consent of, the holders of the notes.

The notes are a new issue of securities for which there is no existing trading market, and no assurance can be given as to:

If a trading market were to exist for the notes, the notes could trade at prices that may be higher or lower than their principal amounts or purchase prices, depending on many factors, including:

An active trading market for the notes may never develop or, even if it develops, may not continue, in which case the trading price of the notes could be adversely affected and your ability to transfer the notes will be limited.

Use of proceeds

We estimate that the net proceeds from this offering will be approximately $489.4 million, after deducting the underwriting discounts and our estimated offering expenses. We intend to use the net proceeds from the notes for general corporate purposes, which will include, among other uses, repayment at maturity of our approximately $300 million aggregate principal amount of floating rate notes due 2020. Our floating rate notes due 2020 are scheduled to mature on May 22, 2020 and bear interest at a rate per annum (reset quarterly) equal to three-month LIBOR for U.S. dollars plus 0.650%.

Pending application of the net proceeds of this offering for the foregoing purposes, we expect to, but we are not required to, invest such net proceeds in either cash or high-quality, short-term debt securities.

Certain underwriters and/or their affiliates may hold a portion of our floating rate notes due 2020. As a result, certain of the underwriters and/or their affiliates may receive a portion of the net proceeds of the offering. See “Underwriting.”

Description of the notes

As used in this section, the “Company” refers only to Martin Marietta Materials, Inc. and not to its consolidated subsidiaries unless the context otherwise requires. The Company will issue $500 million aggregate principal amount of 2.500% Senior Notes due 2030 under an indenture (the “Base Indenture”), dated as of May 22, 2017, between the Company and Regions Bank, as trustee (the “Trustee”), as supplemented by a third supplemental indenture (together with the Base Indenture, the “Indenture”), to be dated as of the closing date of this offering, between the Company and the Trustee. The notes will constitute a separate series of debt securities under the Indenture. The terms of the notes include those expressly set forth in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”).

The following description of selected provisions of the Indenture and the notes is not complete, and is subject to, and qualified in its entirety by reference to, the actual provisions of the Indenture and the notes, including the definitions of certain terms contained therein and those terms made part of the Indenture by reference to the TIA. A copy of the Indenture and forms of notes may be obtained from the Trustee upon request.

General

The initial offering of the notes will be for $500 million in aggregate principal amount and will be issued in fully registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. However, the Company may issue additional debt securities with the same terms as the notes (other than issue date and, to the extent applicable, the date from which interest will begin to accrue and the first payment of interest) and such additional debt securities will be consolidated, and constitute a single series of debt securities, with the notes for all purposes without notice to, or the consent of, the holders of the notes. Unless the context requires otherwise, references to “notes” for all purposes of the Indenture and this “Description of the notes” include any such additional debt securities that are actually issued; provided, however, that in the event such additional debt securities are not fungible with notes for U.S. federal income tax purposes, such additional debt securities will be issued with a separate CUSIP number from the notes. The Company may issue an unlimited principal amount of debt securities under the Indenture.

The notes will be the Company’s senior unsecured obligations, will rank equally in right of payment with all of its existing and future senior indebtedness and will rank senior in right of payment to all of its future subordinated indebtedness. The notes will be effectively subordinated to all of the Company’s existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. The notes will not be guaranteed by any of the Company’s subsidiaries and will be structurally subordinated to all of the existing and future indebtedness and other liabilities (including trade accounts payable) and preferred equity of the Company’s subsidiaries.

Principal and interest

The notes will bear interest from, and including, March 16, 2020 at the rate of 2.500% per annum, based on a 360-day year consisting of twelve 30-day months. Interest on the notes will be payable semiannually in arrears on March 15 and September 15 of each year, commencing September 15, 2020 (each, an “Interest Payment Date”). Interest payments (except defaulted interest, which shall be paid as set forth below) on an Interest Payment Date will be made to the holder in whose name a note is registered at the close of business on the 15th calendar day immediately preceding such Interest Payment Date, whether or not such 15th calendar day is a Business Day (as defined herein) (each, a “Regular Record Date”).

S-36

The Company may, at its option, make payments of interest on an Interest Payment Date by check mailed to the address of each holder entitled to receive such a payment or by wire transfer to an account maintained by each such holder with a bank located in the United States.

Any interest on notes not punctually paid or duly provided for on an applicable Interest Payment Date will forthwith cease to be payable to the holders of such notes on the related Regular Record Date and may either be paid to the persons in whose names such notes are registered at the close of business on a special record date (each, a “Special Record Date”) for the payment of the interest not punctually paid or duly provided for to be fixed by the Company, notice of which shall be mailed to the holders of such notes not less than 15 days prior to such Special Record Date, or may be paid at any time in any other lawful manner, as further described in the Indenture.

The notes will mature on March 15, 2030 (the “Stated Maturity Date”). However, the notes will be redeemable prior to maturity as specified under “—Optional redemption.” If a Change of Control Repurchase Event occurs, the Company will be required to offer to repurchase all of the outstanding notes at a repurchase price equal to 101% of their principal amount plus unpaid interest, if any, accrued thereon to, but excluding, the date of repurchase, unless the Company has exercised its right to redeem the notes in full. See “—Change of Control Repurchase Event.”

The Company will pay the principal of each note on the Stated Maturity Date or the principal of, and premium, if any, and interest, if any, on, each note on any Optional Redemption Date (as defined herein) or any applicable repurchase date (the “Repurchase Date”), as the case may be, by wire transfer of immediately available funds, or in certain limited circumstances, by check.

If any Interest Payment Date, any Stated Maturity Date, any Optional Redemption Date or any Repurchase Date falls on a day that is not a Business Day, the required payment due on such date will instead be made on the next Business Day and no additional interest will accrue with respect to such payment date as a result of payment on such next Business Day. A “Business Day” means any day other than a Saturday, Sunday or other day on which banking institutions in The City of New York or place of payment are authorized or obligated by law, regulation or executive order to close.

Prior to due presentment of a Note for registration of transfer, the Company, the Trustee and any other agent of the Company or the Trustee may treat the registered holder of each note as the owner of such Note for the purpose of receiving payments of principal of, and premium, if any, and interest on, such Note and for all other purposes whatsoever. Subject to certain limitations imposed on global notes, the notes may be surrendered for registration of transfer or exchange thereof in accordance with the terms of the indenture.

The notes will be exchangeable and transferable, at the office or agency of the Company maintained for such purposes, which, initially, will be the corporate trust office of the Trustee located at 1180 West Peachtree St., Suite 1200, Atlanta, GA 30309, Attention: Kristine Prall. No service charge will be made for any registration of transfer, or exchange of notes, except in certain circumstances for any tax or other governmental charge that may be imposed in connection therewith.

Optional redemption

The Company may redeem the notes, at its option, at any time in whole or from time to time in part (equal to a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof), for cash (1) prior to the Par Call Date (as defined herein) at a price equal to the greater of (i) 100% of the principal amount of the notes to be redeemed and (ii) as determined by the Quotation Agent (as defined herein), the sum of the present values of the principal amount of the notes to be redeemed and the remaining scheduled payments of interest thereon

S-37

after the date of optional redemption (an “Optional Redemption Date”) through the Par Call Date (assuming, for this purpose, that the notes are scheduled to mature on the Par Call Date) (the “Assumed Remaining Life”) (excluding interest, if any, accrued thereon to such Optional Redemption Date), discounted to such Optional Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined herein) plus 30 basis points (or 0.300%), and (2) on or after the Par Call Date and prior to maturity, at a price equal to 100% of the principal amount of the notes to be redeemed, plus, in each case, unpaid interest, if any, accrued thereon to, but excluding, such Optional Redemption Date. Notwithstanding the foregoing, the Company will pay any interest installment due on an Interest Payment Date which occurs on or prior to such Optional Redemption Date to the holders of the notes as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the Assumed Remaining Life that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Assumed Remaining Life.

“Comparable Treasury Price” means, with respect to any Optional Redemption Date, the average of two Reference Treasury Dealer Quotations for such Optional Redemption Date.

“Par Call Date” means December 15, 2029, the date that is three months prior to the date that the notes are scheduled to mature.

“Quotation Agent” means, with respect to any Optional Redemption Date, the Reference Treasury Dealer appointed by the Company for such purpose.

“Reference Treasury Dealer” means (i) each of Deutsche Bank Securities Inc. or J.P. Morgan Securities LLC or their respective affiliates that are primary U.S. Government securities dealers and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in The City of New York (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer; and (ii) at the Company’s option, any other Primary Treasury Dealers selected by the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Optional Redemption Date, the average, as determined by the Company, of the bid and asked prices for, as applicable, the Comparable Treasury Issue (expressed as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Optional Redemption Date.

“Treasury Rate” means, with respect to any Optional Redemption Date, the rate per annum equal to the semiannual yield to maturity of the Comparable Treasury Issue, assuming a price for such comparable treasury issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Optional Redemption Date.

Notice of any optional redemption will be mailed at least 15 days but not more than 30 days prior to the Optional Redemption Date to each holder of the notes to be redeemed (with a copy to the Trustee). The notice of redemption will specify, among other items, the aggregate principal amount of the notes to be redeemed, the Optional Redemption Date and a description of the redemption price.

If the Company chooses to redeem less than all of the outstanding notes, then the Company will notify the Trustee at least 30 days before the Optional Redemption Date (or such later date acceptable to the Trustee) of the aggregate principal amount of notes to be redeemed and the Optional Redemption Date. The Trustee will select, pro rata, by lot, or such other manner it deems fair and appropriate, the notes to be redeemed in part. For redemption of global notes in part, see “—Forms.”

S-38

If the Company has provided a proper redemption notice to holders of the notes to be redeemed then, unless the Company defaults in payment of the redemption price, on and after the Optional Redemption Date interest will cease to accrue on such notes.

The Company may at any time, and from time to time, purchase notes at any price or prices in the open market or otherwise.

The notes will not be entitled to the benefit of, or be subject to, any sinking fund obligation.

Change of Control Repurchase Event

If a Change of Control Repurchase Event occurs, the Company will be required to make an irrevocable offer (subject to consummation of the Change of Control Repurchase Event) to each holder of notes to repurchase all or, at the election of such holder, any part (equal to a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof) of such holder’s notes for cash at a price equal to 101% of the principal amount of such notes to be repurchased plus unpaid interest, if any, accrued thereon to, but excluding, the Repurchase Date, unless the Company has exercised its right to redeem the notes in full. Notwithstanding the foregoing, the Company will pay any interest installment due on an Interest Payment Date which occurs on or prior to the Repurchase Date to the holders of the notes as of the close of business on the applicable Regular Record Date immediately preceding such Interest Payment Date.

Within 30 days following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control (as defined herein), but after the public announcement of the Change of Control, the Company will mail a notice to each holder of notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase all of such notes on the Repurchase Date specified in the notice, which date will, subject to the following sentence, be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to repurchase such notes is conditioned on the Change of Control Repurchase Event occurring on or prior to the Repurchase Date specified in the notice.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of the notes by virtue of such conflict.

On the Repurchase Date, the Company will, to the extent lawful:

S-39

The Paying Agent will promptly mail to each holder of notes properly tendered the repurchase price for such notes, and the Trustee, upon the Company’s execution and delivery of the related notes, will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new note of the same series equal in principal amount to any unrepurchased portion of any notes properly tendered.

The Company will not be required to make an offer to repurchase the notes upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer to be made by the Company and such third party purchases all notes properly tendered and not withdrawn by the holders thereof under its offer.

The definition of “Change of Control” includes a phrase relating to the sale, lease, exchange or other transfer of all or substantially all of the assets of the Company and its Subsidiaries (as defined herein), taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder to require the Company to repurchase the notes as a result of a sale, lease, exchange or other transfer of less than all of the assets of the Company and its Subsidiaries, taken as a whole, to another person or group may be uncertain.

“Below Investment Grade Rating Event” means the rating on the notes is lowered by at least two of the three Rating Agencies (as defined herein) and the notes are rated below an Investment Grade Rating (as defined herein) by at least two of the three Rating Agencies on any day during the period (which period shall be extended so long as the rating of the notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) commencing 60 days prior to the first public notice of the earlier of the Company’s intention to effect a Change of Control and the occurrence of a Change of Control and ending 60 days following consummation of such Change of Control.

“Change of Control” means (1) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any person or group (as used in Section 13(d)(3) of the Exchange Act) becomes the beneficial owner, directly or indirectly, of more than 50% of the Company’s Voting Stock (as defined herein), measured by voting power rather than number of shares, (2) any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to any person or group of related persons for the purpose of Section 13(d)(3) of the Exchange Act, together with any affiliates thereof, other than any such sale, lease, exchange or other transfer to one or more of the Company’s Subsidiaries (whether or not otherwise in compliance with the provisions of the Indenture) or (3) the adoption of a plan relating to the liquidation, dissolution or winding up of the Company.

Notwithstanding the foregoing, a transaction effected to create a holding company for the Company will not be deemed to involve a Change of Control if (a) pursuant to such transaction the Company becomes a wholly owned subsidiary of such holding company and (b) the holders of the outstanding Voting Stock of such holding company immediately following such transaction are the same as the holders of the Company’s outstanding Voting Stock immediately prior to such transaction.

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Fitch” means Fitch Inc. and its successors.

“Investment Grade Rating” means a rating equal to or higher than Baa3 (or the equivalent under any successor rating categories) by Moody’s (as defined herein), BBB- (or the equivalent under any successor rating categories) by S&P (as defined herein) and BBB- (or the equivalent under any successor rating categories) by Fitch and the equivalent investment grade credit rating from any replacement rating agency or rating agencies selected by the Company.

S-40

“Moody’s” means Moody’s Investors Service Inc. and its successors.

“Rating Agency” means (1) each of Moody’s, S&P and Fitch and (2) if any of Moody’s, S&P or Fitch ceases to rate the notes or fails to make a rating publicly available for reasons outside the control of the Company, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) under the Exchange Act selected by the Company (as certified by a resolution of the Company’s board of directors) to act as a replacement agency for Moody’s, S&P or Fitch, or all of them, as the case may be.

“S&P” means S&P Global Ratings, a business unit of Standard & Poor’s Financial Services LLC, and its successors.

“Subsidiary” means an entity a majority of the Voting Stock of which is owned by the Company and/or one or more other entities a majority of the Voting Stock of which is owned by the Company.

“Voting Stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date means the capital stock or other ownership interests of such person that is at the time entitled to vote generally in the election of the board of directors (or members of a comparable governing body) of such person.

Forms

The notes will be issued in the form of one or more registered notes in global form, without interest coupons. Such global notes will be deposited on the issue date with DTC and registered in the name of Cede & Co., as nominee of DTC, or will remain in the custody of the Trustee under the Indenture. Beneficial interests in the global notes may not be exchanged for certificated notes except in the circumstances described below. All interests in global notes may be subject to the procedures and requirements of DTC.

Exchanges of beneficial interests in one global security for interests in another global security will be subject to the applicable rules and procedures of DTC and its direct and indirect participants. Any beneficial interest in one of the global notes that is transferred to a person who takes delivery in the form of an interest in another global security will, upon transfer, cease to be an interest in that global security and become an interest in the global security to which the beneficial interest is transferred and, accordingly, will thereafter be subject to all procedures applicable to beneficial interests in the global security to which the beneficial interest is transferred for as long as it remains an interest in that global security.

The descriptions of the operations and procedures of DTC set forth below are based on materials made available by DTC. These operations and procedures are solely within the control of the respective settlement systems and are subject to change by them from time to time. We do not take any responsibility for these operations or procedures, and investors are urged to contact the relevant system or its participants directly to discuss these matters. The information set forth below has been obtained from sources that the Company believes to be reliable, but neither the Company nor the underwriters take any responsibility for the accuracy of such information. Furthermore, neither the Company nor the underwriters will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, interests in any global notes held through the facilities of any clearing system or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

DTC has advised us that it is a limited purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities for persons who have accounts with DTC (“participants”) and facilitates the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, which

S-41

eliminates the need for physical movement of certificates. Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Indirect access to the DTC system is available to others such as securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a direct or indirect custodial relationship with a participant (“indirect participants”). Investors who are not participants may beneficially own notes held by or on behalf of DTC only through participants or indirect participants. The rules applicable to DTC and its participants are on file with the SEC.

Upon the issuance of a global note, DTC or its custodian will credit, on its internal system, the respective principal amount of the individual beneficial interests represented by the global note to the accounts of the persons who have accounts with DTC. Such accounts initially will be designated by or on behalf of the underwriters. Ownership of beneficial interests in the global note will be limited to participants or persons who hold interests through participants. Ownership of beneficial interests in the global note will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants and indirect participants (with respect to interests of persons other than participants).

So long as DTC or its nominee is the registered owner or holder of a global note, DTC or such nominee, as the case may be, will be considered the sole record owner or holder of the notes represented by such global note for all purposes under the Indenture and the notes. Except as set forth herein, owners of beneficial interests in a global note will not be entitled to have notes represented by such global note registered in their names, will not receive or be entitled to receive physical delivery of notes in definitive certificated form, and will not be considered holders of the notes for any purposes under the Indenture.

Accordingly, each person owning a beneficial interest in a global note must rely on the procedures of DTC and, if such person is not a participant, on the procedures of the participant through which such person directly or indirectly owns its interest, to exercise any rights of a holder under the Indenture. We understand that under existing industry practices, if we request any action of holders or any owner of a beneficial interest in a global note desires to give any notice or take any action that a holder is entitled to give or take under the Indenture, DTC would authorize the participants holding the relevant beneficial interests to give such notice or take such action, and such participants would authorize beneficial owners owning through such participants to give such notice or take such action or would otherwise act upon the instructions of beneficial owners owning through them.

Payments of the principal of, premium, if any, and interest on a global note will be made to DTC or its nominee, as the case may be, as the registered owner. Neither we, the Trustee nor any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

We expect that DTC or its nominee, upon receipt of any payment of principal of, premium, if any, or interest in respect of a global note will credit participants’ accounts with payments in amounts proportionate to their respective beneficial ownership interests in the principal amount of such global note, as shown on the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in a global note held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. The participants will be responsible for such payments.

The Indenture will provide that, if the Depository notifies us that it is unwilling or unable to continue as depository for the global notes or if at any time the Depository ceases to be a clearing agency registered under

S-42

the Exchange Act and we do not appoint a successor depository within 90 days, or if there shall have occurred and be continuing an Event of Default or an event which, with the giving of notice or lapse of time, or both, would constitute an Event of Default with respect to the notes and a request for such exchange is made by DTC, then we will issue certificated notes in exchange for the global note. In addition, we may at any time and in our sole discretion determine not to have the notes represented by a global note and, in such event, will issue certificated notes in exchange for the global note. In any such instance, an owner of a beneficial interest in a global note will be entitled to physical delivery of certificated notes equal in principal amount to its beneficial interest and to have the certificated notes registered in its name. We expect that instructions for registering the certificated notes would be based upon directions received from the Depository with respect to ownership of the beneficial interests in a global note.

Although DTC has agreed to the procedures described above in order to facilitate transfers of interests in a global note among participants of DTC, it is under no obligation to perform such procedures and such procedures may be discontinued at any time. Neither we nor the Trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Amendment, supplement and waiver

Subject to certain exceptions, the Indenture and the notes may be amended or supplemented with the consent of the holders of a majority in principal amount of all the then outstanding securities issued pursuant to the Indenture (including any additional securities of a series issued pursuant to the Indenture after the date of the issuance of the notes offered hereby), voting as a single class; provided that (i) if any such amendment or supplement would by its terms disproportionately and adversely affect a series of securities issued under the Indenture, such amendment or supplement shall also require the consent of the holders of a majority in principal amount of the then outstanding securities of such series and (ii) if any such amendment or supplement would only affect the securities of some but not all series of securities issued under the Indenture, then only the consent of the holders of a majority in principal amount of the then outstanding securities of all such affected series of securities issued under the Indenture (and not the consent of a majority in principal amount of all the then outstanding securities issued under the Indenture) shall be required; and provided, further, that the Company and the Trustee may not, without the consent of the holder of each outstanding security of a series affected thereby:

Any past default or compliance with any provisions of the Indenture or the securities issued thereunder may be waived with the consent of the holders of a majority in principal amount of all the then outstanding securities issued pursuant to the Indenture (including any additional securities of a series issued pursuant to the Indenture after the date of the issuance of the notes offered hereby), voting as a single class; provided that (i) if any such waiver would by its terms disproportionately and adversely affect a series of securities under the

S-43

Indenture, such waiver shall also require the consent of the holders of a majority in principal amount of the then outstanding securities of such series and (ii) if any such waiver would only affect some but not all series of securities issued under the Indenture, then only the consent of the holders of a majority in principal amount of the then outstanding securities of such affected series issued under the Indenture (and not the consent of a majority in principal amount of all the then outstanding securities issued under the Indenture) shall be required; and provided, further, that no waiver shall be effective without the consent of the holder of each outstanding security affected thereby in the case of a default in any payment of principal, premium, if any, or interest due in respect of any security or in respect of other provisions which under the Indenture cannot be modified or amended without the consent of the holder of each outstanding security affected.

Without notice to or the consent of any holder of notes, the Company and the Trustee may amend or supplement the Indenture or the notes to:

Whenever the Company requests the Trustee to take any action under the Indenture, including a request to amend or supplement the Indenture, the Company is required to furnish the Trustee with an officers’ certificate and an opinion of counsel to the effect that all conditions precedent to the action have been complied with.

Covenants

The terms of the notes and the covenants contained in the Indenture do not afford holders of the notes protection in the event of a highly leveraged or other similar transaction involving the Company that may adversely affect holders of the notes. The Indenture will not limit the amount of additional unsecured indebtedness that the Company or any of its Subsidiaries may incur.

Limitations on liens

Subject to the following three sentences, the Company will not, and will not permit any Restricted Subsidiary (as defined herein) to, as security for any Debt (as defined herein), incur a Lien (as defined herein) on any Restricted

S-44

Property (as defined herein), unless the Company or such Restricted Subsidiary secures or causes to be secured any outstanding notes equally and ratably with all Debt secured by such Lien. The Lien may equally and ratably secure such notes and any other obligations of the Company or its Subsidiaries that are not subordinated in right of payment to any outstanding notes. The foregoing restriction will not apply to, among other things, Liens:

In addition and notwithstanding the foregoing restrictions, the Company and any of its Restricted Subsidiaries may, without securing the notes, incur a Lien that otherwise would be subject to the foregoing restrictions; provided that after giving effect to such Lien the aggregate amount of all Debt secured by Liens that otherwise would be prohibited (for the avoidance of doubt, excluding Debt secured by a Lien permitted by any of clauses (1) through (6) above) plus all Attributable Debt (as defined herein) in respect of sale-leaseback transactions that otherwise would be prohibited by the covenant limiting sale-leaseback transactions described below at the time such Lien is incurred would not exceed 15% of Consolidated Net Tangible Assets (as defined herein).

Limitations on sale-leaseback transactions

Subject to the following two sentences, the Company will not, and will not permit any Restricted Subsidiary to, sell or transfer a Principal Property (as defined herein) and contemporaneously lease it back, except a lease for a period of three years or less. Notwithstanding the foregoing restriction, the Company or any Restricted Subsidiary may sell or transfer a Principal Property and contemporaneously lease it back for a longer period if:

S-45

In addition and notwithstanding the foregoing restrictions, the Company and any of its Restricted Subsidiaries may, without securing the notes, enter into a sale-leaseback transaction that otherwise would be subject to the foregoing restrictions; provided that after giving effect to such sale-leaseback transaction the aggregate amount of all Debt secured by Liens that otherwise would be prohibited by the covenant limiting Liens described above plus (for the avoidance of doubt, excluding Debt secured by a Lien permitted by any of clauses (1) through (6) thereof) all Attributable Debt in respect of sale-leaseback transactions that otherwise would be prohibited above would not exceed 15% of Consolidated Net Tangible Assets.

Consolidation, merger, sale of assets

The Company shall not consolidate with or merge into, or transfer all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to, another entity unless:

If, upon any such consolidation, merger or transfer, a Restricted Property would become subject to an attaching Lien that secures Debt, then, before the consolidation, merger or transfer occurs, the Company by supplemental indenture shall secure the notes by a direct lien on such Restricted Property. The direct Lien shall have priority over all Liens on such Restricted Property except those already on it. The direct Lien may equally and ratably secure the notes and any other obligation of the Company or a Subsidiary. However, the Company need not comply with this provision if (i) upon the consolidation, merger or transfer, the attaching Lien will secure the notes equally and ratably with or prior to Debt secured by the attaching Lien or (ii) the Company or a Restricted Subsidiary could create a Lien on the Restricted Property to secure Debt at least equal in amount to that secured by the attaching Lien pursuant to the provisions described under “—Limitations on liens” above.

S-46

When a successor entity assumes all of the obligations of the Company under the notes and the Indenture and the other conditions specified above are satisfied, the Company will be released from those obligations.

Definitions

For purposes of the covenants included in the Indenture, the following terms generally shall have the meanings provided below.

“Attributable Debt” for a lease means the carrying value of the capitalized rental obligation determined under generally accepted accounting principles whether or not such obligation is required to be shown on the balance sheet as a long-term liability. The carrying value may be reduced by the capitalized value of the rental obligations, calculated on the same basis, that any sublessee has for all or part of the same property. A lease obligation shall be counted only once even if the Company and one or more of its Subsidiaries may be responsible for the obligation.

“Capital Expenditures” means, for any period, any expenditures of the Company or its Subsidiaries during such period that, in conformity with U.S. generally accepted accounting principles consistently applied, are required to be included in fixed asset accounts as reflected in the consolidated balance sheet of the Company and its Subsidiaries.

“Consolidated Net Tangible Assets” means, as of any date of determination, total assets less:

“Debt” means any debt for borrowed money which would appear, in conformity with generally accepted accounting principles, on the balance sheet as a liability or any guarantee of such a debt and includes purchase money obligations. A Debt shall be counted only once even if the Company and one or more of its Subsidiaries may be responsible for the obligation.

“Lien” means any mortgage, pledge, security interest or lien.

“Long-Term Debt” means Debt that by its terms matures on a date more than 12 months after the date it was created or Debt that the obligor may extend or renew without the obligee’s consent to a date more than 12 months after the Debt was created.

“Principal Property” means any mining and quarrying or manufacturing facility located in the United States and owned by the Company or by one or more Restricted Subsidiaries on the date the notes are first issued and which has, as of the date the Lien is incurred, a net book value (after deduction of depreciation and other similar charges) greater than 3% of Consolidated Net Tangible Assets, except:

S-47

“Restricted Property” means any Principal Property, any Debt of a Restricted Subsidiary owned by the Company or a Restricted Subsidiary on the date the notes are first issued or thereafter if secured by a Principal Property (including any property received upon a conversion or exchange of such debt), or any shares of stock of a Restricted Subsidiary owned by the Company or a Restricted Subsidiary (including any property or shares received upon a conversion, stock split or other distribution with respect to the ownership of such stock).

“Restricted Subsidiary” means a Subsidiary that has substantially all of its assets located in, or carries on substantially all of its business in, the United States and that owns a Principal Property. Notwithstanding the preceding sentence, a Subsidiary shall not be a Restricted Subsidiary during such period of time as it has shares of capital stock registered under the Exchange Act or it files reports and other information with the SEC pursuant to Section 13 or 15(d) of the Exchange Act.

Default and remedies

An “Event of Default” under the Indenture in respect of the notes is:

If an Event of Default in respect of the notes (other than as referred to in clause (4) above) occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the then outstanding notes may declare the notes to be due and payable immediately. Under certain conditions, such acceleration may be rescinded by the holders of a majority in principal amount of the then outstanding notes if such rescission would not conflict with any judgment or decree, except with respect to nonpayment of principal or premium (if any) or interest on the notes. If an Event of Default referred to in clause (4) above occurs and is continuing, the principal of, and premium, if any, and interest on, all of the then outstanding notes will become immediately due and payable without any declaration or other act on the part of the Trustee or the holders of the notes.

No holder of notes may pursue any remedy against the Company under the Indenture (other than with respect to the right to receive any payment of principal, premium, if any, or interest due in respect of the notes) unless such holder previously shall have given to the Trustee written notice of default and unless the holders of at least 25% in principal amount of the then outstanding notes shall have made written request to the Trustee to pursue the remedy and shall have offered the Trustee indemnity satisfactory to it, the Trustee shall not have complied with the request within 60 days of receipt of the request and the offer of indemnity, and the Trustee shall not have received direction inconsistent with the request during such 60-day period from the holders of a majority in principal amount of the then outstanding notes.

Holders of the notes may not enforce the Indenture or the notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the notes unless it receives indemnity satisfactory to it from the Company or, under certain circumstances, the holders of such notes seeking to direct the Trustee to take certain actions under the Indenture against any loss, liability or expense.

S-48

Subject to certain limitations, holders of a majority in principal amount of the then outstanding notes may direct the Trustee in its exercise of any trust or power under the Indenture in respect of the notes. The

Indenture provides that the Trustee will give to the holders of the notes notice of all defaults known to it, within 90 days after the occurrence of any default with respect to the notes, unless the default shall have been cured or waived. The Trustee may withhold from holders of the notes notice of any continuing default (except a default in any payment of principal, premium, if any, or interest due in respect of the notes) if it determines in good faith that withholding such notice is in the interests of such holders. The Company is required annually to certify to the Trustee as to the compliance by the Company with certain covenants under the Indenture and the absence of a default thereunder, or as to any such default that existed.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. By accepting a Note, the holder of such Note waives and releases all such claims and liability. This waiver and release are part of the consideration for the issue of such Note.

Discharge, defeasance and covenant defeasance

Satisfaction and discharge

Upon the Company’s direction, the Indenture shall cease to be of further effect with respect to the notes, subject to the survival of specified provisions of the Indenture, when:

Defeasance and covenant defeasance

The Company may elect with respect to the notes either:

S-49

in either case, upon the irrevocable deposit with the Trustee, or other qualifying Trustee, in trust for that purpose, of an amount in U.S. dollars or U.S. government obligations (or a combination thereof) that through the payment of principal and interest in accordance with their terms will provide money, in an amount sufficient to pay the principal of, and premium, if any, and interest on, those notes, on the respective due dates for those payments, whether at maturity, upon redemption or repurchase or otherwise.

The full defeasance or covenant defeasance described above shall only be effective if, among other things:

in either case, to the effect that, and based on such ruling or change the opinion of counsel shall confirm that, the holders of the notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the full defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the defeasance had not occurred;

S-50

Notwithstanding the foregoing, the opinion of counsel required by clause (b) above with respect to a full defeasance need not to be delivered if all notes not therefore delivered to the Trustee for cancellation (x) have become due and payable or (y) will become due and payable at stated maturity within one year under arrangements reasonably satisfactory to the Trustee for the giving of notice of optional redemption by the Trustee in the name, and at the expense, of the Company.

In the event the Company effects covenant defeasance with respect to the notes and those notes are declared due and payable because of the occurrence of any Event of Default other than an Event of Default with respect to the covenant as to which covenant defeasance has been effected, which covenant would no longer be applicable to those notes after covenant defeasance, the amount of monies or U.S. government obligations deposited with the Trustee to effect covenant defeasance may not be sufficient to pay amounts due on those notes at the time of any acceleration resulting from such Event of Default. However, the Company would remain liable to make payment of those amounts due at the time of acceleration.

Repayment of unclaimed funds

The Indenture provides that the Trustee and the Paying Agent shall promptly pay to the Company upon request any money held by them for the payment of principal of, or premium, if any, or interest on, the notes that remains unclaimed for two years. In the event the Trustee or the Paying Agent returns money to the Company following such two-year period, the holders of the notes thereafter shall be entitled to payment only from the Company, subject to all applicable escheat, abandoned property and similar laws.

Concerning the Trustee

Regions Bank is the Trustee, Paying Agent and Registrar under the Indenture. Regions Bank also performs other services for the Company in the normal course of business.

The Indenture provides that there may be more than one Trustee under the Indenture, each with respect to one series of notes. If there are different Trustees for different series of notes, each Trustee will be a Trustee separate and apart from any other Trustee under the Indenture. Any action permitted to be taken by a Trustee may be taken by such Trustee only with respect to the series of notes for which it is the Trustee under the Indenture. Any Trustee under the Indenture may resign or be removed with respect to one or more series of notes.

All payments of principal of, and premium, if any, and interest on, and all registration, transfer, exchange, authentication and delivery (including authentication and delivery on original issuance of the debt securities) of, the notes will be made in an office or agency maintained by the Company for that purpose in the United States, except as otherwise specified above under “—Principal and interest.”

The Company shall be responsible for making all calculations and determinations called for under the Indenture. These calculations and determinations include, but are not limited to, accrued interest payable on the notes, and any premium payable in connection with an optional redemption. The Company shall make all these calculations in good faith and, absent manifest error, the Company’s calculations shall be final and binding on holders of notes. Upon written request, the Company shall provide a schedule of its calculations to the Trustee. The Trustee is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification.

Governing law

The Indenture and the notes will be governed by, and construed in accordance with, the laws of the State of New York.

S-51

Material U.S. federal income tax considerations

The following discussion is a summary of material U.S. federal income tax consequences of the purchase, ownership and disposition of the notes, but does not purport to be a complete analysis of all potential tax effects. The summary does not address the effects of any U.S. federal tax laws other than U.S. federal income tax laws (such as estate and gift tax laws) or any state, local or non-U.S. tax laws. This discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations issued thereunder, and judicial and administrative interpretations thereof, each as in effect on the date hereof, and all of which are subject to change. Any such change may be applied retroactively in a manner that could adversely affect a holder of the notes.

This discussion does not address all of the U.S. federal income tax consequences that may be relevant to a holder in light of such holder’s particular circumstances, including the impact of the unearned income Medicare contribution tax, or to holders subject to special rules, such as certain financial institutions, U.S. expatriates, insurance companies, dealers in securities or currencies, traders in securities, U.S. Holders (as defined below) whose functional currency is not the U.S. dollar, tax-exempt entities, regulated investment companies, real estate investment trusts, partnerships or other pass-through entities and investors in such entities, persons liable for alternative minimum tax, U.S. Holders that hold notes through non-U.S. brokers or other non-U.S. intermediaries and persons holding the notes as part of a “straddle,” “hedge,” “conversion transaction” or other integrated transaction. In addition, this discussion is limited to persons who purchase the notes for cash at original issue and at their “issue price” (i.e., the first price at which a substantial amount of the notes is sold to the public for cash, excluding to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) and who hold the notes as capital assets within the meaning of Section 1221 of the Code.

If any entity treated as a partnership for U.S. federal income tax purposes holds the notes, the U.S. tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. Partnerships considering investments in the notes, and partners in such partnerships, should consult their tax advisors regarding the U.S. federal income tax consequences of the purchase, ownership and disposition of the notes.

Prospective purchasers of the notes should consult their tax advisors concerning the tax consequences of holding notes in light of their particular circumstances, including the application of the U.S. federal income tax considerations discussed below, as well as the application of other federal, state, local, foreign or other tax laws.

Additional payments

Under certain circumstances (see “Description of the notes—Change of Control Repurchase Event”), we may become obligated to make payments on the notes in excess of stated principal and interest. Treasury regulations provide special rules for contingent payment debt instruments which, if applicable, could cause the timing, amount and character of a holder’s income, gain or loss with respect to the notes to be different from the consequences described below. Under the applicable Treasury regulations, however, for purposes of determining whether a debt instrument is a contingent payment debt instrument, remote or incidental contingencies (determined as of the date the notes are issued) are ignored. We believe the possibility of making additional payments on the notes is remote and/or incidental. Therefore, we intend to treat the possibility of the payment of such additional amounts as not resulting in the notes being treated as contingent payment debt instruments under the applicable Treasury regulations. Our treatment will be binding on all holders for U.S. federal income tax purposes unless they disclose their contrary positions to the U.S. Internal Revenue Service

S-52

(“IRS”) in the manner required by applicable U.S. Treasury regulations. Our treatment is not binding on the IRS, however, which may take a contrary position and treat the notes as contingent payment debt instruments. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments.

Tax consequences to U.S. Holders

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of a note that is, for U.S. federal income tax purposes (i) an individual who is a citizen or resident of the United States; (ii) a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or of any political subdivision thereof; (iii) any estate, the income of which is subject to U.S. federal income taxation regardless of its source; or (iv) any trust, if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or if a valid election is in place to treat the trust as a U.S. person.

Payments of stated interest

Payments of stated interest on the notes generally will be taxable to a U.S. Holder as ordinary income at the time that such payments are received or accrued, in accordance with such U.S. Holder’s regular method of accounting for U.S. federal income tax purposes.

Sale, redemption or other taxable disposition of the notes

Upon the sale, redemption or other taxable disposition of a note, a U.S. Holder generally will recognize gain or loss equal to the difference, if any, between the amount realized upon such disposition (less an amount equal to any accrued but unpaid stated interest, which will be taxable as stated interest income as discussed above to the extent not previously included in income by the U.S. Holder) and such U.S. Holder’s adjusted tax basis in the note. A U.S. Holder’s adjusted tax basis in a note will, in general, be the cost of such note to such U.S. Holder.

Gain or loss realized on the sale, redemption or other taxable disposition of a note will generally be capital gain or loss. Capital gains of non-corporate U.S. Holders (including individuals) derived in respect of capital assets held for more than one year are generally eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Backup withholding and information reporting

In general, information reporting requirements will apply to payments of stated interest on the notes and to the proceeds of the sale or other disposition (including a retirement or redemption) of a note paid to a U.S. Holder unless such U.S. Holder is an exempt recipient, and, when required, provides evidence of such exemption. Backup withholding may apply to such payments if the U.S. Holder fails to provide a taxpayer identification number or a certification that it is not subject to backup withholding.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Tax consequences to Non-U.S. Holders

As used herein, the term “Non-U.S. Holder” means a beneficial owner of a note (other than an entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not a U.S. Holder.

S-53

Payments of stated interest

Subject to the discussions below regarding effectively connected income, backup withholding and FATCA (as defined below), interest paid on a note to a Non-U.S. Holder generally will not be subject to U.S. federal withholding tax; provided that:

Even if a Non-U.S. Holder meets the above requirements, interest paid to such Non-U.S. Holder will be subject to U.S. federal withholding tax if the withholding agent knows or has reason to know that the Non-U.S. Holder is not entitled to an exemption.

Payments of interest made to a Non-U.S. Holder that do not satisfy the conditions described above and that are not effectively connected with a U.S. trade or business will generally be subject to U.S. withholding tax at a rate of 30%, unless an income tax treaty applies to reduce or eliminate withholding and the Non-U.S. Holder provides us with a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E (or applicable successor form) claiming the exemption.

If interest on a note is effectively connected with the conduct by a Non-U.S. Holder of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States), the Non-U.S. Holder, although exempt from the withholding tax discussed in the preceding paragraph, will generally be taxed in the same manner as a U.S. Holder (see “—Tax consequences to U.S. Holders” above), provided that the holder provides a properly executed IRS Form W-8ECI in order to claim an exemption from withholding tax. These holders should consult their own tax advisors with respect to other U.S. tax consequences of the ownership and disposition of notes, including the possible imposition of a branch profits tax at a rate of 30% (or a lower treaty rate).

Sale, redemption or other taxable disposition of the notes

Subject to the discussion below regarding backup withholding and FATCA, a Non-U.S. Holder of a note generally will not be subject to U.S. federal income tax on gain realized on the sale, redemption or other disposition of such note unless (i) the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States) or (ii) the Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year of the disposition and certain other conditions are met. These rules are complex, and such Non-U.S. Holders are urged to consult their own tax advisors regarding the potential application of these rules to their situation.

If gain realized on a sale, redemption or other disposition of a note is effectively connected with a Non-U.S. Holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United

S-54

States), the Non-U.S. Holder will generally be taxed in the same manner as a U.S. Holder (see “—Tax consequences to U.S. Holders” above). These holders should consult their own tax advisors with respect to other U.S. tax consequences of the ownership and disposition of notes, including the possible imposition of a branch profits tax at a rate of 30% (or a lower treaty rate).

Backup withholding and information reporting

Unless certain exceptions apply, we must report to the IRS any payments of interest to a Non-U.S. Holder during the taxable year and the amount of tax, if any, withheld with respect to those payments. Copies of the information returns reporting such interest payments and any withholding tax may also be made available to the tax authorities in the country in which such holder resides under the provisions of an applicable income tax treaty. Under current U.S. federal income tax law, backup withholding tax will not apply to payments of interest by us or our paying agent on a note to a Non-U.S. Holder if such holder provides us with a properly completed IRS Form W-8BEN or IRS Form W-8BEN-E, provided that we do not, or our paying agent does not, as the case may be, know or have reason to know that such holder is a U.S. person.

Payments pursuant to the sale or other disposition of notes, made to or through a foreign office of a foreign broker, other than payments in respect of interest, generally will not be subject to information reporting and backup withholding. However, information reporting and, depending on the circumstances, backup withholding may apply if the foreign broker has certain connections to the United States, unless the beneficial owner of the note certifies, under penalties of perjury, that it is not a U.S. person (and we do not, or our paying agent does not, as the case may be, know or have reason to know that such holder is a U.S. person), or otherwise establishes an exemption. Payments to or through a U.S. broker or a U.S. office of a foreign broker, however, generally are subject to information reporting and backup withholding, unless the beneficial owner of the notes certifies, under penalties of perjury, that it is not a U.S. person (and we do not, or our paying agent does not, as the case may be, know or have reason to know that such holder is a U.S. person), or otherwise establishes an exemption.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability; provided the required information is timely furnished to the IRS.

FATCA

Sections 1471 through 1474 of the Code (provisions commonly known as “FATCA”) generally may impose U.S. federal withholding tax of 30% on payments of interest paid to (i) a “foreign financial institution” (as specifically defined in section 1471 of the Code) whether such foreign financial institution is the beneficial owner or an intermediary, unless such foreign financial institution agrees to verify, report and disclose its “United States account” holders (as specifically defined in section 1471 of the Code) and meets certain other specified requirements or (ii) a non-financial foreign entity, whether such non-financial foreign entity is the beneficial owner or an intermediary, unless such entity provides a certification that the beneficial owner of the payment does not have any substantial U.S. owners or provides the name, address and taxpayer identification number of each such substantial U.S. owner and certain other specified requirements are met. In certain cases, the relevant foreign financial institution or non-financial foreign entity may qualify for an exemption from, or be deemed to be in compliance with, these rules. In the event any withholding under FATCA is required or advisable with respect to any payments on the notes, there will be no additional amounts payable to compensate for the withheld amount. If an interest payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under “—Tax consequences to Non-U.S. Holders— Payments of stated interest,” the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. Holders should consult their own tax advisors regarding the possible implications of FATCA on their investments in the notes.

S-55

Material ERISA considerations

The following is a summary of material considerations associated with the purchase of the notes by employee benefit plans that are subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”); plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Code or provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of the Code or ERISA (collectively, “Similar Laws”); and entities whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”).

General fiduciary matters

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”) and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of such an ERISA Plan or the management or disposition of the assets of such an ERISA Plan, or who renders investment advice for a fee or other compensation to such an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

In considering an investment in the notes of a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws. In addition, a fiduciary of a Plan should consult with its counsel in order to determine if the investment satisfies the fiduciary’s duties to the Plan, including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws.

Prohibited transaction issues

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is available. A party in interest or disqualified person who engaged in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engaged in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code. The acquisition and/or holding of notes by an ERISA Plan with respect to which the Issuer, the underwriters or any guarantor is considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption.

The U.S. Department of Labor has issued prohibited transaction class exemptions that may apply to the tendering of the notes. These exemptions include transactions effected on behalf of an ERISA Plan by a “qualified professional asset manager” (prohibited transaction exemption 84-14) or an “in-house asset manager” (prohibited transaction exemption 96-23), transactions involving insurance company general accounts (prohibited transaction exemption 95-60), transactions involving insurance company pooled separate accounts (prohibited transaction exemption 90-1), and transactions involving bank collective investment funds (prohibited transaction exemption 91-38). In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide relief from the

S-56

prohibited transaction provisions of ERISA and Section 4975 of the Code for certain transactions, provided that neither the issuer of the securities nor any of its affiliates (directly or indirectly) have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any Plan involved in the transaction and provided further that the Plan receives no less and pays no more than “adequate consideration” (within the meaning of Section 408(b)(17) of ERISA and Section 4975(f)(10) of the Code). Each of these exemptions contains conditions and limitations on its application, and there can be no assurance that all of the conditions will be satisfied. Therefore, each person that is considering acquiring or holding the notes in reliance on an exemption should carefully review and consult with its legal advisors to confirm that it is applicable to the purchase and holding of the notes.

In light of the above, the notes should not be purchased or held by any person investing “plan assets” of any Plan, unless such purchase and holding will not constitute a nonexempt prohibited transaction under ERISA and the Code or similar violation of any applicable Similar Laws.

Representation

Accordingly, by acceptance of a note, each purchaser and subsequent transferee of a note will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire or hold the notes constitutes assets of any Plan or (ii) the purchase and holding of the notes by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a similar violation under any applicable Similar Laws.

The foregoing discussion is general in nature and is not intended to be all inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries, or other persons considering purchasing the notes on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the purchase and holding of the notes.

Purchasers of the notes have the exclusive responsibility for ensuring that their purchase and holding of the notes complies with the fiduciary responsibility rules of ERISA or of applicable Similar Laws and does not violate the prohibited transaction rules of ERISA, the Code or applicable Similar Laws.

S-57

Underwriting

We and the underwriters named below have entered into an underwriting agreement relating to the offer and sale of the notes. In the underwriting agreement, we have agreed to sell to each underwriter severally, and each underwriter has agreed severally to purchase from us, the principal amount of notes that appears opposite the name of that underwriter below:

The underwriting agreement provides that the underwriters are obligated to purchase all of the notes if any are purchased. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering of notes may be terminated.

The underwriters propose to offer the notes directly to the public at the public offering prices described on the cover page of this prospectus supplement and to certain dealers at the public offering price less a concession not to exceed 0.400% of the principal amount of the notes.

The underwriters may allow, and dealers may reallow, a concession not to exceed 0.250% of the principal amount of the notes on sales to other dealers. After the initial offering of the notes, the underwriters may change the public offering prices and concessions.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of an officer’s certificate and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The following table shows the underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering.

The expenses of this offering, not including underwriting discounts, are estimated to be approximately $1.7 million.

S-58

New issue of notes

There are currently no public trading markets for the notes. We have not applied and do not intend to apply to list the notes on any securities exchange. The underwriters have advised us that they currently intend to make a market in the notes. However, they are not obligated to do so and may, in their sole discretion, discontinue any market-making in the notes at any time without notice. Therefore, we cannot assure you that liquid trading markets for the notes will develop, that you will be able to sell your notes at a particular time or that the price you receive when you sell will be favorable.

Price stabilization and short positions

In connection with the offering of the notes, the underwriters may engage in overallotment, stabilizing transactions and syndicate covering transactions. Overallotment involves sales in excess of the offering size, which creates a short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may have the effect of preventing or retarding a decline in the market price of the notes or may cause the price of the notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue them at any time.

Settlement

We expect that delivery of the notes will be made to investors on or about March 16, 2020, which will be the seventh business day following the date of this prospectus supplement (such settlement cycle being referred to as “T + 7”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes any date prior to the second business day before delivery will be required, by virtue of the fact that the notes initially settle in T + 7, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to the second business day preceding the delivery date of the notes should consult their advisors.

Sales outside the United States

The notes may be offered and sold in the United States and certain jurisdictions outside the United States in which such offer and sale is permitted.

Canada

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement (including any amendment thereto) and/or the accompanying prospectus contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

S-59

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

European Economic Area and United Kingdom

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”) or in the United Kingdom (the “UK”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive 2016/97 (the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (the “Prospectus Regulation”) . Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA or in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA or in the UK may be unlawful under the PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in any member state of the EEA or in the UK will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of notes. This prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the Prospectus Regulation.

Solely for the purposes of our obligations pursuant to sections 309B(1)(a) and 309B(1)(c) of the SFA, we have determined, and hereby notify all relevant persons (as defined in Section 309A of the SFA) that the notes are “prescribed capital markets products” (as defined in the Securities and Futures (Capital Markets Products) Regulations 2018) and Excluded Investment Products (as defined in MAS Notice SFA 04-N12: Notice on the Sale of Investment Products and MAS Notice FAA-N16: Notice on Recommendations on Investment Products).

Other relationships

Certain underwriters and their affiliates have engaged in and may in the future engage in commercial and investment banking services for us and our affiliates, hedging services and other commercial dealings in the ordinary course of business. Specifically, certain of the underwriters and/or their affiliates act as co-syndication agents and lenders under our revolving credit facility.

Certain underwriters and/or their affiliates may hold a portion of our floating rate notes due 2020. As a result, certain of the underwriters and/or their affiliates may receive a portion of the proceeds of the offering. See “Use of proceeds.”

In addition, in the ordinary course of their business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade debt and equity securities, derivative securities, loans, commodities, currencies, credit default swaps and other financial instruments for their own accounts and for the accounts of their customers. Such investments and trading activities may involve or relate to assets, securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions that consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such assets, securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such assets, securities and instruments.

Under this shelf process, we may, from time to time, sell the securities described in this prospectus in one or more offerings. We have omitted parts of the registration statement in accordance with the rules and regulations of the SEC. This prospectus provides you only with a general description of the securities we may offer. Each time we sell securities using this prospectus, we will provide a prospectus supplement or prospectus supplements containing specific information about the terms of that offering. The prospectus supplement may also add to, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information in the prospectus supplement. You should read both this prospectus and any prospectus supplement together with additional information described under the heading “Where you can find more information” and “Incorporation by reference” before purchasing any of our securities. References to “securities” include any security that we might sell under this prospectus and any prospectus supplement. References to “$” and “dollars” are to United States dollars.

Risk factors

Investment in the offered securities involves risks. Before acquiring any securities offered pursuant to this prospectus, you should carefully consider the information contained or incorporated by reference in this prospectus or in any accompanying prospectus supplement or any related free writing prospectus, including, without limitation, the risks described under the caption “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 and in our Current Report filed on May 12, 2017 (to the extent incorporated by reference herein), as the same may be updated from time to time by our subsequent filings with the SEC. The occurrence of any of these risks might cause you to lose all or a part of your investment in the offered securities. To the extent a particular offering implicates additional known material risks, we will include a discussion of those risks in the applicable prospectus supplement. Please also refer to the section below entitled “Forward-looking Statements.”

Forward-looking statements

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

1

Statements and assumptions on future revenues, income and cash flows, performance, economic trends, the outcome of litigation, regulatory compliance, and environmental remediation cost estimates are examples of forward-looking statements. Numerous factors, including those discussed in the documents referred to under the heading “Risk factors” which include our filings with the Commission referred to under the heading “Incorporation by reference” could affect our forward-looking statements and actual performance. You should consider all of our forward-looking statements in light of the factors discussed in those documents. In addition, other risks and uncertainties not presently known to us or that we currently consider immaterial could affect the accuracy of our forward-looking statements.

Except as required by law, we undertake no obligation to update any forward-looking statements in order to reflect any event or circumstance that may arise after the date of this prospectus.

Use of proceeds

Unless otherwise indicated in a prospectus supplement, the net proceeds from the sale of securities offered by this prospectus and any applicable prospectus supplement will be used for general corporate purposes. Until we apply the proceeds from a sale of securities to their intended purposes, we may invest those proceeds in short-term investments, including repurchase agreements, some or all of which may not be investment grade.

Ratio of earnings to fixed charges

The following table shows our historical ratio of earnings to fixed charges for the periods indicated. As we have no shares of preferred stock outstanding as of the date of this prospectus, no ratio of earnings to fixed charges and preferred dividends is presented.

We computed the ratio of earnings to fixed charges by dividing “Earnings and Fixed Charges” by the amount of “Total Fixed Charges.” For the purposes of calculating this ratio, we have calculated “Earnings and Fixed Charges” by adding (i) Earnings before income taxes; (ii) gain or loss from less than 50%-owned associated companies; (iii) interest expense; and (iv) the portion of rents representative of an interest factor. For the purposes of calculating this ratio, we have calculated “Total Fixed Charges” by adding (i) interest expense; (ii) capitalized interest; and (iii) the portion of rents representative of an interest factor.

Description of debt securities

The following description of the terms of the debt securities sets forth certain general terms and provisions of the debt securities to which any prospectus supplement may relate. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to those debt securities will be described in the prospectus supplement relating to those debt securities. Accordingly, for a description of the terms of a particular issue of debt securities, reference must be made to both the prospectus supplement relating thereto and to the following description.

We may issue senior or subordinated debt securities. We will issue the senior debt securities under an indenture to be entered into between us and Regions Bank, as trustee, and any supplemental indentures thereto. We refer to the applicable indenture under which senior debt securities are issued as the “senior indenture”. We will

2

issue the subordinated debt securities under an indenture to be entered into between us and a commercial bank to be selected, as trustee, and any supplemental indenture thereto. We refer to the applicable indenture under which subordinated debt securities are issued as the “subordinated indenture”. We refer to the senior indenture and the subordinated indenture, collectively, as the “base indentures”.

As used in this prospectus, “debt securities” means our direct unsecured general obligations and may include debentures, notes, bonds or other evidences of indebtedness that we issue and the trustee authenticates and delivers under the applicable base indenture. The prospectus supplement relating to any offering of debt securities will describe more specific terms of the debt securities being offered.

Debt securities will be issued under a base indenture in one or more series established pursuant to a supplemental indenture or a resolution duly adopted by our board of directors or a duly authorized committee thereof. The base indentures do not limit the aggregate principal amount of debt securities that may be issued thereunder, or the amount of series that may be issued. We refer to the base indentures (together with each applicable supplemental indenture or resolution establishing the applicable series of debt securities) collectively in this prospectus as the “indentures”. The indentures will be subject to and governed by the Trust Indenture Act of 1939, as amended.

The forms of the base indentures have been filed as exhibits to the registration statement of which this prospectus forms a part. The following summaries of certain provisions of the base indentures do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all provisions of the base indenture and the supplemental indenture or board resolution (including the form of debt security) relating to the applicable series of debt securities.

General

The senior debt securities will be our unsecured obligations and will rank equally with all of our other senior debt from time to time outstanding. The subordinated debt securities will be subordinated in right of payment to the prior payment in full of our unsubordinated debt, including any senior debt securities, as described below under “—Subordinated indenture provisions—Subordination.”

Our secured debt will be effectively senior to the debt securities to the extent of the value of the assets securing such debt. Unless otherwise indicated in a prospectus supplement, the debt securities will be exclusively our obligations and not of our subsidiaries and therefore the debt securities will be structurally subordinate to the debt and liabilities of any of our subsidiaries.

The applicable prospectus supplement will describe the specific terms of each series of debt securities being offered, including some or all of the following:
