General

Martin Marietta Materials, Inc. (the “Company” or “Martin Marietta”) is a natural-resource-based building materials company. The Company supplies aggregates (crushed stone, sand and gravel) through its network of 282 quarries and distribution yards to customers in 30 states, Canada, the Bahamas and the Caribbean Islands. In the western United States, Martin Marietta also provides cement and downstream products, namely, ready mixed concrete, asphalt and paving services in markets where the Company has a leading aggregates position. Specifically, the Company has two cement plants in Texas, and ready mixed concrete and asphalt operations in Texas, Colorado, Louisiana and Arkansas. Paving services are exclusively in Colorado. The Company’s heavy-side building materials are used in infrastructure, nonresidential and residential construction projects. Aggregates are also used in agricultural, utility and environmental applications and as railroad ballast. The aggregates, cement, ready mixed concrete, asphalt and paving product lines are reported collectively as the “Building Materials” business. The Company also operates a Magnesia Specialties business with production facilities in Michigan and Ohio. The Magnesia Specialties business produces magnesia-based chemicals products which are used in industrial, agricultural and environmental applications. It also produces dolomitic lime sold primarily to customers in the steel and mining industries. Magnesia Specialties’ products are shipped to customers worldwide.

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

The Company completed over 85 smaller acquisitions from the time of its initial public offering until the present, which allowed the Company to enhance and expand its presence in the aggregates marketplace. This included an exchange of certain assets in 2011 with Lafarge North America Inc. (“Lafarge”), pursuant to which it received aggregates quarry sites, ready mixed concrete and asphalt plants, and a road paving business in and around the metropolitan Denver, Colorado, and the I-25 corridor, in exchange for which Lafarge received properties consisting of quarries, an asphalt plant and distribution yards operated by the Company along the Mississippi River (called the Company’s “River District Operations”) and a cash payment.

The business has developed further through the following transactions over the past five years.

In 2013, the Company acquired three aggregates quarries in the greater Atlanta, Georgia, area. The transaction provided over 800 million tons of permitted aggregates reserves and enhanced the Company’s existing long-term position in this market.

In 2014, the Company completed the acquisition of Texas Industries, Inc. (“TXI”), further augmenting its position as a leading supplier of aggregates and heavy building materials. TXI, as a stand-alone entity, was a leading supplier of heavy construction materials in the southwestern United States and a major supplier of natural aggregates and ready mixed concrete in Texas, northern Louisiana and, to a lesser extent, in Oklahoma

and Arkansas. TXI was the largest supplier of cement, ready mixed concrete, and concrete products in Texas. TXI enhanced the Company’s position as an aggregates-led, low-cost operator in large and fast-growing geographies in the United States and provided high-quality assets in cement and ready mixed concrete.

In addition to the cement operations, the Company acquired as part of the TXI acquisition nine quarries and six aggregates distribution terminals located in Texas, Louisiana and Oklahoma. The Company also acquired approximately 120 ready mixed concrete plants, situated primarily in three areas of Texas (the Dallas/Fort Worth/Denton area of north Texas; the Austin area of central Texas; and from Beaumont to Texarkana in east Texas), in north and central Louisiana and in Southwestern Arkansas. As part of an agreement in conjunction with the United States Department of Justice’s review of the transaction, the Company divested its North Troy Quarry in Oklahoma and two related rail distribution yards in Dallas and Frisco, Texas.

TXI was also a cement producer in California. In 2015, the Company divested its California cement operations acquired from TXI. These operations were not in close proximity to aggregates and other core assets of the Company and, unlike other marketplace competitors, were not vertically integrated with ready mixed concrete production. The divestiture primarily included a cement plant, two distribution terminals, mobile equipment, intangible assets and inventory. The Company also completed the integration of the TXI operations in 2015, and completed three smaller acquisitions, which included three aggregates operations and related assets.

In 2016, the Company acquired aggregates, ready mixed concrete and asphalt and paving operations in southern Colorado that provided more than 500 million tons of mineral reserves and expanded the Company’s presence along the Front Range of the Rocky Mountains, home to 80% of Colorado’s population. The Company also acquired the remaining interest it had not previously owned in a ready mixed concrete company that serves the I-35 corridor in central Texas between Dallas and Austin, which enhanced the Company’s position and provided additional vertical integration benefits with the Company’s cement product line.

Between 2001 and 2017, the Company disposed of or idled a number of underperforming operations, including aggregates, ready mixed concrete, trucking, and asphalt and road paving operations of its Building Materials business and the refractories business of its Magnesia Specialties business. In some of its divestitures, the Company concurrently entered into supply agreements to provide aggregates at market rates to certain of these divested businesses. During 2015, the Company disposed of certain non-core asphalt operations in San Antonio, Texas and divested its California cement operations. The Company will continue to evaluate opportunities to divest underperforming assets, if appropriate, during 2018 in an effort to redeploy capital for other opportunities.

On June 26, 2017, the Company announced a definitive agreement to acquire Bluegrass Materials Company (“Bluegrass Materials”) for $1.625 billion in cash. The Company will not acquire any of Bluegrass Materials’ cash and cash equivalents nor will it assume any of Bluegrass Materials’ outstanding debt. Bluegrass Materials is the largest privately held, pure-play aggregates business in the United States and has a portfolio of 23 active sites with more than 125 years of strategically-located, high-quality reserves, in Maryland, Georgia, South Carolina, Kentucky, Tennessee and Pennsylvania. These operations complement the Company’s existing southeastern footprint and provide a new growth platform within the southern portion of the Northeast megaregion. The Company and Bluegrass Materials are continuing to work closely and cooperatively with the Department of Justice in its review of the proposed transaction. The parties currently anticipate that the proposed acquisition will be completed in the first half of 2018.

General Risk Factors

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

This Form 10-K and other written reports and oral statements made from time to time by the Company contain statements which, to the extent they are not recitations of historical fact, constitute forward-looking statements within the meaning of federal securities law. Investors are cautioned that all forward-looking statements involve risks and uncertainties, and are based on assumptions that the Company believes in good faith are reasonable, but which may be materially different from actual results. Investors can identify these statements by the fact that they do not relate only to historic or current facts. The words “may,” “will,” “could,”

Table of Contents

“should,” “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “intend,” “outlook,” “plan,” “project,” “scheduled,” and similar expressions in connection with future events or future operating or financial performance are intended to identify forward-looking statements. Any or all of the Company’s forward-looking statements in this Form 10-K and in other publications may turn out to be wrong.

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

Investors are also cautioned that it is not possible to predict or identify all such factors. Consequently, the reader should not consider any such list to be a complete statement of all potential risks or uncertainties. Other factors besides those listed may also adversely affect the Company and may be material to the Company. The Company has listed the known material risks it considers relevant in evaluating the Company and its operations. The forward-looking statements in this document are intended to be subject to the safe harbor protection provided by Sections 27A and 21E of the Securities Exchange Act of 1934. These forward-looking statements are made as of the date hereof based on management’s current expectations, and the Company does not undertake an obligation to update such statements, whether as a result of new information, future events, or otherwise.

For a discussion identifying some important factors that could cause actual results to vary materially from those anticipated in the forward-looking statements, see the factors listed below, along with the discussion of “Competition” under Item 1 of this Form 10-K, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” under Item 7 of this Form 10-K and the 2017 Annual Report, and “Note A: Accounting Policies” and “Note N: Commitments and Contingencies” of the “Notes to Financial Statements” of the 2017 Financial Statements included under Item 8 of this Form 10-K and the 2017 Annual Report.

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 nonresidential and residential construction markets, could fall if companies and consumers are unable to get 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. Several of our top sales generating states, from time-to-time, stop or slow bidding 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 the strength of the construction industry. 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 Great Recession was an example, and our business suffered. Construction spending can also be disrupted by terrorist activity and armed conflicts.

Table of Contents

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 sales-generating states of our Building Materials business (based on net sales by state of destination) of Texas, Colorado, North Carolina, Iowa, and Georgia, our profitability will decrease. We experienced this situation with the Great Recession.

The Great Recession of 2008 resulted in large declines in shipments of aggregates products in our industry. Recent years, however, have shown a slow turnaround in this trend. The United States is currently experiencing the third-longest economic recovery since the Great Depression. As of December 31, 2017, the current expansion, which started in June 2009, the approximate end of the Great Recession, has lasted 102 months. By comparison, the average trough-to-peak expansionary cycle since 1938 was 60 months and, in May 2018, the current cycle will become the second-longest economic recovery since the Great Depression. During this current economic expansion, however, governmental uncertainty, labor shortages and record levels of precipitation have slowed the pace of heavy construction activity, resulting in what we believe to be a slow, steady, extended construction cycle. The Company’s overall aggregates product line shipments remain approximately 10% below mid-cycle demand. Importantly, the level of recovery varies within the Company’s geographic footprint. Specifically, North Carolina and Georgia, key states in the Mid-America and Southeast Groups, respectively, are approximately 20% below mid-cycle demand, while Texas, a key state in the West Group, is modestly above mid-cycle demand. During 2017 our aggregates product line shipments showed a 0.6% decline compared with 2016 levels, after a 1.4% increase in 2016.

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 after uncertainty regarding the solvency of the federal highway bill in 2014. Contractors were not able to get any certainty on the availability of federal infrastructure funding until late 2015 with the enactment of a new federal highway bill, which has had insignificant impact at the federal level to date. This time lag with commencement of federal infrastructure funding was accompanied by a reduction in some states’ investment in highway maintenance.

The public infrastructure market accounted for approximately 40% of the Company’s aggregates product line shipments in 2017, consistent with 2016 and 2015. Government uncertainty, attenda

Building Materials Business

As of December 31, 2017, the Company processed or shipped aggregates from 282 quarries, underground mines, and distribution yards in 26 states, Canada, and the Bahamas, of which 108 are located on land owned by the Company free of major encumbrances, 59 are on land owned in part and leased in part, 107 are on leased land, and eight are on facilities neither owned nor leased, where raw materials are removed under an agreement. The Company’s aggregates reserves, on the average, exceed 60 years based on normalized levels of production, and approximate 100 years at current production rates. However, certain locations may be subject to more limited reserves and may not be able to expand. In addition, as of December 31, 2017, the Company processed and shipped ready mixed concrete and/or asphalt products from 152 properties in five states, of which 127 are located on land owned by the Company free of major encumbrances, one is on land owned in part and leased in part, and 24 are on leased land.

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

The Company estimates proven and probable reserves based on the results of drilling. Proven reserves are reserves of deposits designated using closely spaced drill data, and based on that data the reserves are believed to be relatively homogenous. Proven reserves have a certainty of 85% to 90%. Probable reserves are reserves that are inferred utilizing fewer drill holes and/or assumptions about the economically mineable reserves based on local geology or drill results from adjacent properties. The degree of certainty for probable reserves is 70% to 75%. In determining the amount of reserves, the Company’s policy is to not include calculations that exceed certain depths, so for deposits, such as granite, that typically continue to depths well below the ground, there may be additional deposits that are not included in the reserve calculations. The Company also deducts reserves not available due to property boundaries, set-backs, and plant configurations, as deemed appropriate when estimating reserves. The Company uses the same methods of analysis to evaluate and estimate the amount of its aggregates reserves used in the cement manufacturing process for its cement product line as it does for its aggregates product line. For additional information on the Company’s assessment of reserves, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Other Financial Information - Critical Accounting Policies and Estimates- Property, Plant and Equipment” under Item 7 of this Form 10-K and the 2017 Annual Report for discussion of reserves evaluation by the Company.

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

Cement Product Line

As of December 31, 2017, the Company, through its subsidiaries, processed or shipped cement from six properties in one state, of which four are located on land owned by the Company free of major encumbrances and two are on leased land. The Company’s cement product line has production facilities located at two sites in Texas: Midlothian, Texas, south of Dallas/Fort Worth; Hunter, Texas, north of San Antonio. The following table summarizes certain information about the Company’s cement manufacturing facilities at December 31, 2017:

Reserves identified with the facilities shown above are contained on approximately 2,844 acres of land owned by the Company. As of December 31, 2017, the Company estimated its total proven and probable limestone reserves on such land to be approximately 692 million tons.

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

As of December 31, 2017, the Company, through its subsidiaries, also operated, directly or through third parties, five cement distribution terminals and owned the real estate at the California cement grinding and packaging facility it sold on September 30, 2015, which it expects to sell for non-cement use.

Table of Contents

Magnesia Specialties Business

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

Other Properties

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

Condition and Utilization

The Company’s principal properties, which are of varying ages and are of different construction types, are believed to be generally in good condition, are generally well maintained, and are generally suitable and adequate for the purposes for which they are used.

During 2017, the principal properties of the aggregates product line were believed to be utilized at average productive capacities of approximately 65% and were capable of supporting a higher level of market demand. However, during the Great Recession, the Company adjusted its production schedules to meet reduced demand for its products. For example, the Company has reduced operating hours at a number of its facilities, closed some of its facilities, and temporarily idled some of its facilities. In 2017, the Company’s aggregates product line operated at a level significantly below capacity, which restricted the Company’s ability to capitalize $36.5 million of costs that could have been inventoried under normal operating conditions. If demand does not improve over the near term, such reductions and temporary idling could continue. The Company expects, however, as the economy continues to recover, it will be able to resume production at its normalized levels and increase production again as demand for its products increases.

During 2017 the Texas cement plants operated on average at 75% to 80% utilization. The Portland Cement Association (“PCA”) forecasts a 2.6% increase in demand in Texas in 2018 over 2017. The cement product line’s leadership, in collaboration with the aggregates and ready mixed concrete teams, have developed strategic plans regarding interplant efficiencies, as well as tactical plans addressing plant utilization and efficiency. Due to the 24/7/365 nature of cement operations, significant gains in plant utilization and efficiency are typically achieved only during plant shutdowns.

The Company expects future organic earnings growth to result from increased pricing, rationalization of the current product portfolio and/or further cost reductions. In the current operating environment where steel utilization is at levels close to or below 70% and the strength of the United States dollar pressures product competitiveness in international markets, any unplanned change in costs or customers introduces volatility to the earnings of the Magnesia Specialties segment. The dolomitic lime business of the Magnesia Specialties segment operated at 71% utilization in 2017.

From time to time claims of various types are asserted against the Company arising out of its operations in the normal course of business, including claims relating to land use and permits, safety, health, and environmental matters (such as noise abatement, blasting, vibrations, air emissions, and water discharges). Such matters are subject to many uncertainties, and it is not possible to determine the probable outcome of, or the amount of liability, if any, from, these matters. In the opinion of management of the Company (which opinion is based in part upon consideration of the opinion of counsel), based upon currently-available facts, it is remote that the ultimate outcome of any litigation and other proceedings will have a material adverse effect on the overall results of the Company’s operations, its cash flows, or its financial condition. However, there can be no assurance that an adverse outcome in any of such litigation would not have a material adverse effect on the Company or its operating segments.

The Company was not required to pay any penalties in 2017 for failure to disclose certain “reportable transactions” under Section 6707A of the Internal Revenue Code.

Evaluation of Disclosure Controls and Procedures

As of December 31, 2017, an evaluation was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures. Based on that evaluation, the Company’s CEO and CFO concluded that the Company’s disclosure controls and procedures were effective at the reasonable assurance level.

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

Management’s Report on Internal Control over Financial Reporting

Our management’s report on internal control over financial reporting is included under Item 8 of this Annual Report on Form 10K, “Statement of Financial Responsibility and Management’s Report on Internal Controls over Financial Reporting,” and is incorporated by reference. The Company’s management concluded that the Company’s internal control over financial reporting was effective in providing reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with generally accepted accounting principles as of December 31, 2017.

Table of Contents

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting during the most recently completed fiscal quarter ended December 31, 2017 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations on the Effectiveness of Controls

The Company’s management, including the CEO and CFO, does not expect that the Company’s control system will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

CEO and CFO Certifications

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