² See appendix to this earnings release for a reconciliation to net earnings.

Ward Nye, Chairman, President and CEO of Martin Marietta, stated, “By nearly all meaningful measures, 2017 was an extraordinary year for Martin Marietta.  Among our accomplishments are two significant milestones - the best safety performance in our history and EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) exceeding $1.0 billion.  We also delivered record revenues, profitability and earnings per diluted share for both the fourth quarter and full year, building on the momentum created by record performance in prior years.  

“Even more noteworthy, we achieved these safety and financial results despite externally-driven volume headwinds prevalent throughout much of the year that reduced full-year aggregates volumes by one million tons compared with 2016 and almost nine million tons as measured against our initial 2017 guidance.  Our ability to post record results despite these external factors, among them extraordinary weather events, contractor labor constraints, and a slower-than-expected pace of public contract lettings, validates the

- MORE -

successful execution of our strategic plan and underpins our optimismfor a steady and extended cyclical recovery as we begin 2018.

“Our confidence in our 2018 outlook is particularly strengthened by positive fourth-quarter trends.  Once again, we posted solid pricing growth across all product lines and segments. These ongoing pricing improvements, coupled with the benefits from the strategic deployment of capital into our business, contributed in part to a 290-basis-point expansion in fourth-quarter consolidated gross margin compared with the prior-year quarter. Notably, the aggregates product line posted a fourth-quarter incremental gross margin well in excess of management’s targeted goal of 60 percent despite lower volumes.  These results underscore the comparative strength of our markets and our continued focus on operational excellence.

“While employment expansion has led to continued strength in private residential and nonresidential construction, we have yet to see meaningful and consistent growth in public heavy construction activity. Infrastructure projects have been hindered by project delays and uncertainty concerning regulatory and other related reform.  We are encouraged, however, by the recent enactment of the Tax Cuts and Jobs Act of 2017 (2017 Tax Act) and its long-term benefits for Martin Marietta, our customers and our industry.  Importantly, passage of this legislation provides positive momentum in Washington, D.C. to address the shortfall in sustainable funding commensurate with the nation’s need for infrastructure investment.  The recent release of President Trump’s Legislative Outline for Rebuilding Infrastructure in America provides additional momentum, increasing the likelihood that both infrastructure funding will be increased and regulatory burdens will be lightened. While state Departments of Transportation (DOTs) and contractors are slowly addressing their labor constraints, we believe that were an enhanced infrastructure bill enacted, those efforts would be more rapidly addressed.  However, even in the absence of such an enhanced infrastructure bill, strong customer confidence and improving sentiment lead us to believe that infrastructure activity for 2018 and beyond should benefit from the Fixing America’s Surface Transportation Act (FAST Act), the 2017 Tax Act, and state and local infrastructure initiatives.”

Mr. Nye concluded, “Looking ahead to 2018, the fundamental drivers for broad-based construction activity support our optimism that we will continue to benefit from a steady multi-year cyclical recovery across our geographic footprint.   Our leading positions in many of the nation’s most attractive and vibrant markets should allow us to capitalize on anticipated increased demand for infrastructure projects and private-sector construction activity in 2018 and beyond. With a relentless focus on world-class safety standards, diligent cost discipline, operational excellence and prudent capital allocation, Martin Marietta remains committed to achieving industry-leading results and further enhancing long-term shareholder value.”

Operating Results

(All comparisons are versus the prior-year period unless noted otherwise)

Building Materials Business  

Fourth-quarter total revenues for the Building Materials business, which includes the aggregates, cement, ready mixed concrete and asphalt and paving product lines, were $903.0 million, up 2.1 percent from $884.7 million.  Average selling prices improved across all product lines and segments during the quarter.  Aggregates product line fourth-quarter pricing improved 4.0 percent despite lower shipment volumes.  The Mid-America Group and the Southeast Group generated aggregates product line pricing growth of 6.9 percent and 4.2 percent, respectively, for the fourth quarter, driven by continued price discipline.  Product mix and ongoing competitive pressures led to relatively flat aggregates pricing for the West Group. The cement product line generated pricing growth of 4.1 percent for the quarter, reflecting strong ongoing construction activity in the Dallas/Fort Worth area. Ready mixed concrete and asphalt pricing increased 2.1 percent and 16.3 percent, respectively.  Unseasonably warm weather in Colorado and strong demand allowed for favorable asphalt pricing during the quarter.

Overall, fourth-quarter aggregates product line shipments decreased slightly, driven by government uncertainty, labor constraints and ongoing project delays, particularly in the Mid-America and West Groups. The Southeast Group reported aggregates volume growth of 5.6 percent, driven by strong nonresidential construction and improving public construction activity. Total cement shipments increased 1.7 percent. Ready mixed concrete shipments decreased 4.7 percent overall with lower energy-sector shipments offsetting strong demand in the Dallas/Fort Worth and Denver markets.   Asphalt shipments increased 1.2 percent for the fourth quarter.

Infrastructure Market Highlights

♦ Aggregates product line shipments to the infrastructure market increased slightly over the prior-year fourth quarter.  Continued underinvestment in the nation’s infrastructure, coupled with marginal construction activity from the FAST Act and ongoing project delays, limited the growth in overall infrastructure shipments. However, the West Group and Southeast Group, which include states with robust DOT budgets, reported growth in infrastructure shipments. Overall, aggregates product line shipments to the infrastructure market comprised 38 percent of fourth-quarter aggregates product line volumes, well below the Company’s most recent five-year average of 43 percent.

Nonresidential Market Highlights

♦ Aggregates product line shipments to the nonresidential market decreased 7 percent during the fourth quarter. While the Southeast Group reported strong industrial construction growth, the West Group, consistent with management’s expectations, reported a double-digit decline in nonresidential shipments due to the completion of several large energy-related projects in 2016 that were not immediately replaced in 2017.  Management expects the next wave of these projects to bid in 2018.  The nonresidential market represented 31 percent of fourth-quarter aggregates product line shipments.  

Residential Market Highlights

♦ Aggregates product line shipments to the residential market increased 9 percent during the fourth quarter, driven by continued strength in housing across the Company’s geographic footprint, particularly in the western and southeastern United States.  Notably, Texas, Florida, North Carolina, Georgia, South

- MORE -

Carolina and Colorado, key geographies for the Building Materials business, comprised six of the top ten states for growth in single-family housing unit starts for the twelve months ended December 2017.  The residential market accounted for 24 percent of fourth-quarter aggregates product line shipments.

ChemRock/Rail Market Highlights

♦ Aggregates product line volumes for the ChemRock/Rail market declined 10 percent versus the prior-year quarter, driven by reduced agricultural lime shipments.  The ChemRock/Rail market accounted for the remaining 7 percent of fourth-quarter aggregates product line shipments.  

Magnesia Specialties Business

Fourth-quarter total revenues for the Magnesia Specialties business were $67.5 million, an increase of 5.3 percent, and gross margin expanded 50-basis-point to 34.9 percent, driven by higher-margin specialty chemicals sales.

Consolidated Operating Results

On December 22, 2017, the President signed into law the 2017 Tax Act, which, among other things, provides for a permanent reduction in the federal corporate tax rate.  As a result of this legislation, the Company recorded a one-time, non-cash income tax benefit of $258.1 million from the remeasurement of its deferred tax assets and liabilities at the new statutory rate of 21 percent.  Excluding this one-time benefit, which represents $4.07 per diluted share, the Company generated earnings per diluted share of $1.88 for the fourth quarter and $7.18 for the full year, both of which are record results.

Liquidity and Capital Resources

Cash provided by operating activities was $657.9 million in 2017 compared with $689.2 million in 2016.

Property, plant and equipment additions for 2017 were $432.4 million, reflecting the continued strategic deployment of capital into the business, including mobile fleet purchases that will reduce maintenance and repair costs.  Cash paid for additions during the year was $410.3 million.

In December 2017, the Company issued $1.4 billion of debt in anticipation of closing the Bluegrass Materials Company acquisition in the first half of 2018, which remains subject to the customary regulatory process and other closing conditions.  The newly-issued debt reflects a weighted-average interest rate of 3.5 percent.

At December 31, 2017, the Company’s ratio of consolidated net debt-to-consolidated EBITDA, as defined in the applicable credit agreement, for the trailing-12 months was 1.58 times.  The ratio excludes the debt obtained to fund the pending Bluegrass Materials acquisition.

Capital Allocation Priorities Enhance Shareholder Value

Martin Marietta is dedicated to maintaining disciplined capital allocation to further enhance shareholder value. The Company’s unchanged capital allocation priorities include the right acquisitions that enable the successful execution of the Company’s strategic growth plan, organic capital investment, and the return of cash to shareholders through a meaningful and sustainable dividend and share repurchases.

Consistent with these objectives, the Company previously announced the acquisition of Bluegrass Materials, the largest privately-held, pure-play aggregates business in the United States.  Martin Marietta and Bluegrass

- MORE -

Materials continue to work closely and cooperatively with the Department of Justice in its review of the proposed transaction.

The Company returned $1.2 billion to shareholders, in the form of dividend payments and share repurchases, since announcing a repurchase authorization in February 2015 to acquire up to 20 million shares of its outstanding common stock.  At December 31, 2017, 14.7 million shares remain under the current repurchase authorization and 62.9 million shares of Martin Marietta common stock were outstanding.   

Outlook for 2018

Martin Marietta remains optimistic about its near-term and long-term outlook given its continued ability to successfully execute its strategic business plan and the largely positive trends in the markets it serves.  The fundamental drivers for the Company’s expected growth remain intact as the current broad-based recovery continues on a steady and extended basis. Notably:

♦ Infrastructure construction activity should see benefits from the funding provided by the FAST Act as state DOTs and contractors address labor constraints and further regulatory reform emerges. Additionally, state and local initiatives that support infrastructure funding, including gas tax increases and other ballot initiatives passed over the previous 24 months, continue to gain overwhelming voter support and will play an expanded role in public-sector activity.  Third-party forecasts support increased infrastructure spending in 2018, particularly spending for aggregates-intensive highways and streets.

♦ Nonresidential construction is expected to modestly increase in both the heavy industrial and commercial sectors for the next several years as supported by third-party forecasts. Management expects new energy-related projects will bid in 2018 with construction activity in 2019 and beyond as permitting and final investment decisions are either made and/or approved.

♦ Residential construction is expected to continue growing, particularly in key Martin Marietta markets, driven by employment gains, historically low levels of construction activity over the previous years, low mortgage rates and higher lot development.  Notably, six of Martin Marietta’s key states rank in the top ten for single-family housing unit permits.

Management’s view of 2018 anticipates growth in all three primary construction end-use markets and faster expansion in the West and Southeast Groups and comparatively slower growth in the Mid-America Group, which historically has generated the Company’s highest margins.  Specifically:

♦ Aggregates product line end-use markets compared with 2017 levels are as follows:

• Infrastructure market to increase in the mid-single digits.

• Nonresidential market to increase in the low- to mid-single digits.

• Residential market to increase in the high-single digits.

• ChemRock/Rail market to remain stable.

As a result of the recent 2017 Tax Act, management expects the Company’s effective tax rate, excluding discrete events, to range from 20 percent to 22 percent compared with its 2017 guidance of 28 percent.    

Martin Marietta’s 2018 guidance excludes any benefit from a potential increase in federal infrastructure funding as well as any impact from the pending acquisition of Bluegrass Materials which is expected to be accretive to earnings per share and cash flow in the first full year of Martin Marietta’s ownership.

Risks to Outlook

The outlook includes management’s assessment of the likelihood of certain risks and uncertainties that may affect performance, including but not limited to: both price and volume, and a widespread decline in aggregates volume negatively affecting aggregates price; the termination, capping and/or reduction of the federal and/or state gasoline tax(es) or other revenue related to infrastructure construction; a significant change in the funding patterns for traditional federal, state and/or local infrastructure projects; the United States Congress’ inability to reach agreement among themselves or with the current Administration on policy issues that impact the federal budget; the volatility in the commencement of infrastructure projects; a reduction in defense spending, and the subsequent impact on construction activity on or near military bases; a decline in nonresidential construction; a further decline in energy-related construction activity resulting from a sustained period of low global oil prices or changes in oil production patterns in response to this decline and certain regulatory or other economic factors; a slowdown in the residential construction recovery; a sustained reduction in capital investment by the railroads; an increase in the cost of compliance with governmental laws, rules and regulations; construction labor shortages and/or supply-chain challenges; and unexpected equipment failures, unscheduled maintenance, industrial accident or other prolonged and/or significant disruption to its cement and/or its Magnesia Specialties production facilities.  Further, increased highway construction funding pressures resulting from either federal or state issues can affect profitability.  If these negatively affect transportation budgets more than in the past, construction spending could be reduced.  Cement is subject to cyclical supply and demand and price fluctuations.  The Magnesia Specialties business essentially runs at capacity; therefore, any unplanned changes in costs or realignment of customers introduce volatility to the earnings of this segment.

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

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

All of the Company’s businesses are also subject to weather-related risks that can significantly affect production schedules and profitability.  The first and fourth quarters are most adversely affected by winter weather.  Hurricane activity in the Atlantic Ocean and Gulf Coast generally is most active during the third and fourth quarters. In fact, in August and September 2017, respectively, Hurricanes Harvey and Irma generated winds, rainfall and flooding which disrupted operations in Texas, Louisiana, Florida, Georgia and the Carolinas.  However, after flood waters recede, management typically expects an increase in construction activity as roads, homes and businesses are repaired.

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