MARTIN MARIETTA REPORTS FIRST-QUARTER RESULTS

Earnings Per Diluted Share of $0.07

Consolidated Gross Margin Expands By 500 Basis Points

Aggregates Product Line Volume Up 17% and Pricing Up 11%

Company Raises Annual Aggregates Pricing Guidance

Magnesia Specialties Generates Record First-Quarter Net Sales and Gross Profit

RALEIGH, North Carolina (April 30, 2015) – Martin Marietta Materials, Inc. (NYSE:MLM) today reported its results for the first quarter ended March 31, 2015.

Ward Nye, Chairman, President and CEO of Martin Marietta, stated: “We are pleased to report improved margins and increased profitability, both considerably ahead of our internal plans, and a first-quarter profit for the first time since 2008. These quarterly results serve as a further validation of our success in executing on our strategic objectives, as well as our relentless commitment to operational excellence and cost discipline. Notably, we achieved volume growth and reported a double-digit pricing increase in our heritage aggregates product line despite severe late winter weather in many markets and significant rainfall in Texas.  We view this volume and pricing momentum as an indication of a more construction-centric phase of economic recovery. Our first-quarter results and outlook for the full year have led us to increase our annual aggregates product line pricing guidance from an increase of 4% to 6% to an increase of 7% to 9% over 2014.

“Texas ranks second in the nation in job growth, supported by increased construction activity and a diverse industrial base.  Our leading position in Texas’ major northern, central and southern markets will allow us to capitalize on this trend as our customers’ backlogs across the construction end-use spectrum continue to improve. Construction activity is led by the state Department of Transportation’s nearly $9 billion fiscal year 2015 letting budget, which includes multi-year projects and adds to an existing infrastructure backlog. Texas also ranks first in nonresidential starts, with $39 billion in the trailing-12 months, and second in housing starts, which represented more than 15% of the nation’s housing starts for the trailing-12 months through March.

“We continue to see indicators of further recovery in the eastern half of the United States, where Martin Marietta has leading market positions. North Carolina, Georgia and Florida all rank in the top five in job growth and, similar to Texas, construction activity is improving. Further, both North Carolina and Georgia are among several states considering legislation to expand infrastructure funding, supporting the importance of transportation investment in spurring economic growth. Additionally, Iowa enacted a $0.10 per gallon increase in the state gas tax on March 1, 2015, to increase annual funding for infrastructure projects by an estimated $215 million.

“The Cement and Magnesia Specialties businesses made significant contributions to our quarterly earnings and cash generation. The Cement business continues to benefit from a sold out Texas market, which is operating near current peak utilization from a domestic capacity perspective. For the quarter, the business generated earnings before interest, income taxes, depreciation, depletion and amortization, or EBITDA, of $27.5 million. The Magnesia Specialties business is operating at physical capacity and leveraged record net sales to expand its gross margin (excluding freight and delivery revenues) 160 basis points over the prior-year quarter.”

Mr. Nye continued, “In addition to operational excellence and cost discipline, our performance reflects the execution of our other core foundational pillars: world-class safety, ethical conduct, sustainability, and customer satisfaction. Our employees remain focused on these principles and delivered exceptional first-quarter performance. We look forward to building on our progress to further increase shareholder value.”

NOTABLE ITEMS FOR THE QUARTER (ALL COMPARISONS ARE VERSUS THE PRIOR-YEAR FIRST QUARTER)

QUARTERLY OPERATING RESULTS (ALL COMPARISONS ARE VERSUS THE PRIOR-YEAR FIRST QUARTER UNLESS NOTED OTHERWISE)

Aggregates Business

Heritage aggregates product line shipments reflect growth in all end-use markets. Shipments to the infrastructure market comprised 40% of quarterly volumes and increased 8%. Growth was driven by large projects in the Mid-America Group (notably in North Carolina and Iowa) and the Southeast Group. Shipments in the West Group were hampered by rainfall. The federal highway bill, Moving Ahead for Progress in the 21^st Century, or MAP-21, will expire on May 31, 2015. However, management anticipates the U.S. Congress will pass another continuing resolution through the fall, while working towards passage of a multi-year bill.

The nonresidential market represented 34% of quarterly heritage aggregates product line shipments and increased slightly. Diversified state economies have generated other nonresidential and infrastructure projects to replace energy-related shipments currently displaced by volatility in oil prices. Further, the Company expects energy-related activity to remain strong, supported by more than $100 billion of planned projects along the Gulf Coast, including a significant portion in Texas. Nonresidential activity varies significantly by state, with growth strongest in Texas and California. The Dodge Momentum Index for March was 122.3. For the first three months of 2015, the index was 12% higher than the comparable period in 2014, signaling continued growth in nonresidential activity.

The residential end-use market accounted for 15% of quarterly heritage aggregates product line shipments, and volumes to this market increased 4%. The overall rate of residential growth has slowed compared with the last few years, in part due to a temporary reduction in available building lot inventory in the Company’s markets. Importantly though, subdivision development, which consumes the majority of stone used in residential construction activity, has increased in a number of states. Notably, Colorado, Georgia, Florida and South Carolina all reported double-digit growth in housing starts for the trailing-12 months through March. The ChemRock/Rail market accounted for the remaining 11% of heritage aggregates product line volumes and increased slightly, led by higher ballast shipments. This growth reflects the increasing investment in capacity expansion and maintenance by major railroads.

Overall, heritage aggregates product line shipments increased 7.0%, excluding shipments from the third-quarter 2014 divestiture of three operations from the prior-year quarter. The divestiture included an Oklahoma quarry and two Dallas, Texas rail yards and was required by the Department of Justice in the TXI acquisition. Shipments from these divestitures continue to be reported in heritage volumes in the prior-year quarter. Aggregates product line shipments in the Mid-America Group increased 18.1%, and the Southeast Group achieved an increase of 2.2%. The West Group shipments were up slightly, excluding shipments from the divested operations from the prior-year quarter. The reported variance for the West Group is a 6.1% decline.

Heritage aggregates product line pricing represents growth in all reportable groups, led by the 17.6% increase in the West Group. The most significant improvement was achieved in South Texas. The Southeast Group and Mid-America Group reported increases of 6.0% and 3.2%, respectively.

The legacy TXI aggregates product line operations continue to benefit from integration, which has resulted in expanded margins. Inclusive of two small acquisitions completed during the first quarter, these operations had net sales of $31.9 million and a gross margin (excluding freight and delivery revenues) of 21.7%.

The heritage ready mixed concrete product line reported an 11% increase in average selling price, which led to an 8% increase in net sales and a 490-basis-point improvement in gross margin (excluding freight and delivery revenues). Winter production reflects increased costs for additives, which is passed along to customers. The legacy TXI ready mixed concrete shipments and profitability reflect the impact of rain in Texas. For the quarter, these operations contributed $86 million of net sales. The hot mixed asphalt product line reported a 3% increase in average selling price and $10 million of net sales.

Weather adversely affected the aggregates product line total production cost per ton shipped, which remained relatively flat. Lower energy costs continue to benefit the cost structure.

The heritage Aggregates business gross margin (excluding freight and delivery revenues) was 9.7%, an increase of 730 basis points. The Southeast Group, which benefitted from recovery in Georgia and improved performance by offshore operations, led with an increase of 1,040 basis points. Incremental margin for the heritage aggregates business was 76% and was led by the Mideast and Southeast Divisions.

Magnesia Specialties Business

Magnesia Specialties continued to deliver strong performance and generated first-quarter record net sales of $58.8 million. First-quarter earnings from operations were $17.8 million compared with $16.3 million.

Cement Business

The Cement business is benefitting from continued strength in Texas markets, where demand exceeds local supply. The Portland Cement Association, or PCA, forecasts continued supply/demand imbalance in Texas over the next several years. For the quarter, the business generated $96.6 million of net sales and $19.0 of gross margin. The business incurred $5.4 million in planned cement kiln maintenance costs, which are expected to be heaviest in the third and fourth quarters. First-quarter operating results were negatively affected by wet weather in Texas, which delayed some shipments to the balance of the year. During the first quarter, the Company announced price increases of $10 per ton in the Texas and California markets effective April 1.

CONSOLIDATED OPERATING RESULTS

Consolidated SG&A was 7.8% of net sales compared with 9.0% in the prior-year quarter. The reduction of 120 basis points reflects the growth of net sales outpacing the increase in SG&A, partially offset by higher pension expense. The Company incurred acquisition-related expenses of $1.6 million, which is the expected run rate for the next few quarters. Earnings from operations for the quarter were $25.6 million compared with a loss from operations of $15.9 million in the prior-year period.

The Company recorded an income tax benefit of $0.8 million for the quarter, driven by discrete events, which include the exercise of converted stock awards issued to former TXI personnel. Excluding discrete items, the estimated effective income tax rate would have been 31%, in line with annual guidance. For the year, the Company expects to fully utilize allowable net operating loss carryforwards of $363 million acquired with TXI.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities for the first quarter was $35.1 million in 2015 compared with $6.6 million in 2014. The increase is principally attributable to higher earnings before depreciation, depletion and amortization expense, partially offset by cash payments in 2015 for 2014 taxes.

At March 31, 2015, the ratio of consolidated debt to consolidated EBITDA, as defined, for the trailing-12 months was 2.4 times, in compliance with the Company’s leverage covenant.

SHARE REPURCHASE PROGRAM

The Company is authorized to execute a share repurchase program under which it may acquire up to 20 million shares of its outstanding common stock. Future repurchases are expected to be carried out through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades, accelerated share purchase transactions, or any combination of such methods. The Company expects to complete the repurchase program over the next several years, though the actual timing of completion will be based on an ongoing assessment of the capital needs of the business, the market price of the Company’s common stock and general market conditions. Share repurchases will be executed based on then-current business and market factors so the actual return of capital in any single quarter may vary. The repurchase program may be modified, suspended or discontinued by the Board at any time without prior notice.

FULL-YEAR OUTLOOK

The Company is encouraged by positive trends in its business and markets, notably:

Based on these trends and expectations, the Company anticipates the following for the full year:

Mr. Nye concluded, “We are excited about the solid foundation we have created and the transformational power of Martin Marietta’s business model, which positions us to deliver substantial value to shareholders going forward. The integration of TXI continues on schedule and will, at a minimum, yield synergies in line with our updated guidance. We will continue to operate the business with rigorous discipline. The growing demand for building materials should allow us to strengthen our balance sheet, increase our financial flexibility and invest in our business, all while returning significant value to our shareholders through our repurchase program.”

RISKS TO OUTLOOK

The full-year outlook includes management’s assessment of the likelihood of certain risks and uncertainties that will affect performance. The most significant risks to the Company’s performance will be Congress’ actions and timing surrounding federal highway funding and uncertainty over the funding mechanism for the Highway Trust Fund. Management currently expects Congress to extend federal highway funding through continuing resolution through the fall of 2015. Further, a decline in consumer confidence may negatively impact investment in construction projects. While both MAP-21 and TIFIA credit assistance are excluded from the U.S. debt ceiling limit, this issue may have a significant impact on the economy and, consequently, construction activity. Other risks and uncertainties related to the Company’s future performance include, but are not limited to: both price and volume, and a recurrence of 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; a reduction in defense spending, and the subsequent impact on construction activity on or near military bases; a decline in nonresidential construction; a decline in energy-related drilling 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, or some combination thereof; a reduction in economic activity in the Company’s Midwest states resulting from reduced funding levels provided by the Agricultural Act of 2014 and a reduction in capital investment by the railroads; an increase in the cost of compliance with governmental laws and regulations; unexpected equipment failures, unscheduled maintenance, industrial accident or other prolonged and/or significant disruption to our cement production facilities; and the possibility that certain expected synergies and operating efficiencies in connection with the TXI acquisition are not realized within the expected time-frames or at all. 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 aggregates-related 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, help to mitigate the risk of uncollectible receivables. The level of aggregates demand in the Company’s end-use markets, production levels and the management of production costs will affect the operating leverage of the Aggregates business and, therefore, profitability. Production costs in the Aggregates business are also sensitive to energy and raw material prices, both directly and indirectly. Diesel fuel 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 Cement business is also energy intensive and fluctuations in the price of coal affects costs. The Magnesia Specialties business is sensitive to changes in domestic steel capacity utilization and the absolute price and fluctuations in the cost of natural gas.

Transportation in the Company’s long-haul network, particularly the supply of railcars and locomotive power and condition of rail infrastructure to move trains, affects the Company’s ability to efficiently transport aggregate into certain markets, most notably Texas, Florida and the Gulf Coast. In addition, availability of railcars and locomotives affects the Company’s ability to move dolomitic lime, a key raw material for magnesia chemicals, to both the Company’s plant in Manistee, Michigan, and customers. The availability of trucks, drivers and railcars to transport the Company’s product, particularly in markets experiencing high growth and increased demand, is also a risk and pressures the associated costs.

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

Risks to the outlook also include shipment declines as a result of economic events beyond the Company’s control. In addition to the impact on nonresidential and residential construction, the Company is exposed to risk in its estimated outlook from credit markets and the availability of and interest cost related to its debt.

The Company’s future performance is also exposed to risks from tax reform at the federal and state levels.

Non-GAAP Financial Measures

(Dollars in millions)

Gross margin as a percentage of net sales and operating margin as a percentage of net sales represent non-GAAP measures. The Company presents these ratios calculated based on net sales, as it is consistent with the basis by which management reviews the Company’s operating results. Further, management believes it is consistent with the basis by which investors analyze the Company’s operating results, given that freight and delivery revenues and costs represent pass-throughs and have no profit markup. Gross margin and operating margin calculated as percentages of total revenues represent the most directly comparable financial measures calculated in accordance with generally accepted accounting principles (“GAAP”). The following tables present the calculations of gross margin and operating margin for the three months ended March 31, 2015 and 2014, in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales:
