Ward Nye, Chairman, President and CEO of Martin Marietta, stated, “Our record-setting second-quarter results, which were driven by increased shipments, pricing improvements and growth initiatives, extend Martin Marietta’s lengthy track record of operational excellence, disciplined execution of our strategic plan and shareholder value creation. Underlying product demand and customer backlogs remain strong across our markets, with notable growth in Texas, North Carolina, Georgia and Iowa. In addition, our cement operations benefitted from the combination of strong demand and a tight supply environment, resulting in double-digit volume growth and a 680-basis-point improvement in product gross margin for the quarter.

“We are also pleased with the performance of our acquired Bluegrass Materials (Bluegrass) operations, which contributed $42 million in product revenues at anticipated margins comparable to our Mid-Atlantic and Southeast operations. This strategic acquisition is accretive to our shareholders and positions us to meaningfully enhance future performance as the eastern United States recovers from below mid-cycle aggregates demand. We are also on track to achieve our stated synergies. Additionally, in the second half of June, we enhanced the scale of our Midwest business by acquiring several Omaha, Nebraska-based sand and gravel operations and a permitted greenfield site, adding approximately 30 million tons of aggregates reserves. These value-enhancing transactions demonstrate our ability to prudently deploy capital to drive significant value for our shareholders, customers and other stakeholders.”

Mr. Nye concluded, “We believe the United States is in the midst of a construction recovery that will continue through the remainder of 2018 and beyond. Consistent with our forecasts at the beginning of the year, we expect construction activity to accelerate during the second half of this year, with faster growth in our key geographies due to these regions’ attractive economic drivers and population trends. We remain confident about Martin Marietta’s near-and long-term growth trajectory and expect 2018 to be another record year, as evidenced by our decision to raise our 2018 EBITDA guidance. We expect the disciplined execution of our strategic plan will continue to create shareholder value as we elevate Martin Marietta from an aggregates industry leader to a globally recognized world-class organization.”

Building Materials Business

Aggregates

During the quarter, aggregates shipments to the Company’s three primary end-use markets increased, demonstrating the breadth of the overall construction recovery. However, the limited availability of transportation and tight contractor labor markets pose challenges for more efficient throughput. Specifically, suboptimal railroad performance, limited truck availability and contractor capacity limitations, including their notable employee shortages, muted the Company’s overall second-quarter volume growth. That said, as capital and increased wages flow into the construction sector, the Company expects these temporary bottlenecks will abate, allowing supply and demand to reach equilibrium.

Inclusive of acquired operations, aggregates product revenues increased 15.1 percent for the quarter, reflecting volume growth of 11.3 percent and pricing growth of 3.5 percent. Heritage volume and pricing improved 3.4 percent and 4.4 percent, respectively.

| ♦ | Shipments for the Mid-America Group heritage operations increased 4.6 percent, driven by several large public and private construction projects in North Carolina. These operations generated heritage pricing gains of 6.3 percent, driven by continued price discipline.

| ♦ | Shipments for the Southeast Group heritage operations increased 3.4 percent, driven by strong construction activity in North Georgia. Weather and railroad inefficiencies hindered long-haul shipments from South Georgia to distribution yards in Florida, negatively affecting shipments and limited pricing growth to 1.5 percent.

| ♦ | West Group shipments improved 2.0 percent. Notably, all districts in the Southwest Division posted volume growth; however, this growth was partially offset by reduced Colorado volumes resulting from project delays and lower ballast sales. West Group pricing improved 3.2 percent, reflecting robust pricing in Colorado that was offset by product mix and a lower percentage of commercial rail-shipped volumes in Texas.

Martin Marietta’s second-quarter heritage aggregates shipments by end use are as follows (a ll comparisons are versus the prior-year quarter on a heritage basis):

Infrastructure Market

| ♦ | Aggregates shipments to the infrastructure market increased 2 percent, driven by large public projects in North Carolina and partially offset by project delays in Texas and Colorado as well as the previously-noted poor railroad service in Texas, South Georgia and Florida. The Company is encouraged by the recent acceleration of state lettings and contract awards; however, some contractors are reporting a longer lag time between contract awards and the commencement of projects. As state Departments of Transportation (DOTs) and contractors address labor constraints and the broader industry benefits from further regulatory reform, management remains confident that infrastructure demand will continue to improve from the funding provided by the Fixing America’s Surface Transportation Act (FAST Act) and numerous state and local transportation initiatives. Notably, once awarded, public construction projects are typically certain to be fully completed; thus, delays from weather or other factors merely extend the duration of the construction cycle for the Company’s single largest end use. Overall, aggregates shipments to the infrastructure market comprised 40 percent of second-quarter aggregates volumes, which remains below the Company’s most recent five-year average of 43 percent.

- MORE -

Nonresidential Market

| ♦ | Aggregates shipments to the nonresidential market increased 6 percent, driven by both commercial and heavy industrial construction activity. Additionally, ongoing energy-sector project approvals, supported by higher oil prices, underpin management’s expectation that the next wave of these large projects, particularly along the Gulf Coast, will contribute to increased aggregates demand for the next several years. The nonresidential market represented 33 percent of second-quarter aggregates shipments.

Residential Market

| ♦ | Aggregates shipments to the residential market increased 11 percent. Six of the Company’s key states - Texas, Florida, North Carolina, Colorado, Georgia and South Carolina - rank in the top ten nationally for growth in single-family housing unit starts for the trailing twelve months ended May 2018. The residential construction outlook across the Company’s geographic footprint remains positive for both single- and multi-family housing, driven by favorable demographics, job growth, land availability and efficient permitting. The residential market accounted for 22 percent of second-quarter aggregates shipments.

ChemRock/Rail Market

| ♦ | The ChemRock/Rail market accounted for the remaining 5 percent of second-quarter aggregates shipments. Shipments to this sector declined 21 percent reflective of the timing of certain purchases by East Coast railroads in the prior-year quarter as well as reduced ballast shipments due to lower maintenance spending by Class I railroads.

Aggregates product gross margin was 29.8 percent, inclusive of a $10.2 million negative impact on cost of sales related to selling acquired inventory that was marked up to fair value as part of acquisition accounting. Excluding this impact, adjusted aggregates product gross margin was 31.4 percent, an improvement of 150 basis points over the prior-year quarter.

Cement

Second-quarter cement product revenues increased 14.4 percent and gross profit increased 40.6 percent. Shipments and pricing improved 11.6 percent and 2.6 percent, respectively, reflecting the strong underlying market conditions throughout Texas. These factors, coupled with increased production efficiencies, led to a product gross margin of 36.5 percent.

Downstream businesses

Ready mixed concrete shipments increased 15.0 percent, driven primarily by strong construction activity in Texas, particularly in the Dallas/Fort Worth market. Overall, second-quarter ready mixed concrete prices decreased slightly, with lower energy-sector shipments and product mix in Texas offsetting the solid pricing gains in Dallas/Fort Worth and the nearly 6.0 percent pricing growth in Colorado. Project delays contributed to the 6.0 percent decrease in hot mixed asphalt shipments, while rising raw material costs allowed for favorable pricing during the quarter.

Magnesia Specialties Business

Magnesia Specialties product revenues increased 3.7 percent to a record $68.2 million with growth in both the chemicals and lime businesses. Higher costs for energy and contract services contributed to a 120-basis-point reduction of second-quarter product gross margin to 36.5 percent.

Consolidated

Other operating income, net, includes $16.9 million of gains on the sale of surplus land and $7.7 million, net, of litigation and related settlements.

During the quarter, Martin Marietta divested its heritage Forsyth aggregates quarry north of Atlanta, Georgia, and the legacy Bluegrass Beaver Creek aggregates quarry in western Maryland pursuant to the Company’s agreement with the United States Department of Justice to obtain regulatory approval for the Bluegrass acquisition. The gain on the Forsyth quarry divestiture is included in acquisition-related expenses, net, on the consolidated statements of earnings, and there was no gain or loss on the Beaver Creek divestiture. Excluding acquisition-related expenses, net, and the negative impact on cost of sales related to selling acquired inventory that was marked up to fair value as part of acquisition accounting, adjusted earnings from operations were $286.2 million, a 33.2 percent improvement from the prior-year quarter

Liquidity and Capital Resources

Cash provided by operating activities for the six months ended June 30 was $238.0 million in 2018 compared with $229.3 million in 2017.

Cash paid for property, plant and equipment additions for the six months ended June 30, 2018 was $188.3 million. The Company expects capital expenditures for full-year 2018 to range from $450 million to $500 million as it continues to prudently deploy capital into the business.

At June 30, 2018, the Company’s ratio of consolidated net debt-to-consolidated EBITDA, as defined in the applicable credit agreement, for the trailing twelve months was 2.75 times. The Company expects to be within its target leverage ratio of 2.0X to 2.5X by the end of 2018.

Commitment to Enhance Long-Term Shareholder Value

Martin Marietta is dedicated to disciplined capital allocation that preserves its financial flexibility and further enhances shareholder value. The Company’s capital allocation priorities remain unchanged and include value-enhancing acquisitions that promote 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.

The Company has returned $1.3 billion to shareholders, in the form of dividend payments and share repurchases, since announcing a 20 million share repurchase authorization in February 2015. At June 30, 2018, 14.7 million shares remain under the current repurchase authorization and 63.0 million shares of Martin Marietta common stock were outstanding.

Outlook for 2018

Martin Marietta remains confident about its near-term and long-term outlooks given the disciplined execution of its strategic business plan and the underlying market fundamentals, including positive employment and population trends, across its geographic footprint. The Company expects growth in all three primary construction end-use markets as the current broad-based construction recovery continues on an extended basis. Notably:

| ♦ | Infrastructure construction activity should benefit from the funding provided by the FAST Act as state DOTs and contractors address labor constraints and the benefits of further regulatory reform emerges.

- MORE -

|  | Additionally, state and local initiatives that support infrastructure funding, including gas tax increases, bond programs and other ballot initiatives, continue to garner voter approval and will play an expanded role in public-sector activity. Third-party forecasts support increased infrastructure investment in the second half of 2018, particularly for aggregates-intensive highways and streets.

| ♦ | Nonresidential construction activity should increase in both the commercial and heavy industrial sectors for the next several years as supported by third-party forecasts. Management expects new energy-related projects, particularly along the Gulf Coast, will bid in 2018 with broader construction activity beginning in earnest in 2019 and beyond as regulatory permitting and final investment decisions are either made and/or approved.

| ♦ | Residential construction should be robust, particularly in key Martin Marietta markets, bolstered by positive employment and population trends, historically low levels of construction activity over the previous years, low mortgage rates and increased lot development. Residential housing starts of 1.2 million units for the trailing twelve months ended June 2018 remain well below the 50-year average of 1.5 million annual starts. Continued strength in residential construction supports future infrastructure and nonresidential activity.

2018 Guidance

Management has increased both the low end and the high end of its full-year 2018 adjusted EBITDA guidance range by $25.0 million to reflect current trends and expectations, including the other operating income, net, recognized during the second quarter.

Specifically:

| ♦ | Heritage aggregates average selling price is expected to increase in a range of 3 percent to 5 percent.

| ♦ | Heritage aggregates volume is expected to increase in a range of 4 percent to 6 percent and expected shipments by end-use market compared with 2017 levels are as follows:

| • | Infrastructure shipments to increase in the mid-single digits.

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

| • | Residential shipments to increase in the high-single digits.

| • | ChemRock/Rail shipments to decrease.

a trade dispute with one or more nations impacting the U.S. economy, including the impact of tariffs on the steel industry; unplanned changes in costs or realignment of customers that introduce volatility to earnings, including that of the Magnesia Specialties business that is running at capacity; proper functioning of information technology and automated operating systems to manage or support operations; inflation and its effect on both production and interest costs; the concentration of customers in construction markets and the increased risk of potential losses on customer receivables; the impact of the level of demand in the Company’s end-use markets, production levels and management of production costs on the operating leverage and therefore profitability of the Company; the possibility that the expected synergies from acquisitions (including the acquisition of Bluegrass) will not be realized or will not be realized within the expected time period, including achieving anticipated profitability to maintain compliance with the Company’s leverage ratio debt covenant; changes in tax laws, the interpretation of such laws and/or administrative practices that would increase the Company’s tax rate; violation of the Company’s debt covenant if price and/or volumes return to previous levels of instability; downward pressure on the Company’s common stock price and its impact on goodwill impairment evaluations; reduction of the Company’s credit rating to non-investment grade resulting from strategic acquisitions; and other risk factors listed from time to time found in the Company’s filings with the SEC. Other factors besides those listed here may also adversely affect the Company, and may be material to the Company. The Company assumes no obligation to update any such forward-looking statements.
