Ward Nye, Chairman, President and CEO of Martin Marietta, stated, “Building on our strong momentum in the first half of the year, we once again delivered exceptional performance, establishing new quarterly records for revenues, gross profit, adjusted EBITDA and earnings per diluted share. These record-setting third-quarter results, driven by broad-based improvements in shipments, pricing and profitability across the majority of our Building Materials business, reflect the disciplined execution of our strategic plan and our team’s unrelenting commitment to operational excellence. Based on recent trends and our solid performance to date, we are raising our outlook for the remainder of 2019.

“We have carefully positioned our business, geographically and otherwise, to capitalize on attractive market fundamentals that support sustainable and long-term construction growth, including employment gains, positive demographic trends and superior state fiscal health. Our third-quarter performance, including double-digit-growth in both aggregates and cement shipments, as well as solid volume growth in our downstream products, demonstrates Martin Marietta’s ability to take advantage of robust underlying demand and the meaningful acceleration of infrastructure construction projects in our key states. These favorable dynamics, combined with the benefits of our locally-driven pricing strategy, underscore the comparative strength of our markets and bode well for continued construction gains. With increased infrastructure activity as a result of state and local transportation funding initiatives, and continued private-sector strength, we are confident that construction activity in our Top 10 states will continue growing and outpacing the nation as a whole.”

Mr. Nye concluded, “In 25 years as a public company, Martin Marietta has thoughtfully developed and consistently executed on its strategic plans, positioning our business as an aggregates leader in attractive high-growth geographies, aligning our product offerings to leverage strategic cement and targeted downstream opportunities and responsibly allocating capital while maintaining financial flexibility. This steadfast and proven strategy, together with our commitment to the world-class attributes of our business – including, safety, ethics, cost discipline and operational excellence – underpins our confidence in Martin Marietta’s outlook for continued profitable growth and enhanced shareholder value creation.”

Building Materials Business

Third-quarter operating results demonstrate the strength and breadth of overall demand across the Company’s geographic footprint and product lines, notwithstanding the favorable comparison from a weather-challenged prior-year quarter. Aggregates, cement and downstream operations in Texas and Colorado, the Company’s two largest states by revenues, also benefited from weather-deferred projects from earlier in the year.


Third-quarter aggregates shipments and pricing improved 12.4 percent and 5.3 percent, respectively.

  • Shipments for the Mid-America Group operations increased 14.0 percent, reflecting attractive market fundamentals that have bolstered continued infrastructure and commercial construction activity. Pricing improved 3.5 percent. 
  • Shipments for the Southeast Group operations increased 0.8 percent following double-digit-growth in the prior-year quarter. Volume growth was muted by the impact of Hurricane Dorian, as well as the delayed timing of projects in the region. Pricing improved 5.7 percent, reflecting the strength of the North Georgia and Florida markets.
  • West Group shipments increased 14.8 percent, driven by energy-related projects along the Gulf Coast, increasing commercial activity in Colorado, and improved weather that allowed customers to advance weather-deferred projects. Pricing growth of 9.2 percent reflected favorable geographic and product mix.

Martin Marietta’s third-quarter aggregates shipments by end use are as follows (all comparisons are versus the prior-year quarter)

Infrastructure Market

  • Aggregates shipments to the infrastructure market increased 7 percent. As expected, transportation-related projects accelerated during the quarter, supported by funding provided by the Fixing America’s Surface Transportation Act (FAST Act) and numerous state and local transportation initiatives and continued reconstruction efforts following flooding in the Midwest. For the quarter, the infrastructure market represented 38 percent of aggregates shipments, which is below the Company’s most recent ten-year average of 46 percent.

Nonresidential Market

  • Aggregates shipments to the nonresidential market increased 19 percent, driven by gains in commercial and heavy industrial construction activity. The Company continued to benefit from distribution center, warehouse, data center and wind energy projects in key geographies, including Texas, the Carolinas, Iowa and Maryland, as well as the early phases of several large energy-sector projects along the Gulf Coast. The nonresidential market represented 34 percent of third-quarter aggregates shipments.     

Residential Market

  • Aggregates shipments to the residential market increased 16 percent, driven by continued homebuilding activity in states such as Texas, Colorado, the Carolinas, Georgia and Florida. 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, low interest rates and efficient permitting. On a national level, housing starts remain below the 50-year annual average of 1.5 million despite notable population gains. The residential market accounted for 22 percent of third-quarter aggregates shipments.

ChemRock/Rail Market

  • The ChemRock/Rail market accounted for the remaining 6 percent of third-quarter aggregates shipments. Volumes to this end use increased 4 percent, driven by improved ballast shipments as the western Class 1 railroads continued to address repairs from the Midwest flooding earlier in the year.

Aggregates product gross margin expanded 480 basis points to 35.1 percent, reflecting pricing gains, improved operating leverage from increased shipment and production levels and the absence of the $8.3 million negative impact of selling acquired inventory after its markup to fair value as part of acquisition accounting incurred in 2018 as part of the Company’s purchase of Bluegrass Materials. 


Third-quarter cement shipments increased 20.6 percent, driven by strong underlying Texas demand and weather-deferred projects from second-quarter 2019. Unfavorable product mix constrained pricing growth to 1.6 percent. Production efficiencies from increased shipment and production levels, coupled with lower maintenance costs, contributed to the 750-basis-point improvement in product gross margin to 40.6 percent. 

Downstream businesses

Ready mixed concrete shipments increased 9.0 percent and benefitted from healthy demand environments in Texas and Colorado and weather-impacted carryover projects. Ready mixed concrete selling prices declined 2.2 percent, reflecting unfavorable product mix.  Colorado asphalt shipments increased 34.1 percent while pricing improved 3.3 percent. 

Magnesia Specialties Business

Magnesia Specialties product revenues decreased 13.2 percent to $59.3 million as international chemicals and domestic lime customers rationalized inventory levels.  Despite lower revenues, product gross margin improved 120 basis points to 40.4 percent driven by lower costs for contract services and supplies and enhanced cost control measures.


Other operating expenses, net, for the prior-year quarter included a $7.1 million asset and portfolio rationalization charge related to the Company’s Southwest ready mixed concrete business.

Liquidity and Capital Resources

Cash provided by operating activities for the nine months ended September 30 was $649.8 million in 2019 compared with $441.5 million in 2018, driven by growth in earnings before noncash expenses and lower contributions to the Company’s pension plan partially offset by higher working capital related to increased revenues.

Cash paid for property, plant and equipment additions for the nine months ended September 30, 2019 was $283.0 million. The Company expects capital expenditures to range from $375 million to $400 million for the full year.

At September 30, 2019, the Company’s ratio of consolidated net debt-to-consolidated EBITDA, as defined in the applicable credit agreement, for the trailing twelve months was 2.3 times. 

Commitment to Enhance Long-Term Shareholder Value

Martin Marietta is dedicated to disciplined capital allocation that preserves the Company’s 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 meaningful and sustainable dividends and share repurchases.

The Company has returned $1.5 billion to shareholders in the form of dividend payments and share repurchases since announcing a 20 million share repurchase authorization in February 2015. In August 2019, the Board of Directors approved a 15-percent-increase in the quarterly cash dividend, one of the largest increases in the Company’s history. Additionally, during third-quarter 2019, the Company repurchased 29,200 shares of common stock pursuant to its share repurchase authorization.  As of September 30, 2019, 13.9 million shares remained under the current repurchase authorization and 62.5 million shares of Martin Marietta common stock were outstanding.

Full-Year 2019 Outlook

Based on current trends and expectations, management has raised its full-year 2019 guidance. Specifically: 

  • Aggregates shipments by end-use market compared with 2018 levels are as follows:
    • Infrastructure shipments to increase in the high-single digits.
    • Nonresidential shipments to experience a double-digit increase.
    • Residential shipments to experience a double-digit increase.
    • ChemRock/Rail shipments to be up slightly.

Preliminary View of 2020

Based on a preliminary view of 2020, management currently anticipates low-to-mid-single-digit growth in aggregates shipments and mid-single-digit growth in aggregates pricing. Martin Marietta’s geographic footprint has attractive underlying market fundamentals, including notable employment gains, population growth and superior state fiscal health, that should promote steady and sustainable construction growth over the near- and medium-terms. Supported by region-specific third-party forecasts and underlying demand trends, Martin Marietta believes the current construction cycle will continue for the foreseeable future and expand at a steady pace in 2020 for each of its three primary construction end-use markets. Notably:

  • Infrastructure construction, particularly for aggregates-intensive highways and streets, should continue to benefit from the acceleration in state lettings and contract awards in key Martin Marietta states, continued FAST Act funding, and regulatory reform that allows for reduced permitting time for large projects. Management believes that federal transportation funding will continue, at a minimum, at status quo levels absent the prospective passage of a successor infrastructure bill prior to the FAST Act’s September 2020 expiration. This should provide the necessary confidence and visibility for states to continue to advance planned and future construction projects. Importantly, states will continue to play an expanded role in infrastructure investment. Incremental funding at the state and local levels, through bond issuances, toll roads and tax initiatives, should grow at faster near-term rates than federal funding. Martin Marietta’s top ten states – Texas, Colorado, North Carolina, Georgia, Iowa, Florida, South Carolina, Indiana, Maryland and Nebraska – accounted for 85 percent of total Building Materials’ revenues in 2018 and have all introduced incremental transportation funding measures within the last five years. Third-party forecasts also predict increased infrastructure investment in 2020 and beyond.

  • Nonresidential construction should increase in both the commercial and heavy industrial sectors for the next several years across many of the Company’s key markets. While the national Architectural Billings and Dodge Momentum Indices have moved modestly in 2019, management believes continued employment growth will provide the impetus for sustainable commercial construction activity. Continued federal regulatory approvals should contribute to increased heavy building materials consumption from the next wave of large energy-sector projects, particularly along the Gulf Coast. Construction activity for these projects is expected to continue for several years. 

  • Residential construction should continue to grow within Martin Marietta’s geographic footprint, particularly as mortgage rates remain attractive and homebuilders address the need for more affordable homes. The Company’s leading positions in southeastern and southwestern states offer superior opportunities, such as available land, an overall business-friendly environment and fewer regulatory barriers, for gains in both multi- and single-family housing. The Company believes that permits represent the best indicator of future housing construction. Martin Marietta’s top ten states significantly outpaced the nation in housing unit permit growth for the trailing twelve months ended September 2019 for both multi-family and single-family. Continued strength in residential construction supports future infrastructure and nonresidential activity.
