Record Second-Quarter Consolidated Revenues, Gross Profit and Earnings per Diluted Share

RALEIGH, N.C. (July 29, 2021) – Martin Marietta Materials, Inc. (NYSE: MLM) (“Martin Marietta” or the “Company”), a leading national supplier of aggregates and heavy building materials, today reported results for the second quarter ended June 30, 2021.

Ward Nye, Chairman and CEO of Martin Marietta, stated, “Our second-quarter results demonstrate Martin Marietta’s strong execution of our proven Strategic Operating Analysis and Review (SOAR) plan and the benefit of strengthening product demand, pricing gains across all product lines and targeted growth initiatives. The Company established new quarterly records for revenues, profits and safety, notwithstanding significant rainfall that adversely impacted operations in several of our key geographies, most notably Texas and Colorado, our two largest revenue states. Importantly, Martin Marietta is poised to capitalize on long-term secular demand trends that are expected to support growing construction activity and contribute to favorable pricing dynamics across our footprint. We remain on track to once again deliver record revenues and Adjusted EBITDA for the full year.

“As we responsibly and sustainably grow our business, we continue to advance SOAR 2025 and enhance our geographic footprint and product offerings. In May, we announced an agreement to acquire Lehigh Hanson, Inc.’s West Region business (“Lehigh West Region”), which provides the Company with a new upstream materials-led growth platform across several of the nation’s largest and fastest growing megaregions in California and Arizona. We expect the transaction to be accretive to earnings per diluted share in the first full year following closing, and are confident in our ability to quickly drive shareholder value using the time-tested integration approach we took with our River for the Rockies, TXI and Bluegrass acquisitions.”

Mr. Nye concluded, “As we SOAR to a Sustainable Future, Martin Marietta will continue to build on our foundation that has proven successful – an aggregates-led growth platform, a steadfast commitment to employee safety, disciplined pricing, operational excellence and solid execution of our strategy. We are confident in Martin Marietta’s outlook for the balance of the year and beyond and remain committed to delivering sustainable growth and superior shareholder value.”

Mr. Nye’s CEO Commentary and Market Perspective can be found on the Investors section of the Company’s website.

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

The Building Materials business achieved products and services revenues of $1.2 billion, a 7.4 percent increase, and product gross profit of $356.9 million.

The Building Materials business benefitted from solid product demand driven by single-family housing growth, infrastructure investment and notable heavy industrial projects of scale. The aggregates, cement and ready mixed concrete operations in Texas experienced project delays as the state marked its eleventh-wettest second quarter in 127 years. Additionally, the aggregates and downstream operations in Colorado faced a difficult comparison versus second-quarter 2020, which benefitted from unseasonably favorable weather conditions.

As previously announced, the Company completed the acquisition of Minnesota-based Tiller Corporation (“Tiller”) on April 30, 2021. Tiller’s aggregates and asphalt operations are reported as part of the East Group.

Second-quarter organic aggregates shipments and pricing increased 1.5 percent and 3.4 percent, respectively. Total aggregates shipments and pricing increased 3.3 percent and 2.9 percent, respectively.

Second-quarter aggregates product gross margin decreased 150 basis points to 34.0 percent, driven by higher diesel costs and a $6.1 million increase in cost of revenues from the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting. Excluding the impact of acquisition accounting, adjusted aggregates product gross margin was 34.8 percent.

Cement shipments decreased 1.9 percent, despite robust demand and construction activity throughout the Texas Triangle, resulting from extreme precipitation from late April through mid-June. Pricing improved 6.8 percent, or 4.2 percent on a mix-adjusted basis, following annual price increases that went into effect on April 1, 2021.

Cement product gross margin declined 870 basis points to 31.0 percent, driven by the timing of planned outages at the Company’s Hunter plant as well as higher energy and raw materials costs that more than offset pricing gains.

Ready mixed concrete shipments increased 8.2 percent, or 2.3 percent organically, as incremental volume from large projects and operations acquired in August 2020 more than offset weather headwinds. Pricing increased 1.2 percent, reflecting geographic mix from a lower percentage of higher-priced Colorado shipments. Product gross margin decreased 350 basis points to 7.1 percent, driven primarily by higher raw material and diesel costs.

Asphalt shipments increased 67.6 percent as incremental volume from the acquired Tiller operations more than offset weather-related shipment declines in Colorado. Additionally, pricing increased 4.9 percent. Asphalt and paving products and services gross margin improved 80 basis points, driven in part by the Tiller business.

Magnesia Specialties second-quarter product revenues increased 43.2 percent to $70.0 million versus a COVID-19-challenged prior-year quarter. Higher revenues, combined with disciplined cost control, resulted in product gross margin of 39.9 percent, a 260-basis-point improvement.

Second-quarter 2021 other operating income, net, included a $12.3 million nonrecurring gain on the sale of property.

Cash provided by operating activities for the six months ended June 30, 2021 was $441.2 million compared with $373.2 million for the prior-year period.

Cash paid for property, plant and equipment additions for the six months ended June 30, 2021 was $213.0 million. For the full-year, capital expenditures are expected to range from $450 million to $500 million.

Through dividend payments and share repurchases, the Company returned $71.8 million to shareholders in the first six months of 2021 and $1.9 billion since announcing a 20 million share repurchase authorization in February 2015.

The Company had $70.3 million of cash, cash equivalents and restricted cash on hand and $857.4 million of unused borrowing capacity on its existing credit facilities as of June 30, 2021.

In July 2021, the Company issued $2.5 billion of debt in anticipation of closing the Lehigh West Region acquisition in the second half of 2021. The acquisition remains subject to customary closing conditions. The newly-issued debt reflects a weighted-average interest rate of 2.2 percent.

Martin Marietta remains confident that favorable pricing dynamics will continue, supported by the Company’s locally-driven pricing strategy. Additionally, the Company anticipates single-family housing growth, expanded infrastructure investment and notable heavy industrial projects of scale will drive increased shipment levels. Martin Marietta expects these demand drivers, combined with the ancillary construction necessary for housing community buildouts and the potential for increased infrastructure investment from a comprehensive federal surface transportation package, to result in sustained, multi-year growth in product demand.

The Company has updated its full-year 2021 guidance to reflect recent trends and the contribution of the Tiller acquisition. This guidance excludes any benefit from additional fiscal stimulus, relief funds beyond those already enacted or a potential successor federal surface transportation bill.

Investors are cautioned that all statements in this release that relate to the future 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. These statements, which are forward-looking statements under the Private Securities Litigation Reform Act of 1995, give the investor the Company’s expectations or forecasts

of future events. You can identify these statements by the fact that they do not relate only to historical or current facts. They may use words such as “guidance”, “anticipate”, “expect”, “should”, “believe”, “will”, and other words of similar meaning in connection with future events or future operating or financial performance. Any or all of our forward-looking statements here and in other publications may turn out to be wrong.

Second-quarter results and trends described in this release may not necessarily be indicative of the Company’s future performance. The Company’s outlook is subject to various risks and uncertainties, and is based on assumptions that the Company believes in good faith are reasonable but which may be materially different from actual results. Factors that the Company currently believes could cause actual results to differ materially from the forward-looking statements in this release (including the outlook) include, but are not limited to: the ability of the Company to face challenges, including those posed by the COVID-19 pandemic and implementation of any such related response plans; the fluctuations in COVID-19 cases in the United States and the extent that geography of outbreak primarily matches the regions in which the Company’s Building Materials business principally operates; the resiliency and potential declines of the Company’s various construction end-use markets; the potential negative impact of the COVID-19 pandemic on the Company’s ability to continue supplying heavy-side building materials and related services at normal levels or at all in the Company’s key regions; the duration, impact and severity of the impacts of the COVID-19 pandemic on the Company, including the markets in which we do business, our suppliers, customers or other business partners as well as on our employees; the economic impact of government responses to the pandemic; the performance of the United States economy, including the impact on the economy of the COVID-19 pandemic and governmental orders restricting activities imposed to prevent further outbreak of COVID-19; shipment declines resulting from economic events beyond the Company’s control; a widespread decline in aggregates pricing, including a decline in aggregates shipment volume negatively affecting aggregates price; the history of both cement and ready mixed concrete being subject to significant changes in supply, demand and price fluctuations; the termination, capping and/or reduction or suspension of the federal and/or state gasoline tax(es) or other revenue related to public construction; the level and timing of federal, state or local transportation or infrastructure or public projects funding, most particularly in Texas, Colorado, North Carolina, Georgia, Florida, Iowa, Minnesota and Maryland; the impact of governmental orders restricting activities imposed to prevent further outbreak of COVID-19 on travel, potentially reducing state fuel tax revenues used to fund highway projects; the United States Congress’ inability to reach agreement among themselves or with the Administration on policy issues that impact the federal budget; the ability of states and/or other entities to finance approved projects either with tax revenues or alternative financing structures; levels of construction spending in the markets the Company serves; a reduction in defense spending and the subsequent impact on construction activity on or near military bases; a decline in the commercial component of the nonresidential construction market, notably office and retail space, including a decline resulting from economic distress related to the COVID-19 pandemic; a decline in energy-related construction activity resulting from a sustained period of low global oil prices or changes in oil production patterns or capital spending, particularly in Texas and West Virginia; increasing residential mortgage interest rates and other factors that could result in a slowdown in residential construction; unfavorable weather conditions, particularly Atlantic Ocean and Gulf of Mexico hurricane activity, the late start to spring or the early onset of winter and the impact of a drought or excessive rainfall in the markets served by the Company, any of which can significantly affect production schedules, volumes, product and/or geographic mix and profitability; whether the Company’s operations will continue to be treated as “essential” operations under applicable government orders restricting business activities imposed to prevent further outbreak of COVID-19 or, even if so treated, whether site-specific health and safety concerns might otherwise require certain of the Company’s operations to be halted for some period of time; the volatility of fuel costs, particularly diesel fuel, and the impact on the cost, or the availability generally, of other consumables, namely steel, explosives, tires and conveyor belts, and with respect to the Company’s Magnesia Specialties business, natural gas; continued increases in the cost of other repair and supply parts; construction labor shortages and/or supply‐chain challenges; unexpected equipment failures, unscheduled maintenance, industrial accident or other prolonged and/or significant disruption to production facilities; increasing governmental regulation, including environmental laws; the failure of relevant government agencies to implement expected regulatory reductions; transportation availability or a sustained reduction in capital investment by the railroads, notably the availability of railcars, locomotive power and the condition of rail infrastructure to move trains to supply the Company’s Texas, Colorado, Florida, Carolinas and Gulf Coast markets, including the movement of essential dolomitic lime for magnesia chemicals to the Company’s plant in Manistee, Michigan and its customers; increased transportation costs, including increases from higher or fluctuating passed-through energy costs or fuel surcharges, and other costs to comply with tightening regulations, as well as higher volumes of rail and water shipments; availability of trucks and licensed drivers for transport of the Company’s materials; availability and cost of construction equipment in the United States; weakening in the steel industry markets served by the Company’s dolomitic lime products; trade disputes 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 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; the possibility of a reduction of the Company’s credit rating to non-investment grade; and other risk factors listed from time to time found in the Company’s filings with the SEC.

You should consider these forward-looking statements in light of risk factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2020 and other periodic filings made with the SEC. All of our forward-looking statements should be considered in light of these factors.

Earnings before interest; income taxes; depreciation, depletion and amortization expense; the earnings/loss from nonconsolidated equity affiliates; acquisition-related expenses; and the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting (Adjusted EBITDA) is an indicator used by the Company and investors to evaluate the Company’s operating performance from period to period. Adjusted EBITDA is not defined by generally accepted accounting principles and, as such, should not be construed as an alternative to earnings from operations, net earnings or operating cash flow. For further information on Adjusted EBITDA, refer to the Company’s website at www.martinmarietta.com.

A Reconciliation of the GAAP Measure to 2021 Adjusted EBITDA Guidance Range is as follows:

Adjusted gross profit and adjusted gross margin represent non-GAAP financial measures and exclude the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting. Management presents these measures for investors and analysts to evaluate and forecast the Company’s results, as the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting is nonrecurring.

Adjusted earnings from operations and adjusted earnings per diluted share represent non-GAAP financial measures and exclude acquisition-related expenses and the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting. Management presents these measures for investors and analysts to evaluate and forecast the Company’s results, as the impact of acquisition-related expenses and selling acquired inventory after its markup to fair value as part of acquisition accounting are nonrecurring.

Mix-adjusted average selling price (mix-adjusted ASP) is a non-GAAP measure that excludes the impact of period-over-period product, geographic and other mix on the average selling price. Mix-adjusted ASP is calculated by comparing current-period shipments to like-for-like shipments in the comparable prior period. Management uses this metric to evaluate the realization of pricing increases and believes this information is useful to investors. The following reconciles reported average selling price to mix-adjusted ASP and corresponding variances.
