Ward Nye, Chairman and CEO of Martin Marietta, stated, “Our year is off to a remarkable start with record first-quarter results by nearly every measure including continued world-class safety incidence rates. The cumulative effects of our 2022 and January 1, 2023 pricing actions drove robust margin expansion despite continued inflationary pressure and modestly lower aggregates shipments. Importantly, we achieved a quarterly record for aggregates pricing growth and a 134 percent increase in aggregates gross profit per ton, highlighting our team’s steadfast execution of our value-over-volume commercial strategy.

“We continue to see solid near-term product demand reinforced by healthy customer backlogs across our coast-to-coast footprint, led by infrastructure and heavy nonresidential projects of scale. We expect recent legislation and the resulting enhanced level of public investment in these kinds of aggregates-intensive end-use projects to support continued strong demand for several years to come. While single-family residential construction has slowed, builder sentiment has improved in Martin Marietta geographies as the single-family housing shortage continues to drive a base level of demand in our key Sun Belt markets. We also expect to see an uptick in residential activity as mortgage rates stabilize over the next several months.

Mr. Nye concluded, “We are confident in our ability to continue to expand margins throughout the year and expect to deliver compelling full-year financial results more directionally in line with the high end of our previously announced 2023 guidance range, which we will revisit at mid-year. Moreover, Martin Marietta’s track record of success throughout various business cycles proves the resiliency and durability of our aggregates-led business model and our ability to successfully navigate a wide array of macroeconomic environments to consistently deliver superior value for shareholders.”

First-Quarter Financial and Operating Results

(All financial and operating results are for continuing operations and comparisons are versus the prior-year first quarter, unless otherwise noted)

Building Materials Business

The Building Materials business generated record first-quarter revenues of $1.27 billion, a 10.1 percent increase. Gross profit increased 99.4 percent to a first-quarter record of $275.9 million. Double-digit pricing gains, partially offset by continued inflationary pressure, resulted in gross margin improvement of 970 basis points.

Aggregates

First-quarter aggregates shipments decreased 0.8 percent, largely due to historically wet weather in California which was partially offset by mild weather and strong demand in the Southeast. Pricing increased 22.6 percent, or 12.8 percent sequentially, due to the cumulative effect of 2022 and January 1, 2023 pricing actions.

Aggregates gross profit increased 131.7 percent to a first-quarter record of $238.1 million. Similarly, gross margin expanded 1,250 basis points to a first-quarter record of 26.1 percent, as strong pricing growth more than offset modestly lower shipments and increased costs.

Cement

Despite continued robust demand, cement shipments decreased 6.8 percent to 1.0 million tons, primarily attributable to wet and cold weather in Texas. Pricing increased 32.2 percent in the first quarter, a record for Martin Marietta, aided by largely sold-out conditions and the compounding effect of price increases in 2022 and 2023.

Cement gross profit increased 75.4 percent to a first-quarter record of $47.1 million. Gross margin increased 860 basis points to 28.0 percent, as pricing gains more than offset lower shipments and higher raw materials and maintenance costs.

Downstream businesses

Ready mixed concrete revenues and gross profit declined 24.4 percent and 48.9 percent, respectively, driven largely by the divestiture of the Company’s Colorado and Central Texas ready mixed concrete businesses on April 1, 2022.

Asphalt and paving revenues increased 2.1 percent to $58.0 million and, consistent with the Company’s historical first-quarter trends, the business posted an overall loss of $20.5 million due to seasonal winter operational shutdowns in Minnesota.

Portfolio Optimization

On April 26, 2023, the Company terminated its agreement with CalPortland Company ("CalPortland") regarding the sale of the Company’s Tehachapi, California cement plant and related distribution terminals to CalPortland in light of the parties being unable to timely obtain the necessary approval by the U.S. Federal Trade Commission. The Company intends to explore the potential sale of Tehachapi to other buyers. On May 3, 2023, the Company divested its cement import operations in California. Since October 1, 2021, these cement businesses were classified as assets held for sale on the Company’s consolidated balance sheet; the associated financial results continue to be reported as discontinued operations on the consolidated statement of earnings.

Magnesia Specialties Business

Magnesia Specialties revenues increased 8.4 percent to a first-quarter record of $83.4 million, driven by higher pricing for all product lines. Gross profit declined 2.7 percent to $25.0 million as higher supplies and contract services costs adversely impacted the quarter.

Cash Generation, Capital Allocation and Liquidity

Cash provided by operating activities for the quarter ended March 31, 2023 was $160.5 million compared with $169.9 million for the prior-year period.

Cash paid for property, plant and equipment additions for the quarter ended March 31, 2023 was $173.9 million.

During the quarter ended March 31, 2023, the Company returned $116.6 million to shareholders through dividend payments and share repurchases. As of March 31, 2023, 12.9 million shares remained under the current repurchase authorization.

The Company had $229.4 million of unrestricted cash and cash equivalents on hand and $1.2 billion of unused borrowing capacity on its existing credit facilities as of March 31, 2023.

Non-GAAP Financial Information

This earnings release contains financial measures that have not been prepared in accordance with generally accepted accounting principles in the United States (GAAP). Reconciliations of non-GAAP financial measures to the closest GAAP measures are included in the Appendix to this earnings release. Management believes these non-GAAP measures are commonly used financial measures for investors to evaluate the Company’s operating performance and, when read in conjunction with the Company’s consolidated financial statements, present a useful tool to evaluate the Company’s ongoing operations, performance from period to period and anticipated performance. In addition, these are some of the factors the Company uses in internal evaluations of the overall performance of its businesses. Management acknowledges that there are many items that impact a company’s reported results and the adjustments reflected in these non-GAAP measures are not intended to present all items that may have impacted these results. In addition, these non-GAAP measures are not necessarily comparable to similarly titled measures used by other companies.

The Company will discuss its first-quarter 2023 earnings results on a conference call and an online webcast today (May 4, 2023). The live broadcast of the Martin Marietta conference call will begin at 10:00 a.m. Eastern Time and can be accessed here.

If you are interested in Martin Marietta stock, management recommends that, at a minimum, reading the Company’s current annual report and Forms 10-K, 10-Q and 8-K reports to the Securities and Exchange Commission (SEC) over the past year. The Company’s recent proxy statement for the annual meeting of shareholders also contains important information. These and other materials that have been filed with the SEC are accessible through the Company’s website at www.martinmarietta.com and are also available at the SEC’s website at www.sec.gov. You may also write or call the Company’s Corporate Secretary, who will provide copies of such reports.

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, provide the investor with 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”, “may”, “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 the Company’s forward-looking statements here and in other publications may turn out to be wrong.

First-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 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 fuel 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, California, North Carolina, Georgia, Minnesota, Iowa, Florida, Indiana and Arizona; 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 energy-related construction activity resulting from suspension of the fuel tax or 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, Pacific Ocean and Gulf of Mexico storm and hurricane activity, wildfires, 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; 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; the resiliency and potential declines of the Company’s various construction end-use markets; the potential negative impacts of global health crises such as COVID-19 and its variants; increasing governmental regulation, including environmental laws and climate change regulations; 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, including acquisitions or divestitures, 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 Martin Marietta’s Annual Report on Form 10-K for the year ended December 31, 2022 and other periodic filings made with the SEC. All of the Company’s forward-looking statements should be considered in light of these factors. In addition, other risks and uncertainties not presently known to the Company or that it considers immaterial could affect the accuracy of its forward-looking statements, or adversely affect or be material to the Company. The Company assumes no obligation to update any such forward-looking statements.

Non-GAAP Financial Measures

Earnings from continuing operations before interest; income taxes; depreciation, depletion and amortization expense; the earnings/loss from nonconsolidated equity affiliates; and acquisition and integration expenses (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 attributable to Martin Marietta or operating cash flow.

Non-GAAP Financial Measures (Continued)

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.
