Ward Nye, Chairman and CEO of Martin Marietta, stated, “Martin Marietta delivered exceptional performance across nearly every safety, financial and operational measure in the second quarter. These impressive results, despite lower aggregates shipments, demonstrate the success of our value-over-volume commercial strategy and the durability of our business model through various macroeconomic conditions. Our second-quarter results, together with our expectations for an even stronger next six months, underpin our revised full-year Adjusted EBITDA guidance range of $2.0 – $2.1 billion, a 28 percent increase at the midpoint as compared with the prior year.

“As record-setting public funds for infrastructure and manufacturing begin to enter the U.S. economy, we continue to expect that aggregates demand will accelerate in the second half of 2023. This well-chronicled increased investment should largely offset the current residential construction air pocket, which we expect to bottom in the third quarter of 2023.”

Mr. Nye concluded, “This scenario, combined with continued commercial momentum and moderating cost inflation, should contribute to a record-setting year in 2023 and provide a solid foundation for an even brighter 2024 and beyond. Our fidelity to safety, enterprise excellence, sustainable business practices and execution of our strategic plan reinforces our confidence in Martin Marietta’s ability to consistently deliver superior shareholder value.”

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

The Company is actively exploring the potential sale of Tehachapi to other interested parties. The Tehachapi cement business is classified within assets held for sale on the Company’s consolidated balance sheet and the associated financial results continue to be reported as discontinued operations on the consolidated statement of earnings.

Magnesia Specialties Business

Magnesia Specialties revenues were $80.5 million in the second quarter while gross profit increased 13.0 percent to $27.7 million due to pricing and a moderation of energy expenses.

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.

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.

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 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 and any issues arising with such federal and state budgets, 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 new waves of COVID-19 or its variants, or any other outbreak of disease, epidemic or pandemic, or similar public health threat, or fear of such event and its related economic and societal response; 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; acquisition and integration expenses; and the nonrecurring gain on divestiture (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. For further information on Adjusted EBITDA, refer to the Company’s website at www.martinmarietta.com.

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.

	Three Months Ended					Six Months Ended
	June 30,					June 30,
	2023			2022		2023			2022
