Gross profit	$	676.0	$	487.8	38.6	%
Earnings from operations	$	566.6	$	405.9	39.6	%

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, or Adjusted EBITDA, is a non-GAAP financial measure. See Appendix to this earnings release for a reconciliation to net earnings from continuing operations attributable to Martin Marietta.

Ward Nye, Chairman and CEO of Martin Marietta, stated, "We are pleased to again report record quarterly results for nearly every financial and operational measure, including continued world-class safety incidence rates. These extraordinary results demonstrate the earnings power of our business, driven by our team's disciplined execution of our proven value-over-volume commercial strategy. Our commitment to safety, enterprise excellence and the steady advancement of our strategic plan underpins our track record of success and our confidence to continue delivering attractive growth.

"Consistent with our aggregates-led product focus, on October 31, 2023, we closed the sale of our Tehachapi, California cement plant for $315 million, which largely concludes planned asset sales from the 2021 Lehigh Hanson West acquisition. This divestiture not only improves our product mix, but also provides additional balance sheet flexibility to redeploy the proceeds into pure-play aggregates acquisitions.

"The results for the quarter and through nine months underscore our confidence that Martin Marietta will continue to outperform in the near-, medium- and long-term as we benefit from our business-mix portfolio and carefully curated coast-to-coast footprint. Specifically, we see increased investment in large infrastructure and manufacturing projects across the United States. These positive trends provide an attractive counter-balance to the slowing in warehouses, private light nonresidential and residential construction, which have been impacted by tightening credit conditions. Notably however, the single-family residential sector, remains fundamentally underbuilt, particularly in key Martin Marietta Sun Belt markets. As such, we fully expect demand in these end markets to accelerate when inflation moderates and restrictive monetary policy eases."

Mr. Nye concluded, "Our outstanding year-to-date results, despite reduced product shipments, underscore the durability of our business, the vitality of our chosen geographies, the efficacy of our value-over-volume market approach, as well as our ability to adapt to the challenges inherent in the current volatile macroeconomic and geopolitical environment. With robust, multi-year demand from infrastructure and U.S.-based manufacturing, coupled with an attractive commercial environment, Martin Marietta is well-positioned to deliver compelling results and superior shareholder value for the foreseeable future."

Third-Quarter Financial and Operating Results

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

Building Materials Business

The Building Materials business generated record revenues of $1.9 billion, a 10.5 percent increase. Gross profit increased 38.4 percent to a record of $649.5 million.

Aggregates

Third-quarter aggregates shipments decreased 7.3 percent, as softer demand in certain Midwest and Southwest markets was partially offset by continued strength in key Southeast markets. Pricing increased 20.0 percent, or 17.2 percent on a mix-adjusted basis, due to the cumulative effect of January 1, 2023 and mid-year 2023 pricing actions.

Aggregates gross profit increased 32.1 percent to a record of $440.6 million as pricing growth more than offset lower shipments and higher costs, underscoring the benefits of the Company's value-over volume commercial philosophy.

Cement

Cement shipments of 1.1 million tons were relatively flat while pricing increased 18.9 percent, or 18.6 percent on a mix-adjusted basis, as largely sold-out conditions continue to drive robust pricing momentum.

Cement gross profit increased 61.5 percent to a record $108.7 million.

Downstream businesses

Ready mixed concrete revenues increased 25.3 percent to $285.2 million while gross profit increased 81.8 percent to $34.1 million.

Asphalt and paving revenues increased 14.6 percent to a record of $359.9 million. Likewise, gross profit increased 33.0 percent to a record of $66.1 million, as lower natural gas and liquid asphalt, or bitumen, costs augmented pricing growth.

Magnesia Specialties Business

Magnesia Specialties revenues of $75.5 million were flat as softer demand for chemical products was offset by strong pricing improvement in both chemicals and lime product lines. Gross profit increased 3.6 percent to $21.4 million, as energy cost moderation and higher pricing more than offset lower operating leverage.

Cash Generation, Capital Allocation and Liquidity

Cash provided by operating activities for the nine months ended September 30, 2023 was $972.5 million compared with $560.7 million for the prior-year period, reflecting the growth in net earnings.

Cash paid for property, plant and equipment additions for the nine months ended September 30, 2023 was $464.1 million.

During the nine months ended September 30, 2023, the Company returned $278.2 million to shareholders through dividend payments and share repurchases. As of September 30, 2023, 12.7 million shares remained under the current repurchase authorization.

The Company had $647.6 million of unrestricted cash and cash equivalents on hand and $1.20 billion of unused borrowing capacity on its existing credit facilities as of September 30, 2023.

1	Total revenues include the sales of products and services to customers (net of any discounts or allowances) and freight revenues.
2	Adjusted EBITDA is a non-GAAP financial measure. See Appendix to this earnings release for a reconciliation to net earnings from continuing operations attributable to Martin Marietta.
3	Volume change is for aggregates shipments, inclusive of internal tons, and is in comparison to 2022 shipments of 207.7 million tons.
4	ASP change is for aggregates average selling price and is in comparison to 2022 ASP of $16.68 per ton.

Preliminary View of 2024

Aggregates shipments are expected to be relatively flat, as strong demand from public infrastructure and heavy nonresidential projects of scale will partially offset an anticipated softening in the interest-rate sensitive, private light nonresidential and residential sectors. The Company anticipates low double-digit aggregates pricing growth as carryover effects from 2023 together with January 1, 2024 price increases will offset continued inflationary pressure from the recent acceleration in energy-related costs. Notably, the incremental benefits of any 2024 mid-year pricing actions are not included in this preliminary view.

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.

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 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.

Any or all of the Company's forward-looking statements here and in other publications may turn out to be wrong.

Third-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 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 and any issues arising from such federal and state budgets, most particularly in Texas, Colorado, North Carolina, Minnesota, California, Georgia, Arizona, Iowa, Florida and Indiana; the United States Congress' inability to reach agreement among themselves or with the Executive Branch 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 a sustained period of low global oil prices or changes in oil production patterns or capital spending in response to this decline, particularly in Texas and West Virginia; sustained high residential mortgage rates and other factors that has resulted in a slowdown in residential construction in some geographies; 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 and energy, particularly diesel fuel, electricity, natural gas 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 or societal response, including any impact on the Company's suppliers, customers or other business partners as well as on its employees; the performance of the United States economy; increasing governmental regulation, including environmental laws and climate change regulations at the federal and state levels; 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 the 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; potential impact on costs, supply chain, oil and gas prices, or other matters relating to the war between Russia and Ukraine, the war in Israel and related conflict in the Middle East and the conflict between China and Taiwan; 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.

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.
