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, “The first quarter was highlighted by numerous significant events that, taken together, should be very beneficial to the Company this year and into the future. Namely, Martin Marietta completed over $4.5 billion of portfolio-enhancing transactions thus far in 2024, increased our aggregates gross profit per ton by over 14 percent for the quarter, and achieved record quarterly gross profit in our Magnesia Specialties business - all notwithstanding the year's weather-challenged start in our most profitable markets. Collectively, these notable accomplishments give us confidence in our ability to increase our full-year 2024 Adjusted EBITDA guidance to $2.37 billion at the midpoint.

"Our positive outlook also reflects continued pricing momentum together with the product demand we expect from record federal- and state-level infrastructure investments, large-scale heavy industrial activity, data centers, and energy projects, which should counterbalance softer residential and warehouse construction demand, as well as an anticipated moderation in light nonresidential activity. Despite near-term interest rate uncertainty, single-family housing remains historically under built, particularly in key Martin Marietta markets with notable population growth. As such, we expect Martin Marietta will disproportionately benefit from new single-family home construction once interest rates moderate and affordability headwinds recede.

"Consistent with our SOAR 2025 priorities, we have continued to strengthen our portfolio by reducing cyclical downstream exposure, while expanding our aggregates footprint through the additions of the Albert Frei & Sons and Blue Water Industries operations. Combined, these pure-play aggregates transactions are expected to add approximately 17 million tons of annual shipments in key markets including Denver, Knoxville, Miami and Nashville, while enhancing our ability to generate consistently higher margins."

Mr. Nye concluded, "Martin Marietta's unrivaled growth opportunities, steady advancement of our strategic plan and fidelity to disciplined pricing and operational excellence, together with multi-year infrastructure tailwinds across our purposefully curated geographic footprint, underpins our confidence to continue delivering sustainable growth and superior value for shareholders for the foreseeable future."

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 revenues of $1.2 billion, an eight percent decrease. Gross profit decreased ten percent to $248 million.

Aggregates

First-quarter aggregates shipments decreased 12.3 percent to 36.6 million tons due largely to a more weather-impacted start to the year in the Company's East and Southwest Divisions coupled with softening demand in warehouse, office and retail construction, partially offset by more favorable weather and relative strength in the Company's Central and West Divisions. Average selling price (ASP) increased 12.2 percent to $22.26 per ton, or 12.7 percent on an organic mix-adjusted basis, due to strong realization of January 1, 2024, pricing actions.

Aggregates gross profit increased modestly to $239 million, as pricing growth more than offset lower shipments.

Cement and Downstream Businesses

Cement and ready mixed concrete revenues decreased 22 percent to $265 million and gross profit decreased 47 percent to $31 million compared with the prior-year quarter, primarily due to the February 2024 divestiture of the South Texas cement plant and related concrete operations, as well as extremely wet weather in Texas.

Asphalt and paving revenues increased one percent to a first-quarter record of $59 million. Consistent with the Company's historical first-quarter trends, the business posted a gross loss of $22 million due to seasonal winter operational shutdowns in Minnesota and unfavorable winter conditions in Colorado.

Magnesia Specialties Business

Magnesia Specialties achieved record first-quarter gross profit of $29 million, an increase of 15 percent, despite a three percent decrease in revenues to $81 million, as higher pricing offset lower chemical shipments.

Portfolio Optimization

Acquisitions

On January 12, 2024, the Company completed the acquisition of Albert Frei & Sons, Inc. (AFS), a leading aggregates producer in Colorado. On April 5, 2024, the Company completed the acquisition of 20 active aggregates operations in Alabama, South Carolina, South Florida, Tennessee and Virginia from Blue Water Industries LLC (BWI Southeast) for $2.05 billion in cash.

Divestitures

On February 9, 2024, the Company divested its South Texas cement and related concrete operations to CRH Americas Materials, Inc., a subsidiary of CRH plc, for $2.10 billion in cash.

Cash Generation, Capital Allocation and Liquidity

Cash provided by operating activities for the three months ended March 31, 2024, was $172 million compared with $161 million for the prior-year period.

Cash paid for property, plant and equipment additions for the three months ended March 31, 2024, was $200 million.

During the three months ended March 31, 2024, the Company returned $197 million to shareholders through dividend payments and share repurchases. As of March 31, 2024, 12.5 million shares remained under the current repurchase authorization.

The Company had $2.6 billion 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, 2024.

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 revised 2024 Guidance) include, but are not limited to: the ability of the Company to face challenges, including shipment declines resulting from economic and weather 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 from such federal and state budgets, most particularly in Texas, North Carolina, Colorado, California, Georgia, Minnesota, 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 have 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; 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; the strategic benefits, outlook, performance and opportunities expected as a result of acquisitions and portfolio optimization; 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; cybersecurity risks; 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.

MARTIN MARIETTA MATERIALS, INC.Non-GAAP Financial Measures

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.
