Ward Nye, Chairman and CEO of Martin Marietta, stated, "2022 marked our Company's eleventh consecutive year delivering increased products and services revenues, gross profit and Adjusted EBITDA, as well as our most profitable year ever. We achieved record financial results and world-class safety incidence rates while also seamlessly integrating a large platform acquisition and completing non-core asset divestitures against a backdrop of rapid monetary tightening, a resulting housing slowdown, and cost inflation at 40-year highs. These accomplishments are a testament to our team's disciplined execution of our strategic plan and unyielding focus on what we can control. Moreover, in a notably weather-impacted fourth quarter, our team nonetheless expanded aggregates margins and increased gross profit per shipped ton by 25 percent over the prior-year quarter. These successes were underscored by an all-time quarterly record of aggregates pricing growth and position our Company well to deliver another record year in 2023.

"Entering 2023, near-term product demand visibility is supported by healthy customer backlogs driven by an acceleration in public infrastructure investment and announced large-scale energy and domestic manufacturing projects. While single-family residential construction is slowing, we expect a resumption of growth in this end market in Martin Marietta markets beyond 2023 as population growth continues and mortgage rates stabilize. In total, we expect full year 2023 aggregates shipments to be relatively flat but, given the carryover effects of our 2022 commercial actions and broad acceptance of our January 1, 2023 price increases, we are confident in our ability to continue to deliver accelerated margin expansion.

Mr. Nye concluded, "Our resilient and durable business model gives us the confidence in our ability to continue our industry-leading operational, financial and regulatory performance while successfully navigating the dynamic macroeconomic environment and sustainably delivering value for shareholders."

Fourth-Quarter Financial and Operating Results

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

Building Materials Business

The Building Materials business generated products and services revenues of $1.31 billion for the fourth quarter, a 1.7 percent decrease, attributable to colder temperatures and increased precipitation across most of the Company's geographies. However, products and services gross profit increased 4.0 percent to a fourth-quarter record of $331.1 million. Products and services gross margin improved 140 basis points to 25.2 percent as the effect of multiple price increases during the year more than offset higher operating costs and lower, weather-impacted, shipments.

Aggregates

Fourth-quarter aggregates shipments decreased 12.0 percent, largely due to inclement weather in a number of key markets compared to the unseasonably warm and dry prior-year period that extended 2021 construction activity. Pricing increased 16.5 percent, a quarterly record, or 13.8 percent on a mix-adjusted basis, due to the cumulative effect of multiple price increases throughout the year.

Fourth-quarter aggregates product gross profit improved 10.1 percent to a fourth-quarter record of $239.0 million. Similarly, product gross margin improved 200 basis points to 28.2 percent, as robust pricing growth more than offset lower shipments and increased costs.

Cement

Despite robust product demand, fourth quarter cement shipments decreased 10.8 percent to 0.9 million tons, primarily attributable to wet and cold weather in Texas. Pricing increased 20.8 percent, aided by largely sold-out conditions and the compounding effect of the year's multiple price increases. Cement product gross profit grew 4.4 percent to a fourth-quarter record of $58.2 million. Product gross margin declined 140 basis points to 39.6 percent, as pricing gains were not enough to offset the impacts of lower operating leverage and higher energy, raw materials and maintenance costs in the period.

Downstream businesses

Ready mixed concrete product revenues and product gross profit declined 35.4 percent and 39.9 percent, respectively, driven largely by the April 1 divestiture of the Company's Colorado and Central Texas ready mixed concrete businesses, impacting comparability with the prior year. Increased raw materials costs for aggregates and cement weighed on product gross profit and product gross margin.

Asphalt and paving product and services revenues increased 16.3 percent to $198.6 million while product and services gross profit decreased 6.9 percent to $18.4 million as price increases did not fully offset raw material cost increases.

Magnesia Specialties Business

Magnesia Specialties product revenues decreased 6.0 percent to $63.5 million, driven by lower demand for chemical and lime products. Product gross profit declined 18.0 percent to $21.3 million as lower volumes and higher energy and maintenance costs adversely impacted the fourth quarter.

Cash Generation, Capital Allocation and Liquidity

Cash provided by operating activities for the year ended December 31, 2022 was $991.2 million compared with $1.14 billion for the prior-year period.

Cash paid for property, plant and equipment additions for the year ended December 31, 2022 was $481.8 million.

During the year ended December 31, 2022, the Company returned $309.1 million to shareholders through dividend payments and share repurchases. As of December 31, 2022, 13.1 million shares remained under the current repurchase authorization.

The Company had $358.0 million of unrestricted cash and cash equivalents on hand and $1.2 billion of unused borrowing capacity on its existing credit facilities as of December 31, 2022.

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.

Fourth-quarter and full-year 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, notably related to the current conflict between Russia and Ukraine, 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, 2021, Martin Marietta's Quarterly Reports on Form 10-Q for the quarters ended March 31, 2022, June 30, 2022 and September 30, 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.

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-related expenses; the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting; and the nonrecurring gain on the divestiture of certain ready mixed concrete operations (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.

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.
