See appendix to this earnings release for a reconciliation to reported earnings per diluted share under GAAP.
2020 earnings from operations, net earnings attributable to Martin Marietta, Adjusted EBITDA and earnings per diluted share included $69.9 million, $54.1 million, $69.9 million and $0.87 per diluted share, respectively, of gains on surplus land sales and divested assets. These gains were nonrecurring in nature.

Ward Nye, Chairman and CEO of Martin Marietta, stated, "Our third-quarter results demonstrate Martin Marietta's industry-leading performance and disciplined execution of our proven Strategic Operating Analysis and Review (SOAR) plan. We established new quarterly records for revenues, gross profit, Adjusted EBITDA (excluding the $69.9 million of nonrecurring gains in third-quarter 2020) and earnings per diluted share (excluding the $0.87 per share of nonrecurring gains in third-quarter 2020). These strong quarterly results were primarily driven by organic shipment growth, pricing gains and value-enhancing acquisitions, which more than offset higher energy-related costs. Importantly, the year's first nine months concluded with the best safety performance in our history.

"Martin Marietta is well positioned to capitalize on the secular demand trends across our geographic footprint, including single-family housing strength, expanded federal- and state-level infrastructure investment and light nonresidential recovery. These trends should support growing construction activity and contribute to attractive pricing acceleration for heavy-side building materials. Our overall confidence is augmented by our newly completed acquisition of Lehigh Hanson, Inc.'s West Region business ("Lehigh West Region"), which further enhanced our pipeline of growth opportunities and deep bench of talent at Martin Marietta. This SOAR-aligned, strategic transaction provides attractive new growth platforms for Martin Marietta's continued geographic expansion, especially in key California and Arizona regions, where we are poised to benefit from favorable market dynamics and accelerating public and private construction activity."

Mr. Nye concluded, "Underpinned by our record-setting safety, operational and financial performance, we are highly confident about Martin Marietta's future. Our focus remains on building the safest, best performing and most durable aggregates-led public company. With our steadfast commitment to employee health and safety, disciplined pricing, operational excellence, sustainable business practices and strategy execution, we are confident Martin Marietta will continue delivering attractive growth and superior value for all of our stakeholders as we SOAR to a Sustainable Future."

Third-Quarter Operating and Financial Results

(All comparisons are versus the prior-year third quarter unless noted otherwise)

Building Materials Business

The Building Materials business achieved record products and services revenues of $1,390.8 million, a 17.3 percent increase, and record product gross profit of $413.1 million, a 7.9 percent increase.

The Building Materials business experienced growing product demand across its three primary end-use markets. However, contractor capacity constraints, including transportation availability and labor shortages, combined with wet weather in several markets, muted third-quarter shipment growth.

Aggregates

Third-quarter aggregates shipments, including shipments from acquired operations, grew 10.2 percent. Acquired operations have selling prices below the Company's average, which limited pricing growth to 1.2 percent.

On an organic basis, aggregates shipments increased 6.0 percent while pricing increased 2.2 percent, reflecting a higher percentage of lower-priced base stone shipments and opportunistic sales of low-priced excess fill material.

By segment:

East Group total shipments increased 10.1 percent and benefitted from robust construction activity across all three primary end-use markets and shipments from the recently acquired Minnesota-based operations. Pricing increased 0.4 percent, inclusive of acquisitions. On a mix-adjusted basis, East Group pricing grew 2.5 percent.
West Group shipments increased 10.4 percent from strong underlying demand in both Texas and Colorado, improving energy-sector activity and shipments from a recent bolt-on acquisition in Texas. Pricing increased 2.8 percent.

Third-quarter aggregates product gross margin decreased 220 basis points to 34.2 percent, driven primarily by $11.7 million in higher diesel costs and a $5.9 million increase in cost of revenues from the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting. Excluding the impact of acquisition accounting, adjusted aggregates product gross margin was 34.9 percent.

Cement

Cement shipments increased 4.1 percent, benefitting from robust construction activity throughout the Texas Triangle and improving demand for specialty oil-well cement products. Pricing grew 8.4 percent, or 6.6 percent on a mix-adjusted basis, reflecting periodic price increases.

Cement product gross margin declined 250 basis points to 37.7 percent as higher energy and raw materials costs outpaced shipment and pricing gains.

Downstream businesses

Ready mixed concrete shipments increased 23.2 percent, or 20.5 percent organically, reflecting the healthy Texas and Colorado demand environment. Pricing increased 2.3 percent following the implementation of mid-year price increases in Texas. Product gross margin expanded modestly to 9.8 percent, as volume and pricing growth overcame higher raw material and diesel costs.

Total asphalt shipments increased 115.9 percent as incremental volume from the acquired Minnesota operations more than offset Colorado shipment declines resulting from late-summer liquid asphalt shortages that have since been resolved. Asphalt pricing decreased 1.7 percent, reflecting a higher percentage of lower-priced shipments from the Company's newly-acquired Minnesota business. Organic pricing increased 1.2 percent. Asphalt and paving products and services gross margin decreased 530 basis points, driven by higher raw material costs and operational disruptions from the Colorado liquid asphalt shortage.

Magnesia Specialties Business

Magnesia Specialties product revenues increased 30.3 percent to a record $71.9 million, driven by improving domestic steel production and global demand for magnesia chemicals products. Product gross margin improved 100 basis points to 39.0 percent as revenue growth more than offset higher costs for energy and contract services.

Consolidated

For comparative purposes, third-quarter 2020 other operating income, net, included $69.9 million of gains on surplus land sales and divested assets. These gains, which were nonrecurring in nature, contributed $0.87 per share to third-quarter 2020 earnings per diluted share.

Cash Generation, Capital Allocation and Liquidity

Cash provided by operating activities for the nine months ended September 30, 2021 was $780.3 million compared with $684.0 million for the prior-year period.

Cash paid for property, plant and equipment additions for the nine months ended September 30, 2021 was $321.3 million. For the full-year, capital expenditures are expected to range from $475 million to $525 million.

In July 2021, the Company issued $2.5 billion of debt to fund the Lehigh West Region acquisition, which closed on October 1, 2021, and other general corporate purposes. The newly-issued debt reflects a weighted-average interest rate of 2.2 percent.

The Company extended the maturity of its $400 million trade receivable securitization facility by one year to September 21, 2022.

Through dividend payments and share repurchases, the Company returned $109.7 million to shareholders in the first nine months of 2021 and over $1.9 billion since announcing a 20 million share repurchase authorization in February 2015.

As of September 30, 2021, the Company had $2.4 billion of cash, cash equivalents and restricted cash on hand and nearly $1.1 billion of unused borrowing capacity on its existing credit facilities. On October 1, 2021, the Company completed its acquisition of Lehigh West Region for $2.3 billion in cash.

Full-Year 2021 Guidance

Full-year 2021 guidance has been updated to reflect the Company's year-to-date performance, continuing energy-related cost headwinds, and expected contributions from acquisitions closed in the fourth quarter.

* Guidance range represents the low end and high end of the respective line items provided above.

Consolidated products and services revenues exclude $395 million to $405 million related to estimated interproduct sales and exclude freight revenues.
Ranges do not include estimates for the increase in cost of revenues from the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting for the Lehigh West Region transaction.
Adjusted gross profit is a non-GAAP financial measure and, in each case, excludes an increase in cost of revenues from the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting.
Adjusted EBITDA is a non-GAAP financial measure. See Appendix to this earnings release for a reconciliation to net earnings attributable to Martin Marietta.
Organic volume % growth range is for organic aggregates shipments, inclusive of internal tons, and is in comparison with organic 2020 shipments of 185.7 million tons.
Total volume % growth range is for total aggregates shipments, inclusive of internal tons, and is in comparison with total 2020 shipments of 186.5 million tons.
ASP % growth range is in comparison with 2020 ASP of $14.77 per ton.

Preliminary View of 2022

The Company's preliminary view of 2022 anticipates organic aggregates shipments to increase in the low-to-mid-single-digits as third-party labor and logistics challenges continue to impact an otherwise robust product demand environment. Martin Marietta remains confident that favorable pricing dynamics will continue, supported by the Company's locally-driven pricing strategy, and anticipates mid-to-high-single-digit growth in organic aggregates pricing in 2022.

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 accompanying 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.

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, give the investor 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", "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.

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 those posed by the COVID-19 pandemic and implementation of any such related response plans; the fluctuations in COVID-19 cases in the United States and the extent that geography of outbreak primarily matches the regions in which the Company's Building Materials business principally operates; the resiliency and potential declines of the Company's various construction end-use markets; the potential negative impact of the COVID-19 pandemic on the Company's ability to continue supplying heavy-side building materials and related services at normal levels or at all in the Company's key regions; the duration, impact and severity of the impacts of the COVID-19 pandemic on the Company, including the markets in which it does business, its suppliers, customers or other business partners as well as on its employees; the economic impact of government responses to the pandemic; the performance of the United States economy, including the impact on the economy of the COVID-19 pandemic and governmental orders restricting activities imposed to prevent further outbreak of COVID-19; 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, most particularly in Texas, Colorado, North Carolina, Georgia, Florida, Iowa, Minnesota and Maryland; the impact of governmental orders restricting activities imposed to prevent further outbreak of COVID-19 on travel, potentially reducing state fuel tax revenues used to fund highway projects; 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 the commercial component of the nonresidential construction market, notably office and retail space, including a decline resulting from economic distress related to the COVID-19 pandemic; 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, 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 and Gulf of Mexico hurricane activity, 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; whether the Company's operations will continue to be treated as "essential" operations under applicable government orders restricting business activities imposed to prevent further outbreak of COVID-19 or, even if so treated, whether site-specific health and safety concerns might otherwise require certain of the Company's operations to be halted for some period of time; 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; increasing governmental regulation, including environmental laws; 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 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, 2020, Martin Marietta's Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021 and June 30, 2021, and other periodic filings made with the SEC.

Non-GAAP Financial Measures

Earnings before interest; income taxes; depreciation, depletion and amortization expense; the earnings/loss from nonconsolidated equity affiliates; acquisition-related expenses; and the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting (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. 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.
