Heritage Aggregates Shipments Increase 9.6%; Pricing Up 2.8%; Gross Margin Expands

Specialty Products Posts Quarterly Record for Sales and Earnings

Adjusted EPS Improves 23%

Guidance Revised Upward

RALEIGH, N.C.--(BUSINESS WIRE)-- Martin Marietta Materials, Inc. (NYSE:MLM) today announced its results for the first quarter ended March 31, 2012.

Ward Nye, President and CEO of Martin Marietta Materials, stated: "We are pleased with the first-quarter trends in our heritage Aggregates business where we leveraged volume improvement and pricing momentum to achieve a 250-basis-point improvement in gross margin (excluding freight and delivery revenues). Our heritage aggregates product line shipments increased 9.6% and, more significantly, each of our end-use markets experienced volume growth led by the nonresidential and residential markets with increases of 17% and 8%, respectively. Pricing grew 2.8% in our heritage aggregates product line. Our newly acquired platform position in the Denver, Colorado area experienced an expected seasonal loss; however, the magnitude of the seasonal loss was offset somewhat by increased construction activity in the market. We expect these newly acquired assets will continue to benefit from the heightened construction activity in Denver for the rest of the year. We will also focus on bringing this business' cost structure in line with our other operations. Our Specialty Products business continues to perform exceptionally well, establishing a new quarterly record for net sales and a new first-quarter record for earnings from operations. On a consolidated basis, excluding business development expenses and the results from the Denver-based Rocky Mountain Division, our first-quarter operating results were significantly stronger compared with the first quarter of 2011. Based on these business trends, we are increasingly optimistic about our outlook for the remainder of 2012."

MANAGEMENT COMMENTARY (ALL COMPARISONS, UNLESS NOTED, ARE WITH THE PRIOR-YEAR QUARTER)

Nye continued, "We experienced volume growth in each reportable segment, in addition to each end-use market. Moderate winter weather in most of our heritage operating regions was a factor in our increase in heritage aggregates product line shipments. As an example, our Midwest Division, primarily serving Iowa and Nebraska, experienced a 34% increase in heritage aggregates volumes. While a portion of the increase is attributable to strong agricultural lime shipments, this division also benefitted from an improved business environment with growth in its nonresidential market. On a company-wide basis, growth in the nonresidential end-use market was driven by increased shipments for both repair and maintenance projects, as well as energy sector activity. The residential end-use market growth reflects increased single-family housing activity, particularly in the San Antonio, Texas area, which is partly attributable to military base realignment and closure (BRAC) activity. In addition to these previously identified end-use markets, our shipments to the ChemRock/Rail market rose 4%.

"The infrastructure end-use market represented approximately half of our aggregates product line shipments and increased 7% for the quarter. This market continues to be constrained by the uncertainties surrounding a long-term federal highway bill. In March, Congress approved a continuing resolution providing federal highway funding through June 30, 2012, the ninth short-term funding extension since the expiration of the previous multi-year federal highway bill in 2009. During this extended time period of multiple continuing resolutions, states have experienced increased pressure to find means to supplement the financing of infrastructure projects. To that end, we were pleased to see the Texas Department of Transportation announce plans to leverage an additional $2 billion to fund high-priority projects over the next two years. Given our significant presence throughout Texas, this initiative should provide multiple opportunities for our Aggregates business. We also expect to benefit from the planned increase in projects awarded by the North Carolina Department of Transportation in the current fiscal year and beyond. For example, the Garden Parkway toll road is expected to be bid later this year, and we expect to competitively bid on this project. Additionally, in February, the North Carolina Department of Transportation was granted permission from the Federal Highway Administration to collect tolls on Interstate 95 as a mechanism to fund a $4.4 billion plan to overhaul all of the state's 182 miles of I-95, widening the four-lane expressway to six lanes and eight lanes on the busiest 50 miles. Should this I-95 proposal move forward, our company is well-positioned to serve these aggregate-intensive projects.

"Our heritage aggregates product line pricing improvement was led by the 7.7% increase in our West Group, which was partially augmented by pricing increases implemented subsequent to the first quarter of 2011. Aggregates pricing was particularly strong in South Texas where distribution yards, which have a higher average selling price due to an internal freight component, accounted for a higher percentage of shipments. The Southeast Group reported pricing improvement of 2.2% and our Mideast Group reported a 1.8% pricing decline, driven by product mix. As previously indicated during our fourth-quarter and full-year 2011 earnings call, average selling prices at our newly acquired Colorado operations are significantly lower than our heritage aggregates selling price, primarily due to product mix. Sales of base stone, which has a lower average selling price compared with clean stone, comprised a significantly higher percentage of shipments from the newly acquired operations. As a result, overall average selling price for the aggregates product line, inclusive of acquisitions and divestitures, increased 1.1% compared with a 2.8% increase for the heritage business.

"In order to meet higher demand, we increased heritage aggregates product line production by 8.5%. When unplanned production increases occur early in the year, certain direct production costs, such as supplies and repairs, are typically negatively affected. We also continue to absorb the significant financial impact of higher energy expenses, particularly diesel fuel, which represents the single largest component of our energy costs. For the first quarter, we paid an average of $3.24 per gallon compared with $2.81 in the prior-year quarter. Despite these cost pressures, our heritage aggregates product line production cost per ton decreased slightly. On a consolidated basis, cost of sales increased proportionately to the increase in net sales.

"As a reminder, our operating results reflect increased exposure to winter weather resulting from the asset exchange with Lafarge North America Inc. completed in December 2011. In this transaction, we acquired operations in and around the Denver, Colorado area and traded facilities along the Mississippi River. While Denver has likely endured the worst of the recession and maintained its growth and economic features popular among businesses and new residents, the asset exchange of more southerly situated River assets for this Denver business naturally increases our winter weather exposure — and, accordingly, alters our quarterly earnings and cash flow patterns. However, despite Denver's typical winter weather, our first-quarter results from these acquired operations exceeded our expectations due to increased construction activity in the market. Ongoing, we anticipate that these assets will contribute significantly to long-term shareholder value.

"SG&A expenses were 9.4% of net sales, a 50-basis-point reduction compared with the prior-year quarter. On an absolute basis, SG&A expenses increased $4.4 million, as expected, primarily related to the recently acquired operations in the Denver, Colorado market. We continue to focus on SG&A costs and our industry-leading performance in this area. Interest expense declined $4.7 million due to a higher mix of variable-rate debt, which currently bears a lower interest rate than our fixed-rate debt.

"Our Specialty Products business continues to exceed expectations, setting a new quarterly record for net sales as well as a new first-quarter record for earnings from operations. Net sales of $51.7 million increased $2.6 million, or 5%, over the prior-year quarter, reflecting growth in both our chemicals and dolomitic lime product lines. Increased sales, coupled with effective cost control, resulted in earnings from operations of $18.2 million, a 440-basis-point improvement in operating margin excluding freight and delivery revenues. To illustrate the long-term growth in this business, compared with the first quarter of 2009, earnings from operations have nearly tripled and operating margin (excluding freight and delivery revenues) has expanded 1,610 basis points.

"Any report on our business would not be complete without an update on our continuing efforts to effect a business combination with Vulcan Materials Company ("Vulcan"). As you know, our proposed business combination with Vulcan would, if successful, create a United States-based company that is a global leader in construction aggregates with a footprint reaching from coast to coast. We believe that this strategic combination of our two companies is compelling financially and operationally, and that such a combination provides significant benefits for shareholders of both companies, as well as employees, customers and communities. During the first four months of this year, we have worked with the Department of Justice on its regulatory review of the proposed transaction and are pleased with the progress in this important area. Additionally, while awaiting the Chancellor's ruling following a bench trial in the Delaware Chancery Court related to certain aspects of the exchange offer, we are proceeding with our effort to elect four directors to the Vulcan Board at its Annual Meeting scheduled for June 1, 2012. Given the classified nature of Vulcan's Board of Directors, the slate we are proposing, if elected, would not constitute a majority of Vulcan's directors. However, we expect that these nominees, if elected, would bring a fresh, independent perspective to the Vulcan Boardroom as to whether Vulcan should engage with Martin Marietta on its business combination proposal. Of course, our efforts in pursuing this business combination have financial ramifications and for the quarter, we incurred $25.9 million of business development expenses.

LIQUIDITY AND CAPITAL RESOURCES

"Our balance sheet continues to be one of the strongest in the industry. Cash used for operating activities for the quarter ended March 31 was $4.3 million in 2012 compared with cash provided by operating activities of $21.3 million for 2011. The decrease was primarily due to lower consolidated net earnings in 2012, which were negatively affected by increased business development expenses. Additionally, the previously mentioned asset exchange with Lafarge North America changed the timing of cash flows throughout the year, with increased cash flows generated by the Denver operations expected to be realized later in the year. Our days sales outstanding was 45 days, unchanged from 2011.

"During the quarter ended March 31, 2012, we invested $37.5 million of capital into our business. This amount reflects the continued construction of a $53 million dolomitic lime kiln in Woodville, Ohio, in our Specialty Products business. Once completed, the new kiln is expected to generate annual net sales ranging from $22 million to $25 million. This project is expected to be substantially completed by the end of the year.

"At March 31, 2012, our ratio of consolidated debt to consolidated EBITDA, as defined, for the trailing twelve months was 3.53 times. During the quarter, we amended the covenant to ensure our available liquidity is not negatively affected by the impact of business development expenses and the seasonality of our working capital for the newly acquired Colorado operations. As amended, the maximum ratio is 3.95 times at March 31, 2012 and June 30, 2012, stepping down to 3.75 times at September 30, 2012, before returning to the pre-amendment maximum of 3.50 times at December 31, 2012.

2012 OUTLOOK

"As previously noted, we are increasingly optimistic for the remainder of the year. We are encouraged by our first-quarter aggregates product line shipment trends, and as a result, have revised our heritage volume guidance accordingly. We expect our infrastructure end-use market volume to range from flat to down slightly. We anticipate double-digit volume growth in our nonresidential end-use market, driven primarily by increased energy shipments, although some energy-sector activity will continue to be affected by natural gas prices, the timing of lease commitments for oil and natural gas companies, geographic transitions and weather conditions. We expect the rate of improvement in our residential end-use market to accelerate over the rate of improvement in 2011. Finally, our ChemRock/Rail shipments should be relatively flat.

"On another positive note, we are gratified by the sentiments and dialogue in Washington, D.C. regarding the need for a multi-year surface transportation bill and its role in jobs creation. In his State of the Union address on January 25th, the President called for money that was previously being spent for wars in Iraq and Afghanistan to be used to rebuild America's infrastructure. Further, there is seeming bipartisan Congressional agreement that infrastructure is an essential governmental priority. However, the reality of election-year politics will likely slow progress in passing this needed legislation. As we have previously stated, we believe it is likely that transportation reauthorization will likely be stymied by the political process resulting in the current federal highway program being extended by continuing resolutions through the end of the year. Should a bill be passed this year, its impact will not be notable before 2013.

"Based on these factors, we anticipate heritage aggregates product line shipments for the full year to increase from 4% to 5% and heritage aggregates pricing to increase from 2% to 4%. A variety of factors beyond our direct control may exert pressure on our volumes, and our pricing increase is not expected to be uniform across our company.

"Heritage aggregates product line direct production costs per ton are expected to decline slightly, as increased production should improve operating efficiency. This forecast assumes efficiencies created by higher production volumes are able to offset increases in energy prices.

"As previously indicated, the platform acquisition of our new Denver, Colorado-based business is consistent with one of our clearly articulated long-term strategies: to be in attractive growth areas with a leading market position — thereby permitting greater operational efficiencies, customer service and growth opportunities. Economic forecasts consistently show Denver's population growing at a faster-than-average pace, with commensurate jobs growth. Still, as evident in our first-quarter results, our consolidated aggregates average selling price is changing. Our former Mississippi River-based business was largely a long-haul enterprise with selling prices inclusive of the embedded costs in transporting aggregates from a producing location to a distant sales yard from which a customer made its purchase. By contrast, Denver is a truck-served market with the typical sales transaction completed at the producing location without transportation costs. Overall, as we integrate these operations into our disciplined cost structure, we estimate that the exchange of the River assets for the Denver assets is neutral to our full-year EBITDA. We expect that this acquisition will be accretive in 2013.

"Earnings for the Specialty Products segment should be approximately $68 million to $70 million. Steel utilization and natural gas prices are two key drivers for this segment.

"SG&A expenses, excluding the incremental expense related to the newly acquired operations in Denver, are expected to decline slightly. We expect favorable improvement in SG&A expenses related to our Denver-based acquisitions as we complete the integration of these operations. Interest expense should remain relatively flat compared with 2011. Our effective tax rate is expected to approximate 22%, excluding discrete events. Capital expenditures are forecast at $155 million, which includes the remainder of the $53 million Specialty Products kiln project.

"Our 2012 estimated outlook assumes Martin Marietta on a stand-alone basis and does not consider any effects that would flow from the proposed combination of Martin Marietta and Vulcan."

RISKS TO OUTLOOK

The full-year estimated outlook includes management's assessment of the likelihood of certain risk factors that will affect performance. The most significant risk to 2012 performance will be the United States economy and its impact on construction activity. In addition, our future performance, including the full-year estimated outlook, could be affected by our proposal to combine Martin Marietta with Vulcan Materials Company as announced on December 12, 2011. For a discussion of the potential risks and other implications of the proposed transaction, please see the prospectus/offer to exchange included in Martin Marietta's Registration Statement on Form S-4 filed on December 12, 2011 (as may be amended from time to time), as well as the Risk Factors section of the Corporation's current annual report on Form 10-K and Martin Marietta's other disclosures relating to the combination proposal.

Other risks related to the Corporation's future performance include, but are not limited to: both price and volume and include a recurrence of widespread decline in aggregates volume negatively affecting aggregates price; the termination, capping and/or reduction of the federal and/or state gasoline tax(es) or other revenue related to infrastructure construction; a greater-than-expected decline in infrastructure construction as a result of continued delays in traditional federal, state and/or local infrastructure projects and continued uncertainty regarding the timing and amount of a successor federal highway bill; a decline in nonresidential construction, a slowdown in the residential construction recovery, or some combination thereof. Further, increased highway construction funding pressures resulting from either federal or state issues can affect profitability. Currently, nearly all states have general fund budget pressures driven by lower tax revenues. If these pressures negatively affect transportation budgets more than in the past, construction spending could be reduced. North Carolina and Texas, states disproportionately affecting our revenue and profitability, are among the states experiencing these fiscal pressures, although recent statistics indicate that transportation budgets and tax revenues are increasing.

The Corporation's principal business serves customers in construction aggregates-related markets. This concentration could increase the risk of potential losses on customer receivables; however, payment bonds normally posted on public projects, together with lien rights on private projects, help to mitigate the risk of uncollectible receivables. The level of aggregates demand in the Corporation's end-use markets, production levels and the management of production costs will affect the operating leverage of the Aggregates business and, therefore, profitability. Production costs in the Aggregates business are also sensitive to energy prices, both directly and indirectly. Diesel fuel and other consumables change production costs directly through consumption or indirectly by increased energy-related input costs, such as, steel, explosives, tires and conveyor belts. Fluctuating diesel fuel pricing also affects transportation costs, primarily through fuel surcharges in the Corporation's long-haul distribution network. The Specialty Products business is sensitive to the absolute price and fluctuations in the cost of natural gas. However, due to recent technology developments allowing the harvesting of abundant natural gas supplies in the U.S., natural gas prices have stabilized.

Transportation in the Corporation's long-haul network, particularly rail cars and locomotive power to move trains, affects our ability to efficiently transport material into certain markets, most notably Texas, Florida and the Gulf Coast. The availability of trucks to transport our product, particularly in markets experiencing increased demand due to energy sector activity, is also a risk. The Aggregates business is also subject to weather-related risks that can significantly affect production schedules and profitability. The first and fourth quarters are most adversely affected by winter weather, and the recent acquisitions of operations in the Denver, Colorado, market increased the Corporation's exposure to winter weather. Hurricane activity in the Atlantic Ocean and Gulf Coast generally is most active during the third and fourth quarters.

Risks to the full-year outlook include shipment declines as a result of economic events beyond the Corporation's control. In addition to the impact on nonresidential and residential construction, the Corporation is exposed to risk in its estimated outlook from credit markets and the availability of and interest cost related to its debt.

Non-GAAP Financial Measures
(Dollars in millions)
Gross margin as a percentage of net sales and operating margin as a percentage of net sales represent non-GAAP measures. The Corporation presents these ratios calculated based on net sales as it is consistent with the basis by which management reviews the Corporation's operating results. Further, management believes it is consistent with the basis by which investors analyze the Corporation's operating results given that freight and delivery revenues and costs represent pass-throughs and have no profit mark-up. Gross margin and operating margin calculated as percentages of total revenues represent the most directly comparable financial measures calculated in accordance with generally accepted accounting principles ("GAAP"). The following tables present the calculations of gross margin and operating margin for the three months ended March 31, 2012 and 2011 in accordance with GAAP and reconciliations of the ratios as percentages of total revenues to percentages of net sales:

Non-GAAP Financial Measures (continued)
(Dollars, other than earnings per share amounts, and number of shares in millions)
The impact of business development expenses and the impact from newly acquired operations on the loss per diluted share represent non-GAAP financial measures. Consolidated loss from operations excluding business development expenses and adjusted loss per diluted share, which excludes the impact of business development expenses and the impact of newly acquired operations, also represent non-GAAP measures. Management presents these measures to provide more consistent information for investors and analysts to use when comparing operating results for the quarter ended March 31, 2012 with the prior-year quarter.
The following shows the calculation of the impact of business development expenses and the newly acquired operations on the loss per diluted share:
