-- Company Reports Fourth Quarter Adjusted EPS of $0.52, Exceeding Market Expectations --

Heritage Aggregates Pricing Growth of 6%

Specialty Products Posts Record Earnings

RALEIGH, N.C.--(BUSINESS WIRE)-- Martin Marietta Materials, Inc. (NYSE:MLM) today announced results for the fourth quarter and year ended December 31, 2011.

Ward Nye, President and CEO of Martin Marietta Materials, stated: "2011 was an exciting year for our company in terms of both strong operational and financial performance and execution against stated strategic objectives. Considering the challenges that confronted the construction materials industry throughout the year, I am pleased that we concluded 2011 with fourth-quarter earnings that exceeded market expectations, before charges related to business development expenses. Underlying these results is a 6% increase in average selling price in our heritage aggregates product line that continued the momentum generated throughout the entire year. Further, our Specialty Products segment established new records for fourth-quarter and annual earnings.

"In addition to delivering strong operating results for the quarter, we completed three aggregates-related acquisitions during 2011, which enhanced our platform for future growth in previously identified target markets. Coupled with tactical execution, our continued disciplined business approach and commitment to fundamentals and strategic vision have once again yielded impressive results, especially in a challenging environment. We are well positioned to continue building long-term shareholder value."

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

Nye continued, "The average selling price in our heritage aggregates product line was, as we expected, a positive trend that started in the first quarter and continued throughout the year. Pricing improved in each of our reporting segments, led by the 7.8% increase in our West Group, which supports our previously stated view that pricing growth is sustainable — despite depression-like shipment declines over the past five years.

"Another key to our strong performance in both the quarter and the full year has been our Specialty Products segment. This business continues to exceed expectations by completing a stellar year and setting new quarterly and annual records for net sales and earnings from operations. Net sales of $51.5 million increased $7.0 million, or 16%, over the prior-year quarter, reflecting growth in both the chemicals and lime product lines. Increased sales and effective cost management resulted in a 600-basis-point improvement in the business' gross margin for the quarter. Earnings from operations were $16.3 million, a 55% increase over the prior-year quarter.

"Cost management is an enduring area of focus throughout our company. In line with that objective, direct production costs for our heritage aggregates product line increased only 1% despite an 11% increase in noncontrollable energy costs (principally diesel fuel), which reduced overall earnings by $0.05 per diluted share and was offset by reductions in personnel and depreciation costs. For the quarter, diesel fuel costs averaged $2.95 per gallon compared with $2.32 per gallon in the prior-year quarter. On a consolidated basis, our cost of sales increased 9.5% over the prior-year quarter, reflecting higher raw materials costs, including liquid asphalt, and the impact from rising energy costs.

"Our SG&A expense continues to differentiate us from others in the industry. On a consolidated basis, SG&A costs for the quarter declined $2.4 million, or 130 basis points as a percentage of net sales, primarily driven by lower pension and incentive compensation expenses. During the quarter, we also completed various restructuring activities. These actions led to $1.6 million of nonrecurring termination costs in the fourth quarter, but should reduce ongoing general and administrative expenses. Interest expense declined $3.6 million due to a higher mix of variable-rate debt, which currently bears a lower interest rate than our fixed-rate debt.

"We incurred $15.1 million of business development expenses during the quarter, including expenses related to completed transactions and expenses related to our exchange offer to effect a business combination with Vulcan Materials Company. For the year, business development expenses were $18.6 million.

"The most significant component of our business development expenses relates to our exchange offer to effect a business combination with Vulcan Materials Company, which would create a United States-based company that is the global leader in construction aggregates with a footprint reaching from coast to coast. Under the terms of the offer, launched on December 12, 2011, each outstanding share of Vulcan would be exchanged for 0.50 of a Martin Marietta share. We believe that a strategic combination of Martin Marietta and Vulcan 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. We are continuing to pursue this combination in 2012.

"During the quarter, we completed a previously announced asset exchange with Lafarge North America Inc., providing our company with a new platform market position in the greater Denver, Colorado, area. In addition to acquiring strategic and attractive aggregates facilities, this swap transaction provides us with complementary downstream asphalt, ready mixed concrete and paving operations. In a subsequent transaction, we acquired a ready mixed concrete business in metropolitan Denver. These cumulative actions are consistent with our view that Denver is an attractive market to expand our geographic footprint based on its strong demographic trends, a per capita income well above the national average and its ability to attract both national and multinational businesses.

"To facilitate the asset exchange, we divested certain operations along the Mississippi River. These assets operated in a fragmented market with a high level of competition, relatively low barriers to entry and did not provide us the best opportunity to achieve our expected long-term return on assets. This swap transaction should not be interpreted as an abandonment of our long-haul distribution strategy, but as the use of our Mississippi River operations as currency for a premier position in a market with attractive growth dynamics to best meet our strategic objectives. We remain fully committed to our leading network of rail and water-served operations and believe this competitive differentiation provides us with the flexibility to effectively serve customers in the high-growth Southeast and Southwest markets.

"As previously noted, heritage aggregates product line shipments declined 1.2% for the quarter; however, volume variances differed significantly by market. Our Mideast Group experienced growth in most of its markets and, for the quarter, reported a 6.6% increase in heritage shipments. This growth stemmed from shipments to the energy sector and the Rebuild Indy program in Indiana. Importantly, the Mideast Group volume increase drove a 60% incremental margin after adjusting for the volatile rise in energy costs. Conversely, our Southeast Group continues to experience weakness in the North Georgia and Alabama markets and reported a heritage volume decline of 6.4% for the quarter.

"Consistent with trends noted throughout the year, the infrastructure market continues to represent more than half of our Aggregates business. Heritage shipments to this end use declined 2% compared with the prior-year quarter. While we are encouraged by the dialogue in Congress regarding the need for a multi-year federal highway bill, infrastructure spending continues to be constrained during short-term extensions of federal highway funding. We continue to anticipate consistent growth in infrastructure spending once long-term federal funding is resolved.

"Heritage aggregates shipments to the residential market increased 2%, reflecting enhanced multi-family construction activity, and heritage shipments to the nonresidential end-use market increased slightly, both compared with the prior-year quarter. Our heritage ChemRock/Rail end-use market decreased 4% from the prior-year quarter, as expected considering the significant volume of agricultural lime shipments in the fourth quarter of 2010.

LIQUIDITY AND CAPITAL RESOURCES

"We concluded 2011 with a characteristically strong cash position, with cash from operating activities for the year ended December 31, 2011, of $259.1 million compared with $269.8 million for 2010. The decrease was primarily due to one-time business development expenses in 2011, offset by an increase in payables, including accruals for certain of those costs. Our days sales outstanding of 47 days was unchanged from 2010 and continues to represent an impressive accomplishment in view of the challenging economic environment.

"For the year, we invested $155.4 million of capital, primarily in maintenance initiatives. We also invested in targeted organic-growth projects, including initiating construction of a $53 million dolomitic lime kiln in Woodville, Ohio, in our Specialty Products business. This project is expected to be substantially completed by late 2012. We also invested $91.6 million for three acquisitions completed during the year.

"At December 31, 2011, our ratio of consolidated debt to consolidated EBITDA, as defined in the accompanying financial statements, for the trailing twelve months was 3.25 times, in compliance with the limit in our debt covenants. Our acquisition-related borrowings increased the limit of the ratio from 3.5 times to 3.75 times for a period of 180 days.

"Our $100 million secured accounts receivable credit facility is scheduled to expire in April 2012. We have initiated communications with our lenders to begin the process of extending the facility for one year.

2012 OUTLOOK

"A variety of factors beyond our direct control continue to make forecasting future performance unclear. Of particular note is the status of long-term federal infrastructure funding and uncertainties surrounding the timing and amount of such funding.

"We continue to be pleased with the positive 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 a key and essential governmental priority. However, the reality of election-year politics in Washington will likely slow progress in passing this needed legislation. Our view is that unless a multi-year surface transportation bill is passed in the early part of the year, its reauthorization will likely fall victim to the partisan political process resulting in the current federal highway program being extended by a ninth continuing resolution through the end of the year. That said, if a bill is passed this year, the impact of its passage will be notable starting in 2013.

"Our expectations for 2012 are generally consistent with the McGraw Hill Construction forecast. Based on the two-fold impact of uncertainty created by the absence of a long-term highway bill, as well as the waning impact of the American Recovery and Reinvestment Act, we expect our heritage infrastructure end-use market volume to be down slightly in 2012. We anticipate double-digit volume growth in our heritage nonresidential end-use market, driven primarily by increased energy shipments, although natural gas prices, the timing of lease commitments for oil and natural gas companies, geographic transitions and weather conditions will continue to affect energy-sector activity. We expect the rate of improvement in our heritage residential end-use market to accelerate in 2012. Finally, our heritage ChemRock/Rail shipments should be relatively flat with 2011. Overall, we expect heritage aggregates product line shipments for full-year 2012 to increase from 3% to 4%.

"We anticipate heritage aggregates pricing increases from 2% to 4%. This overall increase is not expected to be uniform across our company.

"Heritage aggregates product line direct production costs per ton are expected to decline slightly in 2012, as increased production should improve operating efficiency. This forecast assumes energy prices are comparable with 2011.

"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, while Denver has likely weathered the worst of the recession and maintained the features making it a favorite among businesses and new residents, the sheer timing of our early-December asset exchange of more southerly situated River assets for this new Denver business naturally increases our winter weather exposure — and, accordingly, alters our quarterly earnings pattern. Further, our average consolidated aggregate selling price will also change. 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 and absent 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 2012 EBITDA. We expect that this acquisition will be accretive in 2013.

"Earnings for the Specialty Products segment should be approximately $66 million, consistent with 2011. 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 integration of these operations. Interest expense should remain relatively flat with 2011. Our effective tax rate is expected to approximate 26%, excluding discrete events. Capital expenditures are forecast at $155 million for 2012, which includes the remaining $35 million of the $53 million Specialty Products kiln project.

"Our 2012 estimated outlook assumes Martin Marietta on a stand-alone basis and does not give effect to the potential impact of the proposed combination of Martin Marietta and Vulcan Materials Company."

RISKS TO OUTLOOK

The 2012 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 2012 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 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 discontinuance of the federal gasoline tax 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 that disproportionately affect 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 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 2012 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 markup. 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 and year ended December 31, 2011 and 2010, 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)
Adjusted earnings per diluted share ("Adjusted EPS") and the earnings per diluted share impact of business development expenses represent non-GAAP financial measures. Consolidated earnings from operations exclusive of business development expenses also represents a non-GAAP measure. Management presents these measures as it believes Adjusted EPS represents the most comparable operating performance measure to analysts' expectations as they have not factored the impact of business development expenses into their EPS expectations. Further, management believes Adjusted EPS and consolidated earnings from operations exclusive of business development expenses represent more meaningful comparisons of performance considering the significant impact of business development expenses incurred in 2011.
The following shows the calculation of the EPS impact of business development expenses and reconciles earnings per diluted share in accordance with generally accepted accounting principles to Adjusted EPS:
										Three Months Ended						Three Months Ended

Non-GAAP Financial Measures (continued)
(Dollars in millions)
The presentation of incremental operating margin excluding freight and delivery revenues for the Mideast Group, assuming energy costs were equal to the expense in the prior-year quarter, is a non-GAAP financial measure. Management presents this measure, as it believes it helps demonstrate the impact of incremental sales on operating margin due to the significant amount of fixed production costs. The following presents the calculation of the incremental operating margin excluding freight and delivery revenues for the Mideast Group for the quarter ended December 31, 2011, assuming energy costs were equal to the expense for the quarter ended December 31, 2010:
Mideast Group net sales for the quarter ended December 31, 2011																		$	112.7
Mideast Group net sales for the quarter ended December 31, 2010																			101.5
Incremental net sales for the Mideast Group																		$	11.2
Mideast Group earnings from operations for the quarter ended December 31, 2011																		$	18.7
Increase in energy costs for Mideast Group for the quarter ended December 31, 2011																			1.6
Pro forma earnings from operations for Mideast Group for quarter ended December 31, 2011																			20.3
Mideast Group earnings from operations for the quarter ended December 31, 2010																			13.6
Pro forma incremental earnings from operations for the Mideast Group for the quarter ended December 31, 2011, assuming energy costs were equal to the expense in prior-year quarter																		$	6.7
Pro forma incremental operating margin for the Mideast Group for the quarter ended December 31, 2011, assuming energy costs were equal to the expense in prior-year quarter																			60	%
The ratio of Consolidated Debt-to-Consolidated EBITDA, as defined, for the trailing twelve months is a covenant under the Corporation's revolving credit facility, term loan facility and accounts receivable securitization facility. Under the terms of these agreements, the Corporation's ratio of Consolidated Debt-to-Consolidated EBITDA as defined, for the trailing twelve months can not exceed 3.5 times as of the end of any fiscal quarter, with certain exceptions related to qualifying acquisitions, as defined. Acquisition-related borrowings increase the limit of the ratio from 3.5 times to 3.75 times for a period of 180 days, so long as the ratio does not exceed 3.5 times when excluding the acquisition-related borrowings.
