MANAGEMENT COMMENTARY

Stephen P. Zelnak, Jr., Chairman and CEO of Martin Marietta Materials, stated, "Second-quarter results highlighted our ability to successfully operate in one of the most challenging economic environments in our industry's history. We faced diesel fuel and natural gas costs that escalated nearly 60%, a ninth consecutive quarter of declining aggregates volume and its resulting impact on our operating leverage as production volumes were aligned with sales expectations. Nonetheless, our management team and employees did an excellent job of matching operating levels with demand and aggressively addressed controllable costs.

"Despite the reduced demand, we continued to achieve sustainable pricing growth within all groups of the aggregates business as overall pricing for aggregates was up over 6% for the quarter. The West Group again reported positive volume levels for its aggregates product line, resulting from the comparative strength of the infrastructure and commercial construction markets in Texas, Oklahoma, and Iowa. Shipments in Iowa increased over 9% during the quarter despite severe flooding in much of the state; however, lower production levels and higher operating costs as a result of the flooding had a negative impact on profitability compared with expectations and the prior-year period. Infrastructure demand in other key states, including North Carolina and Georgia, remains challenging to forecast as rising costs for construction materials have constrained state highway budgets, as well as municipal spending. Demand dropped significantly in the Mideast Group, as the usually resilient North Carolina and South Carolina markets experience the effects of residential construction declines in addition to weakening infrastructure expenditures. Several states are taking active measures to address their infrastructure funding needs; however, it is difficult to predict the impact of these measures on volume levels for the remainder of 2008.

"The rapid and extreme increases in the cost of petroleum-based products affected both our costs and sales. Liquid asphalt, used in the production of asphalt paving products, increased approximately 135% over the prior year with average prices approaching $700 per ton. Our customers cannot react quickly enough to these escalating costs and, when possible, have made the choice to defer work in anticipation of future potential cost reductions. Cost control initiatives in place throughout the Corporation served to limit the increase in consolidated cost of sales despite the nearly 60% increase in diesel fuel and natural gas costs compared with the prior-year quarter. The rise in the cost of petroleum-based products alone resulted in additional production costs of $18 million, or $0.26 per diluted share, for the quarter. Compounding the sharply-escalating energy costs, the Corporation incurred expenses of $24 million, or $0.35 per diluted share, to control aggregates production and reduce inventory levels.

"The focus and execution on cost control also extended to our overhead costs. Selling, general and administrative expenses decreased by $2.3 million in terms of absolute dollars and as a percentage of net sales to 8.0% from 8.4% for the prior-year quarter.

"We completed the acquisition and highly-successful integration of the operations acquired from Vulcan Materials Company in the previously announced asset exchange transaction during the quarter. The Corporation recorded a total gain on the exchange transaction of $16.4 million. Of this total gain, $7.2 million has been reported in other operating income of both the West and Mideast Groups. The remainder of the gain has been reported as part of discontinued operations.

"During the quarter, we received some very positive news in North Carolina. The legislature passed a budget that provided funding for the construction of four toll road projects for a total of $3.2 billion. The first of these projects is scheduled for letting in the third quarter of this year with completion in 2011. It is valued at approximately $1 billion and will consume about 2 million tons of aggregates. Two additional projects will begin in 2009 and the remaining one is scheduled for 2010. These three projects are estimated to consume 4.5 million tons of aggregates. Of the total 6.5 million tons for the four projects, we should be fully competitive on about 85%.

"Finally, in another positive development, we now expect that our new plant in Augusta, Georgia, will begin operations in the fourth quarter of 2008 versus the prior forecast of second quarter 2009. The earlier completion of this project, which increases capacity from 2 million tons to 6 million tons annually, is enabling us to engage in marketing discussions with major customers. We expect that this will increase our market share in high-growth markets in Georgia and Florida.

"Our Specialty Products business continues to perform exceptionally well. The United States' steel market has remained strong, leading to increased demand for dolomitic lime. We've experienced increased demand for magnesia-based chemicals products used in a number of environmental applications as well as for our flame retardant products. The business delivered record second-quarter net sales of $45.2 million, an increase of 14% compared with the prior-year quarter, and record earnings from operations of $9.7 million, an increase of 20% compared with the prior-year quarter. The business' operating margin excluding freight and delivery revenues increased 120 basis points to 21.6% for the quarter.

2008 OUTLOOK

"Our 2008 outlook has turned decidedly more cautious in the past few months as the shock of high oil prices has affected both demand for our products and our costs. A challenging economic environment, energy inflation, credit market uncertainty and lagging infrastructure demand make forecasting increasingly difficult. Accordingly, we are adjusting downward our range for 2008 net earnings per diluted share to $5.00 to $5.65 from $6.25 to $7.00. Even in this difficult environment, however, our outlook for 2008 pricing in our Aggregates business remains positive. Accordingly, we reaffirm our 6.0% to 8.0% range for the rate of heritage aggregates price increases in 2008.

"Over the balance of the year, we expect infrastructure volumes in certain of our key states to be affected more by funding limitations than underlying demand. In addition, the sharp increase in diesel fuel prices may continue to affect infrastructure volume as customers do not have funding mechanisms to react quickly to the increases currently being experienced in liquid asphalt and other petroleum-based raw materials. However, assuming that recent downward trends in oil and commodity pricing continue, this could be a catalyst in turning demand in a positive direction. Residential construction continues to be dismal, but we still expect that large industrial commercial projects will be a plus for second-half 2008 results.

"As a result, we are lowering our range for 2008 heritage aggregates volumes to be down 3% to down 6%, both exclusive of acquisitions. We also expect to deliver record levels of net sales and earnings from both our lime and magnesia chemicals businesses and reaffirm our guidance of $36 million to $38 million in pretax earnings from Specialty Products."

RISKS TO EARNINGS EXPECTATIONS

The 2008 estimated earnings range includes management's assessment of the likelihood of certain risk factors that will affect performance within the range. The most significant risk to 2008 earnings, whether within or outside current earnings expectations, continues to be the performance of the United States economy and its effect on construction activity.

Risks to the earnings range are primarily volume-related and include a greater-than-expected drop in demand as a result of the continued decline in residential construction, a decline in commercial construction, delays in infrastructure projects, or some combination thereof. Further, increased highway construction funding pressures as a result of either federal or state issues can affect profitability. Currently, North Carolina, Georgia, Texas, and South Carolina are experiencing state-level funding pressures, and these states may disproportionately affect profitability. 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, the costs of repair and supply parts, and the start-up expenses for large-scale plant projects. The continued rising cost of diesel and other fuels increases production costs either directly through consumption or indirectly through the increased cost of energy-related consumables, namely steel, explosives, tires and conveyor belts. Sustained periods of diesel fuel cost at the current level will continue to have a negative impact on profitability. The availability of transportation in the Corporation's long-haul network, particularly the availability of barges on the Mississippi River system and the availability of rail cars and locomotive power to move trains, affects the Corporation's ability to efficiently transport material into certain markets, most notably Texas and the Gulf Coast region. The Aggregates business is also subject to weather-related risks that can significantly affect production schedules and profitability. Hurricane activity in the Atlantic Ocean and Gulf Coast generally is most active during the third and fourth quarters. Opportunities to reach the upper end of the earnings range depend on the aggregates product line demand exceeding expectations.

Risks to earnings outside of the range include a change in volume beyond current expectations as a result of economic events outside of the Corporation's control. In addition to the impact of residential and commercial construction, the Corporation is exposed to risk in its earnings expectations from tightening credit markets and the availability of and interest cost related to its commercial paper program, which is rated A-2 by Standards & Poor's and P-2 by Moody's. Commercial paper of $75 million was outstanding at June 30, 2008.

                     Non-GAAP Financial Measures
                            (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 and six months ended
 June 30, 2008 and 2007, in accordance with GAAP and reconciliations
 of the ratios as percentages of total revenues to percentages of net
 sales:
