MANAGEMENT COMMENTARY

Stephen P. Zelnak, Jr., Chairman and CEO of Martin Marietta Materials, stated, "We are pleased with our record results for the second quarter, particularly given lower-than-expected demand and severe weather issues in parts of the West. Heritage aggregates pricing increased 13%, offsetting a 9% reduction in volume, which led to a 450-basis-point improvement in aggregates product line gross margin excluding freight and delivery revenues and a 240-basis-point increase in consolidated operating margin excluding freight and delivery revenues. Results include the net benefit of updated inventory standards partially offset by increased management incentive compensation cost. Pricing improvements continue to hold in the Aggregates business in spite of greater-than-expected volume declines. During the quarter, the level of residential construction spending in the United States reached its lowest point since April 2004. Although residential construction contributed only 17% of the Corporation's aggregates product line shipments in 2006, sales to this end-use sector have diminished in virtually every market. In addition, commercial construction activity in the South Central United States, notably, Alabama, Mississippi and Tennessee, is weak.

"Weather also plagued performance during the second quarter. The West Group, particularly Texas, southern Oklahoma and Kansas, experienced near historic levels of rainfall and flooding, which affected both shipments and operations. Volume declines of 9% in these areas had a negative impact on financial performance during the quarter. We do not believe that any significant construction projects have been permanently delayed and we expect the volume for commercial and infrastructure to return to expected levels when the weather conditions normalize.

"During the quarter, we revised our finished goods inventory valuation standards to match finished goods inventory values with the significant escalation in cost, particularly related to the transportation of material to distribution yards. Historically, we have updated inventory standards once a year in the fourth quarter. However, given the magnitude of the cost change and since our inventory turns about once a quarter, this revaluation, which increased inventory values by $9.0 million, more closely approximates our cost of sales. We will continue to review our inventory standards on an ongoing basis.

"Selling, general and administrative expenses for the quarter ended June 30, 2007, was $44.3 million versus $37.1 million in the 2006 period. This increase of $7.2 million was primarily related to a $5.3 million increase in performance-based incentive compensation. SG&A expenses for the six months ended June 30, 2007, increased $9.3 million compared with the 2006 period. After $6.9 million for higher performance-based incentive compensation for the first half of 2007, remaining SG&A expense increased 3% in 2007 over the prior-year period.

"We continue to generate strong cash flow and are well positioned to use excess cash in ways that are beneficial to our shareholders. We repurchased common stock during the quarter, acquiring 1.25 million shares at an aggregate cost of $193 million. Year-to-date, we have repurchased 3.585 million shares of common stock, or 8% of shares outstanding at the beginning of the year, for $495 million. Capital expenditures of $115 million declined $43 million when compared with the prior year due to the completion of several large capital projects in 2006. However, we expect to spend $235 million in capital for 2007 and commence work on major plant projects in the Southeast that will increase capacity and are expected to reduce production costs. Our objective continues to be to increase shareholder returns through the effective utilization of excess cash.

2007 OUTLOOK

"Based upon our strong first-half performance in 2007, we continue to have a positive outlook for the remainder of the year. Aggregates product line pricing is expected to increase 11% to 12% for the year, which is higher than our earlier guidance. However, aggregates shipments are more difficult to estimate for the balance of the year. We currently expect volume to be flat or increase modestly in the second half and to decrease 4% to 6% for the year with the degree of decline predicated on a longer-than-expected correction in the residential construction market, in addition to commercial construction weakness in the Mississippi River markets. We are pleased to see movement in North Carolina toward issuance of $300 million in Grant Anticipation Revenue Vehicles, or GARVEE bonds, as the proceeds from these bonds are earmarked to pay for various federal road projects statewide. We currently expect construction on these projects to begin in 2008. Also, the state recently provided local option taxing authority to counties and municipalities, which should be positive for infrastructure.

"Our Specialty Products segment, which includes magnesia chemicals, dolomitic lime and targeted activity in structural composites, is expected to contribute $33 million to $36 million in pretax earnings in 2007 compared with $22 million in 2006. We expect the magnesia chemicals business to continue to grow and the demand for dolomitic lime from the steel industry to be flat or down slightly.

"Against this backdrop, we currently expect net earnings per diluted share for the third quarter to range from $1.95 to $2.25 and our range for the year is $6.15 to $6.65. In the third quarter, our effective tax rate is expected to be below 30%, which will bring the higher rate of the first two quarters in line with our 32% expectation for the year."

RISKS TO EARNINGS EXPECTATIONS

The 2007 estimated earnings range includes management's assessment of the likelihood of certain risk factors that will affect performance within the range. The level of aggregates demand in the Corporation's end-use markets and the management of production costs will affect profitability in the Aggregates business. Risks to the earnings range are primarily volume-related and include a significant drop in demand as a result of the continued decline in residential construction, a pullback in commercial construction, delays in infrastructure projects, or some combination thereof. Further, increased highway construction funding pressures in North Carolina and South Carolina can affect profitability. Opportunities to reach the upper end of the earnings range depend on the aggregates product line demand exceeding expectations. Production cost in the Aggregates business is sensitive to production levels, energy prices, the costs of repair and supply parts, and the start-up expenses for large-scale plant projects coming on line in 2007. 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 business is also subject to weather-related risks that can significantly affect production schedules and profitability. Current weather predictions are indicating an active 2007 hurricane season in the Atlantic Ocean. In 2006, 74% of net sales for the Aggregates business were generated in the southern tier of the United States, and, accordingly, the Corporation is exposed to significant disruption in profitability from hurricane activity. Risks to earnings outside of the range include a significant increase in volume beyond current expectations and/or a precipitous drop in demand as a result of economic events outside of the Corporation's control.

                     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
 Corporations' 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, 2007 and 2006 in accordance with GAAP and reconciliations of
 the ratios as percentages of total revenues to percentages of net
 sales:
