MANAGEMENT COMMENTARY

Stephen P. Zelnak, Jr., Chairman and CEO of Martin Marietta Materials, stated, "We concluded 2007 with record net sales, operating margin, net earnings and earnings per share in a tough economic environment. We were also on track toward a record fourth quarter until December when significant weather issues in the Mideast, Midwest, and Carolina areas created a 19% drop in volume. Volume in October and November was up nearly 1% over the comparable months of 2006. Pricing in the aggregates product line remained positive for the quarter, but the rate of increase was reduced about 150 basis points based on a heavier-than-usual geographic mix in lower-price areas in the West. The quarter was also negatively affected by the volatility of fuel prices. In the Aggregates business, the rising cost of diesel fuel and liquid asphalt reduced earnings per diluted share by $0.09 for the quarter. Fourth-quarter sales in the Specialty Products business were flat as a result of declining dolomitic lime volumes. Earnings from operations of $8.4 million increased nearly $5 million compared with the prior-year period, which included a $3.8 million charge related to the exit of our composite truck trailer business. On a consolidated basis, earnings per diluted share of $1.33 for the quarter compared with $1.36 in the comparable 2006 period.

"Selling, general and administrative expenses declined 5%, or $2 million, during the quarter and were 7.6% as a percentage of net sales. During the quarter, we further reduced our SG&A headcount by 40 people as we continue to centralize and refine how we operate.

"For the full year 2007, we were able to overcome an 8% volume decline in our heritage aggregates product line with positive pricing of over 10% and good cost management. Our Specialty Products business made a strong contribution with earnings from operations up 46%. Net earnings for the year were $263 million, a 7% increase over 2006, with consolidated operating margin excluding freight and delivery revenues increasing 180 basis points. The 2007 operating margin improvement, when coupled with improvements in 2006, contributed to a 440-basis-point increase in operating margin excluding freight and delivery revenues since 2005. Record net sales of $1.97 billion compared with $1.93 billion in 2006. Earnings per diluted share reached a record $6.06, an increase of 15% over the $5.29 reported in 2006. Return on equity increased 370 basis points to 24%.

"For the year, selling, general and administrative expenses were 7.9% of net sales, compared with 7.6% in 2006. The increase resulted from $6.2 million in increased share-based incentive compensation. Selling, general and administrative expenses for 2007 increased less than 2%, excluding the higher incentive compensation.

"Cash flow (net cash provided by operating activities) increased 17% to $396 million for the year, which supported capital expenditures of $265 million for internal growth projects and acquisition of additional reserve properties, as well as share repurchases. We began work on a major plant project in the Augusta, Georgia, area during the fourth quarter, with completion expected in early 2009. This project, which is the first of a series along the geological fall line in Georgia, will increase capacity at Augusta from 2 million to 6 million tons annually, and is expected to reduce production costs on a per-ton basis. Additional borrowings, coupled with available free cash flow, were used to acquire 4.2 million shares of our common stock. We have repurchased more than 18% of our common shares that were outstanding at the beginning of 2005. We continue to focus on deploying capital and using reasonable, but prudent, leverage in a manner that supports our overriding objective of creating shareholder value. Our priorities remain consistent in that we will continue to invest in internal, organic growth opportunities that improve operational performance or extend our mineral reserve base; opportunistically invest in strategic, value-creating acquisitions; and return available free cash flow to shareholders through sustainable dividends and share repurchase programs while maintaining an investment-grade rating.

2008 Outlook

"We expect 2008 will be a challenging year as we deal with the uncertainty prevalent in the U.S. economy; however, demand for aggregate products in the infrastructure and commercial construction markets appears solid. Many states are exploring new funding alternatives, in addition to federal funding, to meet increasing demand for highways and roads and to mitigate congestion and commute times in urban areas. Commercial demand for industrial-related construction projects is steady and generally low vacancy rates in many of our markets support the fact that office space is not overbuilt. Retail commercial construction is slowing, but demand over the near term should be supported as commercial building catches up with the extended residential buildout. Residential construction is expected to continue to decline, but the recent interest rate cuts by the Federal Reserve Bank should create better conditions in the second half of 2008 and into 2009. However, we do not expect growth in the homebuilding sector to materialize in a significant way until late 2009 or 2010. By contrast, we expect solid growth for chemical-grade aggregates used for flue gas desulfurization and in agriculture lime, as well as ballast used in railroad maintenance. We are also seeing significant demand for new wind farm projects and continuing construction of ethanol plants. In our Specialty Products segment, we expect magnesia-based chemicals products demand to steadily increase as industries focus on clean air, clean water, and other green initiatives. Dolomitic lime demand used in both our chemicals products and as a fluxing agent in steel production should see solid volume growth in 2008.

"The overriding drivers of our performance for 2008 will depend upon a number of macroeconomic factors. Our current view is weighted toward a stabilization of the economy during the second half of 2008, which we believe could provide impetus for increased construction activity to address the underlying demand in the infrastructure and commercial markets and result in an increase in aggregates volumes.

"After careful consideration with respect to the many factors that can affect our performance, especially over the short term, we have decided that we will continue to provide annual earnings guidance, but will eliminate quarterly guidance. We believe that providing annual earnings guidance is more consistent with the approach we take in running our business and provides investors with a view that better aligns them with management's own performance objectives, all of which are based on annual, versus quarterly, targets. If, during the course of the year, events cause us to view the year's performance as being materially different from the guidance we have provided, we will update the guidance as warranted. Also during the course of the year, we will continue to provide quarterly insight into the volume and price drivers that could affect our performance.

"We expect 2008 aggregates volumes will range from up 1% to down 3% and the rate of price increase will be in a range from 5.5% to 7.5%. The relationship between volume and the rate of pricing growth is co-dependent. As volumes increase or decrease, the rate of pricing growth will tend to increase or decrease, but with a lag factor. Our Specialty Products segment, which includes magnesia chemicals, dolomitic lime and targeted activity in structural composites, is expected to contribute $36 million to $38 million in pretax earnings compared with $33 million in 2007.

"In this context, we currently expect record net earnings per diluted share, in a range of $6.25 to $7.00 for 2008," Zelnak concluded.

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, will be, as previously noted, the performance of the United States economy and that performance's effect on construction activity. Management has estimated its earnings range, assuming a stabilization of the United States economy in the second half of 2008. Should the second half 2008 stabilization not occur or if the decline anticipated in the first half 2008 is worse than currently expected, earnings could vary significantly.

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, 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 in 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 affect 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 business is also subject to weather-related risks that can significantly affect production schedules and profitability. 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 on 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 $72,000,000 was outstanding at December 31, 2007.

                     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 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 and year ended December 31, 2007 and 2006 in
 accordance with GAAP and reconciliations of the ratios as percentages
 of total revenues to percentages of net sales:

The increase in operating margin from 2005 to 2007 using the operating
 margin reported in the Corporation's 2005 Annual Report to
 Shareholders is a non-GAAP measure as it excludes the effect of
 divestitures in 2006 and 2007. The Corporation used the 2005
 operating margin as reported in the 2005 Annual Report to
 Shareholders as a baseline for its stated goal of increasing
 operating margin by 1,000 basis points over the five-year period
 ending December 31, 2010. The following reconciles operating margin
 and the increase in operating margin from 2005 to 2007 based on the
