The Corporation’s sales and earnings are predominately derived from its aggregates segment, which processes and sells granite, sandstone, limestone, and other aggregates products from a network of approximately 300 quarries and distribution facilities in more than 20 states in the southeastern, southwestern, midwestern and central regions of the United States and in the Bahama Islands and Canada. The division’s products are used primarily by commercial customers principally in domestic construction of highways and other infrastructure projects and for commercial and residential buildings. As a result of 1998 and 1999 acquisitions of asphalt production, ready mixed concrete operations and road construction companies, the Corporation vertically integrated in other construction materials businesses in Louisiana, Arkansas and Texas. The magnesia-based products segment produces refractory materials and dolomitic lime used in domestic and foreign basic steel production and produces chemicals products used in industrial, agricultural and environmental applications. The magnesia-based products segment derives a major portion of its sales and earnings from the products used in the steel industry. <P align="left"> RESULTS OF OPERATIONS Consolidated net sales for the quarter were $276.1 million, a 14% increase over 1999 first quarter sales of $241.0 million. Consolidated earnings from operations were $20.1 million in the first three months of 2000 compared with $16.1 million in the first three months of 1999. Consolidated net earnings for the quarter were $7.3 million, or $0.16 per diluted share, a decrease of $0.6 million from 1999 first quarter net earnings of $7.9 million, or $0.17 per diluted share. <P align="left"> Sales for the Aggregates division increased 17% to $243.7 million for the first quarter of 2000, compared with the year-earlier period. The division’s operating profits were $17.7 million for the period compared to the prior year’s first quarter earnings from operations of $15.6 million. The increase in sales resulted primarily from strong performance in both volume and pricing in the Corporation’s heritage aggregates operations. Operating margin from heritage operations increased almost 100 basis points during the quarter when compared to the prior year’s comparable quarter. During the quarter, the division was able to overcome the negative impact of record snowfall in North Carolina, as well as a significant increase in diesel fuel costs in excess of the comparable prior-year period. <P align="left"> The Aggregates division’s business is significantly impacted by seasonal changes and other weather-related conditions. Consequently, the Aggregates division’s production and shipment levels coincide with general construction activity levels, most of which occur in the division’s markets typically during the spring, summer, and fall seasons. Management continues to believe the construction industry’s overall aggregates annual consumption level and the Corporation’s annual production and shipments, excluding acquisitions, will experience moderate overall growth for the full year 2000, compared with the prior year. Further, management continues to believe that average selling prices for heritage aggregates operations are expected to increase 3% to 4%, outpacing potential increases in production costs in 2000 for comparable heritage aggregates operations. During the quarter ended March 31, 2000, heritage aggregates shipments volume increased almost 2% and average selling prices increased 4.6%. However, because of the potentially significant impact of weather on the Corporation’s operations, first quarter results are not necessarily indicative of expected performance for the year. Yet, for 2000, management currently believes that strong first-quarter performance will be followed by strong performance for the year; although there are no guarantees of such performance. <P align="left"> The Magnesia Specialties division had first quarter 2000 sales of $32.4 million, a slight increase of approximately 1% compared with the first three months of 1999. The division’s first quarter earnings from operations increased to $2.4 million from $0.5 million in the first quarter of 1999, as business experienced a stronger operating environment as compared to the prior year. Magnesia Specialties division’s increased sales and earnings in the first quarter resulted from improving steel industry performance, continued strong chemicals sales and a better balance between production and sales. <P align="center"> (Continued) <DIV align="center"> Page 9 of 18 </DIV> <!-- PAGEBREAK --> <P><HR noshade><P> <P align="center">MARTIN MARIETTA MATERIALS, INC.

In addition to several offsetting amounts, other income and expenses, net, are comprised generally of interest income, gains and losses associated with the disposition of certain assets, gains and losses related to certain amounts receivable, income from non-operating services, costs associated with the commercialization of certain new technologies, and net equity earnings from non-consolidated investments. Further, in 1999, other income and expenses, net, included a non-recurring settlement from an antitrust claim. <P align="left"> Interest expense was $10.2 million in the first quarter, compared to $9.2 million in the first quarter of 1999. <P align="left"> The Corporation’s estimated effective income tax rate for the first three months was 35.3% in 2000 and 34.9% in 1999. See Note 4 of the Notes to Condensed Consolidated Financial Statements. <P align="left"> LIQUIDITY AND CAPITAL RESOURCES Net cash flow provided by operating activities during the first quarter of 2000 was $26.7 million compared with $29.2 million in the comparable period of 1999. The cash flow for both 2000 and 1999 was principally from earnings, before deducting depreciation, depletion and amortization, offset by working capital requirements. Depreciation, depletion and amortization was $33.1 million and $29.4 million for the three months ended March 31, 2000 and 1999, respectively. The seasonal nature of the construction aggregates business impacts quarterly net cash provided by operating activities when compared with the year. Full year 1999 net cash provided by operating activities was $223.7 million, compared with $29.2 million provided by operations in the first quarter of 1999. <P align="left"> First quarter capital expenditures, exclusive of acquisitions, were $34.0 million in 2000 and $29.0 million in 1999. Capital expenditures are expected to be approximately $220 million for 2000, exclusive of acquisitions. Comparable full year capital expenditures were $137.8 million in 1999. During the first quarter 2000, the Corporation spent $14.2 million in continuation of its expansion strategy. <P align="left"> The Corporation continues to rely upon internally generated funds and access to capital markets, including its two revolving credit agreements and a cash management facility, to meet its liquidity requirements, finance its operations, and fund its capital requirements. With respect to the Corporation’s ability to access the public market, currently, management has the authority to file a universal shelf registration statement with the Commission for up to $500 million in issuance of either debt or equity securities. It should be noted, however, that the Corporation has not determined the timing when, or the amount for which, it may file such shelf registration. <P align="center">(Continued) <DIV align="center"> Page 11 of 18 </DIV> <!-- PAGEBREAK --> <P><HR noshade><P> <P align="center">MARTIN MARIETTA MATERIALS, INC.

The Corporation may be required to obtain additional levels of financing in order to fund certain strategic acquisitions if any such opportunities arise. Currently, the Corporation’s senior unsecured debt is rated “A” by Standard & Poor’s and “A3” by Moody’s. The Corporation’s commercial paper obligations are rated “A-1” by Standard & Poor’s, “P-2” by Moody’s and “F-1” by Fitch IBCA, Inc. While management believes its credit ratings will remain at an investment-grade level, no assurance can be given that these ratings will remain at the above-mentioned levels. <P align="center">Page 12 of 18 <!-- PAGEBREAK --> <P><HR noshade><P> <P align="center">MARTIN MARIETTA MATERIALS, INC.
