Martin Marietta Materials, Inc. Increases Third-Quarter and Annual Earnings Range - To Broadcast Third-Quarter Conference Call Live on the Internet

RALEIGH, North Carolina (October 4, 2005) - Martin Marietta Materials, Inc. (NYSE:MLM), today announced that it expects third quarter earnings to be in a range from $1.61 to $1.66 per diluted share, including a one-time benefit of an estimated $0.17 per share from a decrease in estimated tax liabilities. Earnings in the prior-year period were $1.11 per share. The expected results are higher than the previously announced third quarter earnings per share range. The earnings increase is primarily attributable to continued strong aggregates pricing, solid volume and good cost management, in spite of an environment of escalating fuel-related costs and the negative impact of Hurricanes Katrina and Rita on the Corporation's operations. A nonrecurring write down of $1.5 million of composites-related inventory is also included in the earnings range.

We expect net earnings per share for 2005 to range from $3.80 to $3.95 per share inclusive of the aforementioned one-time tax benefit. As is customary with the seasonality of the Corporation's business, the fourth quarter is subject to weather-related risk from both the continuation of record 2005 hurricane activity and the affects of winter on the Corporation's operations. Other factors that will affect fourth quarter performance include the volatility of energy prices, control of the rising costs of supply parts and wages and benefits and residential construction strength.

The Corporation will provide an online Web simulcast of its third-quarter 2005 earnings conference call on Tuesday, November 1, 2005. The Company will release results for the quarter and nine-months ended September 30, 2005, that morning before the market opens.

The live broadcast of Martin Marietta Materials' conference call will begin at 2 p.m. Eastern Time on November 1, 2005. An online replay will be available approximately two hours following the conclusion of the live broadcast and will continue for one year.
