Martin Marietta Materials, Inc. Announces Record Third-Quarter Results

RALEIGH, N.C., Oct 30, 2007 (BUSINESS WIRE) -- Martin Marietta Materials, Inc. (NYSE:MLM), today announced record net sales, net earnings and earnings per share for the third quarter and nine months ended September 30, 2007. Notable items for the quarter were:

-- Earnings per diluted share of $2.12, up 28% from the prior-year quarter;

-- Net sales of $548.9 million, up 4% compared with the prior-year quarter;

-- Consolidated operating margin excluding freight and delivery revenues of 24.9%, up 290 basis points over the prior-year quarter;

-- Heritage aggregates product line pricing up 8.6%, offsetting a 4% volume decline; and

-- Specialty Products earnings from operations up 76% from the prior-year quarter.

MANAGEMENT COMMENTARY

Stephen P. Zelnak, Jr., Chairman and CEO of Martin Marietta Materials, stated, "We are extremely pleased with our record third quarter results, particularly given the current economic environment. Heritage aggregates pricing increased 8.6%, contributing to a 200-basis-point increase in our heritage aggregates product line gross margin excluding freight and delivery revenues and a 290-basis-point improvement in consolidated operating margin excluding freight and delivery revenues. Our record results were achieved despite a greater than 4% decline in aggregates volume and an increase in production costs resulting from operating leverage and inventory control. Pricing improvements continued to hold in the Aggregates business. As expected, the rate of growth in aggregates pricing slowed during the quarter in response to the effect of more limited 2007 mid-year price increases, which reflects reduced demand over the past six quarters. However, even with weaker demand, the rate of pricing improvement continues to be well above historic norms for the business, which reflects the intrinsic value of well-located, zoned and permitted aggregates reserves.

"While weather continued to affect performance in the West Group during the quarter, the Group finished the quarter with volumes up over 2% and showed significant earnings improvement over the prior-year period. July 2007 was the third wettest July in recorded weather history in Texas and the historic rainfall affected both shipments and operations. However, as dry, hot days began to outnumber wet days in mid-August and September, volume for commercial and infrastructure projects began to return to normal levels. The Raleigh-Durham and Greensboro, North Carolina areas, as well as Virginia, had positive volume growth for the quarter. Volumes declined in most other regions of the country, reflecting the continued diminishment of residential construction coupled with a slowing in the rate of growth of commercial construction, notably office and retail space.

"Our profits also reflected strict adherence to our disciplined control of costs. For the quarter ended September 30, 2007, selling, general and administrative expenses was $36.4 million versus $35.3 million in the 2006 period and, as a percentage of net sales, declined slightly to 6.6%.

"The overall effective tax rate was 25.9% for the quarter compared with 27.6% in the prior year's period. As expected, the effective tax rate was reduced by the impact of discrete tax events during the quarter related to the settlement of certain tax liabilities. These discrete events contributed $0.12 per diluted share to earnings compared with $0.06 per diluted share in the third quarter of 2006. We expect the effective tax rate for the full year to be approximately 30%.

"Cash flow, as measured by net cash provided by operating activities, increased 30% to $273 million for the nine-month period ended September 30, 2007, which supported capital expenditures of $197 million for internal growth projects, acquisition of additional reserve properties, as well as share repurchases. We expect to commence 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. Capital expenditures are expected to be $260 million for the year, up from the previous estimate of $235 million due to the purchase of 50 new barges for $24 million, which originally was expected to be financed through operating leases. Year-to-date, additional borrowings, coupled with available free cash flow, have been used to acquire 3.6 million shares of our common stock. There were no shares repurchased in the third quarter as we were investigating the possibility of some attractive acquisition growth opportunities. 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.

2007 OUTLOOK

"Based upon our strong year-to-date performance, we continue to have a positive outlook for the remainder of the year. Aggregates product line pricing is expected to increase 10% to 11% for the year; however, aggregates shipments are becoming more difficult to estimate. We currently expect aggregates volume to decrease 6% to 8% for the year with the degree of decline predicated on continued correction in the residential construction market, in addition to slower growth in commercial construction. We believe certain commercial construction, notably office and retail space, is exhibiting a cautionary pause in activity in some areas as developers digest the impact of the current credit markets on construction and development plans. Capacity-related, industrial and distribution-related construction remains in a solid growth pattern. Infrastructure spending is expected to remain positive, although rising construction and materials prices have made projects more costly.

"Our Specialty Products segment, which includes magnesia chemicals, dolomitic lime and targeted activity in structural composites, is expected to contribute $31 million to $33 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 down slightly.

"Against this backdrop, we currently expect net earnings per diluted share for the fourth quarter to range from $1.37 to $1.72 and our range for the year is $6.10 to $6.45."

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 greater-than-expected drop in demand during the fourth quarter as a result of the continued decline in residential construction, a pause in commercial construction as developers digest the impact of the current credit markets on construction and development plans, delays in infrastructure projects, or some combination thereof. Further, increased highway construction funding pressures in North Carolina, Texas 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 costs in the Aggregates business is sensitive to production levels, energy prices, the costs of repair and supply parts, and the start-up expenses for the large-scale plant project in Weeping Water, Nebraska, 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. In prior years, fourth quarter results have been adversely affected by hurricane activity and the early onset of winter in the Corporation's northern and midwestern states. 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. In addition to the impact on residential and commercial construction, the Corporation is exposed to risk in its earnings expectations from tightening credit markets, through the interest cost related to its $225,000,000 Floating Rate Senior Notes due in 2010 and the availability 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 $76,000,000 was outstanding at September 30, 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 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 nine months ended
 September 30, 2007 and 2006 in accordance with GAAP and
 reconciliations of the ratios as percentages of total revenues to
 percentages of net sales:
