EAGLE MATERIALS INC. REPORTS

SECOND QUARTER RESULTS

DALLAS, TX (October 27, 2011)—Eagle Materials Inc. (NYSE: EXP) today reported financial results for the second quarter of fiscal 2012 ended September 30, 2011. Notable items for the quarter include:

Revenues increased 2% from the prior year reflecting improved sales volumes across most of our business lines. Operating earnings were down 6% due primarily to higher raw material costs in our gypsum wallboard segment. Operating cash flow was strong during the quarter, further strengthening our financial position. Prior year’s net earnings include approximately $2.5 million, or $0.06 per diluted share, of tax and interest benefits associated with the final assessment from the IRS related to their audit of the Republic asset acquisition in tax years 2001 through 2006.

Cement, Concrete and Aggregates

Operating earnings from Cement for the second quarter were $15.1 million, a 25% increase from the same quarter a year ago. Cement revenues for the quarter, including joint venture and intersegment revenues, totaled $72.6 million, 7% greater than the same quarter last year. Cement sales volumes for the quarter were 817,000 tons, 5% above the same quarter a year ago. The average net sales price this quarter was $81.23 per ton, 1% higher than the same quarter last year.

Concrete and Aggregates reported a slight operating profit for the second quarter, down from the $0.5 million operating profit for the same quarter a year ago, primarily due to lower aggregates sales volumes and lower concrete average net sales prices.

Revenues from Concrete and Aggregates were $13.7 million for the quarter, 7% greater than the same quarter a year ago. Concrete sales volume increased 17% from the same quarter a

year ago to 144,000 cubic yards. Concrete average net sales price for the quarter of $64.33 per cubic yard was 4% less than the same quarter a year ago. Aggregates sales volume of 0.8 million tons for this quarter was 3% less than the sales volume for the same quarter a year ago. The aggregates average net sales price for the quarter was $5.98 per ton, up 1% compared to last year’s second quarter.

Gypsum Wallboard and Paperboard

Gypsum Wallboard and Paperboard’s second quarter operating earnings of $1.5 million were down 71% compared to the same quarter last year. Lower wallboard average net sales prices and higher raw material costs were the primary driver of the quarterly earnings decline.

Gypsum Wallboard and Paperboard revenues for the second quarter totaled $72.3 million, a 2% increase from the same quarter a year ago. The revenue increase reflects higher wallboard sales volumes and higher paperboard sales prices, offset by lower gypsum wallboard average net sales prices.

The average gypsum wallboard net sales price this quarter was $92.09 per MSF, 4% less than the same quarter a year ago. Gypsum Wallboard sales volume for the quarter of 403 million square feet (MMSF) represents a 2% increase from the same quarter last year. The average Paperboard net sales price this quarter was $524.20 per ton, 11% higher than the same quarter a year ago. Paperboard sales volumes for the quarter were 60,000 tons, 3% lower than the same quarter a year ago.

Details of Financial Results

Texas Lehigh Cement Company LP, one of our cement plant operations, is conducted through a 50/50 joint venture (the “Joint Venture”). We utilize the equity method of accounting for our 50% interest in the Joint Venture. For segment reporting purposes we proportionately consolidate our 50% share of the Joint Venture’s revenues and operating earnings, which is consistent with the way management organizes the segments in the Company for making operating decisions and assessing performance.

In addition, for segment reporting purposes, we report intersegment revenues as a part of a segment’s total revenues. Intersegment sales are eliminated on the income statement. Refer to Attachment 3 for a reconciliation of the amounts referred to above.
