EAGLE MATERIALS INC. REPORTS CONTINUED

GROWTH IN SALES VOLUMES AND EARNINGS

IN THE SECOND QUARTER

DALLAS, TX (October 29, 2012)—Eagle Materials Inc. (NYSE: EXP) today reported financial results for the second quarter of fiscal 2013 which ended September 30, 2012. Notable items for the quarter include (all comparisons, unless noted, are with the prior-year’s second quarter):

Second quarter sales volumes improved across all major business lines and wallboard net sales prices increased 30% as compared to the prior year’s second quarter. Improved second quarter operating cash flow was used to fund capital expenditures, pay dividends and reduce debt which further strengthened our financial position. Eagle ended the quarter with a net debt-to-capitalization ratio of 29%.

As previously announced on September 26, 2012, Eagle entered into a definitive agreement with Lafarge North America to purchase Lafarge’s Sugar Creek, Missouri and Tulsa, Oklahoma cement plants, as well as related assets, which include six distribution terminals, two aggregates quarries, eight ready-mix concrete plants and a fly ash business (the “Lafarge Target Business”).

The purchase price is $446 million, subject to customary post-closing adjustments. Eagle expects that the acquisition will increase its U.S. annual cement capacity by approximately 60% to nearly 5 million tons. The acquisition is expected to close in November or December 2012, and is subject to receipt of required regulatory approvals, certain third-party consents and other customary conditions.

On October 3, 2012, Eagle also completed the public offering of 3.45 million shares of its common stock, which includes 450,000 shares issued pursuant to the underwriters’ exercise in full of their overallotment option, at a price to the public of $46.50 per share. Total gross proceeds from the equity offering were $160.4 million. Net proceeds from the offering were approximately $154.4 million, after deducting underwriting discounts, commissions and expenses related to the offering. The Company intends to use the net proceeds, together with borrowings under its bank credit facility, to fund the pending acquisition of the Lafarge Target Business.

Cement, Concrete and Aggregates

Operating earnings from Cement for the second quarter were $17.4 million, a 15% increase from the same quarter a year ago. Cement revenues for the quarter, including joint venture and intersegment revenues, totaled $78.5 million, 8% greater than the same quarter last year. Cement sales volumes for the quarter were 864,000 tons, 6% above the same quarter a year ago. The average net sales price this quarter was $82.77 per ton, 2% higher than the same quarter last year.

Concrete and Aggregates reported a $0.4 million operating loss for the second quarter, down from a slight operating profit for the same quarter a year ago, primarily due to lower concrete sales volumes and lower aggregates sales volumes in Northern California.

Gypsum Wallboard and Paperboard

Gypsum Wallboard and Paperboard’s second quarter operating earnings of $24.2 million were up 1,513% compared to the same quarter last year. Higher wallboard average net sales prices, higher gypsum wallboard and gypsum paperboard sales volumes and lower recycled paper input costs were the primary driver of the quarterly earnings increase.

Gypsum Wallboard and Paperboard revenues for the second quarter totaled $96.5 million, a 33% increase from the same quarter a year ago. The revenue increase reflects primarily higher wallboard average net sales prices and sales volumes.

The average gypsum wallboard net sales price for the second quarter was $119.44 per MSF, 30% greater than the same quarter a year ago. Gypsum Wallboard sales volume for the quarter of 500 million square feet (MMSF) represents a 24% increase from the same quarter last year. The average Paperboard net sales price for this quarter was $512.12 per ton, 2% lower than the same quarter a year ago. Paperboard sales volumes for the quarter were 62,000 tons, 3% higher than the same quarter a year ago.

Details of Financial Results

Acquisition and Litigation Expense consists of direct costs related to our pending acquisition of the Lafarge Target Business and the write-off of deferred project costs associated with a greenfield cement project that will no longer be pursued due to the pending acquisition and

legal fees related to our lawsuit against the IRS. Direct acquisition costs were approximately $3.5 million (pre-tax), greenfield write-off costs were approximately $1.0 million (pre-tax) and legal fees were approximately $1.2 million (pre-tax) during the quarter ended September 30, 2012.

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.

Non-GAAP Financial Measures

(unaudited)

(Dollars, other than earnings per share amounts, and number of shares in millions)

Adjusted earnings per diluted share (Adjusted EPS) is a non-GAAP financial measure and represents earnings per diluted share excluding the impacts from non-routine items, including costs related to our pending acquisition of the Lafarge Target Business and litigation costs related to our lawsuit against the IRS (Non-routine Items). Management uses measures of earnings excluding the impact of Non-routine Items as a basis for comparing operating results of the Company from period to period and for purposes of its budgeting and planning processes. Management believes Adjusted EPS represents the most comparable operating performance measure to compare the three months ended September 30, 2012 to the same period during the prior year. Although management believes that Adjusted EPS is useful in evaluating the Company’s business, this information should be considered as supplemental in nature and is not meant to be considered in isolation, or as a substitute for earnings per diluted share and the related financial information prepared in accordance with GAAP. In addition, our presentation of Adjusted EPS may not be the same as similarly titled measures reported by other companies, limiting its usefulness as a comparative measure.

The following shows the calculation of Adjusted EPS and reconciles Adjusted EPS to earnings per diluted share in accordance with GAAP for the three months ended September 30, 2012:
