EAGLE MATERIALS INC. REPORTS

FISCAL YEAR AND FOURTH QUARTER RESULTS

DALLAS, TX (May 14, 2013) – Eagle Materials Inc. (NYSE: EXP) today reported financial results for fiscal year 2013 and the fiscal fourth quarter ended March 31, 2013. Notable items for the fiscal year and quarter include:

Fiscal 2013 earnings before interest and income taxes increased 146%, reflecting improved sales volumes across all heritage businesses and higher net sales prices across all businesses, excluding Paperboard, as compared to the prior year. Eagle ended the year with a net debt-to-capitalization ratio of 41%. The results of operations for the recently acquired assets in Oklahoma and Missouri (the “Recently Acquired Assets”) for the period from November 30, 2012 through March 31, 2013, are included in the annual results disclosed in this press release. For information regarding the results of operations for the Recently Acquired Assets for certain periods prior to November 30, 2012, including pro forma financial information that combines the results of operations for Eagle and the Recently Acquired Assets, please see our Form 8-K/A filed on April 26, 2013. The increase in our average shares outstanding at March 31, 2013 is primarily due to the impact of our follow-on equity offering, which was completed on October 3, 2012.

Our fourth quarter results were impacted by non-routine items of approximately $2.4 million, or $0.04 per share, which included the remaining costs associated with finalizing the acquisition of the Recently Acquired Assets and litigation costs related to our lawsuit against the IRS. Additionally, our fourth quarter cement earnings were impacted by approximately $14 million, or $0.21 per share, associated with annual maintenance costs at the Recently Acquired Assets. Start-up costs associated with our recently completed frac sand facility in Corpus Christi were $1 million, or $0.01 per share.

Fourth quarter sales volumes improved across all businesses, reflecting improving construction fundamentals in the US and the addition of the Recently Acquired Assets. In addition, sales prices improved in all businesses other than Paperboard. Gypsum Wallboard experienced the most significant improvement, with an increase in average net sales prices of 23% as compared with the prior year’s fourth quarter.

Cement, Concrete and Aggregates

Fiscal 2013 operating earnings from Cement were $46.2 million, a decline of 1% compared to fiscal 2012. Revenues from Cement, including joint venture and intersegment sales, were $304.1 million for fiscal 2013, 25% higher than last year.

Operating earnings from Cement during the fourth quarter were $2.3 million, a 69% decrease from the same quarter a year ago. Fourth quarter cement earnings were impacted by approximately $14 million associated with maintenance costs at the Recently Acquired Assets, partially offset by improved cement sales volumes and sales prices during the quarter. Cement revenues for the quarter, including joint venture and intersegment revenues, totaled $74.6 million, 50% greater than the same quarter last year. Cement sales volumes for the quarter were 773,000 tons, 45% higher than the same quarter a year ago. The average net sales price for this quarter was $87.81 per ton, 4% higher than the same quarter last year. Like-for-like cement sales volumes and net sales prices increased 10% and 5%, respectively, versus the fourth quarter of fiscal 2012 (comparison relates to sales from heritage cement plants operated by Eagle during both quarterly periods).

Concrete and Aggregates reported a fiscal 2013 operating loss of $5.4 million versus an operating loss of $1.1 million one year earlier reflecting particularly adverse weather during our fourth quarter this year, primarily in the Kansas City area. Revenues from Concrete and Aggregates were $55.5 million for fiscal 2013, 24% higher than last year, reflecting the impact from our recently acquired concrete and aggregates business in Kansas City.

Gypsum Wallboard and Paperboard

Fiscal 2013 operating earnings from Gypsum Wallboard and Paperboard were $94.9 million, an increase of 308% compared to fiscal 2012. Revenues from Gypsum Wallboard and Paperboard were $382.1 million for fiscal 2013, 29% higher than last year’s revenues.

Gypsum Wallboard and Paperboard reported fourth quarter operating earnings of $26.6 million, up 76% from the same quarter last year. The increase in operating earnings was primarily due to higher net wallboard sales prices and sales volumes along with improved paperboard sales volumes offset by lower paperboard sales prices. In addition, our papermill performed its major annual maintenance during the fourth quarter which contributed to the increased operating costs during the fourth quarter.

Gypsum Wallboard and Paperboard revenues for the fourth quarter totaled $95.6 million, a 20% increase from the same quarter a year ago. The average Gypsum Wallboard net sales price for this quarter was $145.72 per MSF, 23% greater than the same quarter a year ago. Gypsum Wallboard sales volumes of 433 million square feet (MMSF) were up approximately 9% from the prior year’s fourth quarter. The average Paperboard net sales price this quarter was $492.54 per ton, 3% less than the same quarter a year ago. Paperboard sales volumes for the quarter were 57,000 tons, 1% greater than the same quarter a year ago.

Details of Financial Results

Current quarter Acquisition and Litigation Expense of $1.8 million consists of costs related to our acquisition of the Recently Acquired Assets and legal fees related to our lawsuit against the IRS.

We conduct one of our cement plant operations through a 50/50 joint venture, Texas Lehigh Cement Company LP (the “Joint Venture”). We utilize the equity method of accounting for our 50% interest in the Joint Venture. For segment reporting purposes only, 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 within Eagle 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 these amounts.
