News For Immediate Release

EAGLE MATERIALS INC. REPORTS CONTINUED

STRONG GROWTH IN SALES VOLUMES AND EARNINGS

IN THE THIRD QUARTER

DALLAS, TX (February 4, 2014)—Eagle Materials Inc. (NYSE: EXP) today reported financial results for the third quarter of fiscal 2014 which ended December 31, 2013. Notable items for the quarter in relation to the prior-year’s third quarter include:

Sales volumes improved across all business lines, with cement volumes setting a third quarter record of over 1.1 million tons sold. Net sales prices also strengthened across all businesses, with wallboard sales prices increasing 19% over the prior year’s third quarter. Quarterly revenue and earnings improvement also reflects the acquisition of assets, primarily two cement plants in Missouri and Oklahoma (the Acquired Assets) on November 30, 2012.

Cement, Concrete and Aggregates

Operating earnings from Cement for the third quarter were $26.0 million, a 57% increase from the same quarter a year ago. The earnings increase resulted from increased sales volumes and average net cement sales prices.

Cement revenues for the quarter, including joint venture and intersegment revenues, totaled $105.6 million, 41% greater than the same quarter last year. The revenue improvement reflects a 36% increase in our third quarter Cement sales volume, including sales volumes attributable to the Acquired Assets. Our average net cement sales price this quarter was $87.01 per ton, 5% higher than the same quarter last year.

Concrete and Aggregates reported a $3.7 million operating loss for the third quarter. The quarterly loss was impacted by start-up costs associated with our new frac sand business of approximately $2.1 million and the settlement of a litigation matter in California for $0.5 million.

Gypsum Wallboard and Paperboard

Gypsum Wallboard and Paperboard’s third quarter operating earnings of $37.4 million were up 51% compared to the same quarter last year. Improved Gypsum Wallboard net sales prices and sales volumes were the primary drivers of the quarterly earnings increase.

Gypsum Wallboard and Paperboard revenues for the third quarter totaled $123.9 million, a 24% increase from the same quarter a year ago. The revenue increase reflects primarily higher wallboard average net sales prices and improved gypsum wallboard and paperboard sales volumes.

The average gypsum wallboard net sales price for the third quarter was $143.40 per MSF, 19% greater than the same quarter a year ago. Gypsum Wallboard sales volume for the quarter of 584 million square feet (MMSF) represents a 13% increase from the same quarter last year. The average Paperboard net sales price for this quarter was $504.08 per ton, 5% greater than the same quarter a year ago. Paperboard sales volumes for the quarter were 66,000 tons, 2% higher than the same quarter a year ago.

Details of Financial Results

For information regarding the results of operations for the 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 Acquired Assets, please see our Form 8-K/A filed on April 26, 2013.

The prior year’s third quarter results include Acquisition and Litigation Expenses related primarily to the acquisition of the Acquired Assets and litigation costs related to our lawsuit against the IRS. The total impact from these non-routine items was $2.8 million (pre-tax), or $0.06 per diluted share (after-tax).

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.
