EAGLE MATERIALS INC. REPORTS

RECORD FISCAL YEAR

DALLAS, TX (May 18, 2016) – Eagle Materials Inc. (NYSE: EXP) today reported financial results for fiscal year 2016 and the fiscal fourth quarter ended March 31, 2016. Notable items for the fiscal year and quarter include (all comparisons, unless otherwise noted, are with the prior fiscal year or prior year’s fiscal fourth quarter):

Company Annual Results

Company Fourth Quarter Results

Note: The prior year included a net benefit of $0.33 per diluted share related to the settlement of our lawsuit against the IRS and acquisition and litigation costs

Other Highlights

Eagle’s construction products and building materials businesses performed well during the quarter, with the Cement business reporting record fourth quarter operating earnings of $21.8 million. Additionally, in Texas, increased demand for construction grade cement continues to offset much of the impact from lower oil well cement demand.

Our fourth quarter Gypsum wallboard sales volumes benefited from pre-buying activity in advance of a March 31 price increase, which was not the case in the prior year’s fourth quarter.

Fiscal 2016 cash flow from operations improved 14% and was used to fund capital improvements, pay dividends, reduce debt and repurchase shares. Eagle ended the quarter with a net debt-to-capitalization ratio of 33%.

Cement, Concrete and Aggregates

Fiscal 2016 operating earnings from Cement were a record $137.9 million, an increase of 17% compared to fiscal 2015. Revenues from Cement, including joint venture and intersegment sales, were $528.5 million for fiscal 2016, 8% higher than last year.

Fourth quarter operating earnings from Cement were a record $21.8 million, a 4% increase from the same quarter a year ago. Cement revenues for the quarter, including joint venture and intersegment revenues, totaled $100.1 million, 10% greater than the same quarter last year. Cement sales volumes for the quarter were 879,000 tons, 6% higher than the same quarter a year ago. The average net sales price for this quarter was $100.41 per ton, a slight improvement from the same quarter last year.

Concrete and Aggregates reported fiscal 2016 operating earnings of $9.8 million, up 46% compared to the prior year. Revenues from Concrete and Aggregates were $127.2 million for fiscal 2016, 19% higher than last year.

Gypsum Wallboard and Paperboard

Fiscal 2016 operating earnings from Gypsum Wallboard and Paperboard were $191.5 million, an increase of 8% compared to fiscal 2015. Revenues from Gypsum Wallboard and Paperboard were $551.6 million for fiscal 2016, 5% higher than last year’s revenues.

Gypsum Wallboard and Paperboard reported fourth quarter operating earnings of $51.2 million, up 34% from the same quarter last year. The increase in operating earnings was primarily due to higher wallboard and paperboard sales volumes.

Gypsum Wallboard and Paperboard revenues for the fourth quarter totaled $140.9 million, a 26% increase from the same quarter a year ago. The average Gypsum Wallboard net sales price for this quarter was $152.80 per MSF, 10% less than the same quarter a year ago. Gypsum Wallboard sales volumes of 630 million square feet (MMSF) were up approximately 36% from the prior year’s fourth quarter. The average Paperboard net sales price this quarter was $502.21 per ton, 3% less than the same quarter a year ago. Paperboard sales volumes for the quarter were 73,000 tons, 28% greater than the same quarter a year ago.

Oil and Gas Proppants

Eagle’s Oil and Gas Proppants business reported fiscal 2016 revenues of $57.6 million, a decline of 29% from the prior year, which reflects the significant slowdown in oil and gas drilling activity during our fiscal year. The fiscal 2016 operating loss was $68.5 million, which includes $37.8 million of Non-Routine Items recorded in the second quarter of fiscal 2016 and depreciation, depletion and amortization expense of $27.2 million. Sequentially, the fourth quarter’s operating loss of $9.1 million compares to an operating loss of $9.2 million in the third quarter. Our frac sand sales volume declined 4% sequentially.

Details of Financial Results

During the prior year’s fourth quarter, Eagle’s settlement with the IRS regarding the Republic acquisition was finalized. Under the terms of the settlement agreement, we dismissed our lawsuit seeking to recover taxes, penalties and interest paid, in exchange for the IRS conceding 40% of the penalties, plus related interest, to date. The tax impact from the settlement with the IRS, including state benefits, was approximately $16.6 million, or $0.33 per diluted share, and was recorded as a reduction of income tax expense during the fourth quarter. The related interest award of approximately $4.4 million (pre-tax), or $0.06 per diluted share (after-tax), was recorded as a reduction of interest expense.

The prior year’s fourth quarter financial results were also negatively impacted by business development expenses aimed at growing Eagle’s construction products business and administrative costs related to our settlement of our lawsuit against the IRS. The total impact from these non-routine items was $4.1 million (pre-tax), or $0.06 per diluted share (after-tax).

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.

The principal risks and uncertainties that may affect the Company’s actual performance include the following: the cyclical and seasonal nature of the Company’s business; public infrastructure expenditures; adverse weather conditions; the fact that our products are commodities and that prices for our products are subject to material fluctuation due to market conditions and other factors beyond our control; availability of raw materials; changes in energy costs including, without limitation, natural gas, coal and oil; changes in the cost and availability of transportation; unexpected operational difficulties, including unexpected maintenance costs, equipment downtime and interruption of production; fluctuations in activity in the oil and gas industry, including the level of drilling and fracturing activity and demand for frac sand; inability to timely execute announced capacity expansions; difficulties and delays in the development of new business lines; governmental regulation and changes in governmental and public policy (including, without limitation, climate change regulation); possible outcomes of pending or future litigation or arbitration proceedings or governmental audits, inquiries or investigations; changes in economic conditions specific to any one or more of the Company’s markets; competition; announced increases in capacity in the gypsum wallboard and cement industries; changes in the demand for residential housing construction or commercial construction; general economic conditions; and interest rates.
