EAGLE MATERIALS REPORTS

RECORD THIRD QUARTER EPS UP 27% ON RECORD REVENUES

DALLAS, TX (January 24, 2017) – Eagle Materials Inc. (NYSE: EXP) today reported financial results for the third quarter of fiscal 2017 ended December 31, 2016. Notable items for the quarter include (all comparisons, unless otherwise noted, are with the prior year’s third quarter):

Company Third Quarter Results

Eagle’s construction products and building materials businesses performed exceptionally well during the quarter, with Eagle’s Cement, Paper and Concrete and Aggregates businesses all reporting record third quarter operating earnings. Third quarter cash flow from operations improved 18% and was used to fund capital improvements, pay dividends and reduce debt.

As previously announced, on September 11, 2016, Eagle entered into a definitive agreement with a subsidiary of CEMEX S.A.B. de C.V. (“Cemex”) to purchase Cemex’s Fairborn, Ohio cement plant and related assets. The purchase price is $400 million, subject to customary post-closing adjustments. Eagle expects that the acquisition will increase its U.S. annual cement capacity by approximately 20% to nearly 6 million tons. The transaction is expected to close in Eagle’s fiscal fourth quarter. During the third quarter, Eagle incurred nearly $1 million of integration and related costs associated with the transaction. Eagle intends to finance the acquisition through a combination of cash on hand and borrowings under its existing bank credit facility.

Cement, Concrete and Aggregates

Cement revenues for the third quarter, including joint venture and intersegment revenues, totaled $138.0 million, which was 2% higher than the same quarter last year. The average net sales price for this quarter was $100.88 per ton, 4% higher than the same quarter last year. Wholly-owned average net sales prices improved 6% from the third quarter last year. The average net cement sales price at our Joint Venture declined year-over-year reflecting the shift from oil well cement to construction-grade cement over the past year; however, operating earnings improved 7% at the Joint Venture. Total Cement sales volumes for the quarter were 1.2 million tons, 1% lower than the same quarter a year ago, reflecting early winter conditions in our northern markets.

Operating earnings from Cement for the third quarter were a record $45.3 million and 8% greater than the same quarter a year ago. The earnings improvement was driven primarily by improved average net cement sales prices and lower raw material and energy costs.

Concrete and Aggregates reported revenues for the third quarter of $40.6 million, an increase of 29%. Third quarter operating earnings were $4.6 million, a 202% improvement from the same quarter a year ago, reflecting record quarterly concrete sales volumes and record third quarter concrete and aggregates sales prices.

Gypsum Wallboard and Paperboard

Gypsum Wallboard and Paperboard revenues for the third quarter totaled $146.9 million, which were 12% greater than the same quarter a year ago. The average Gypsum Wallboard net sales price this quarter was $153.34 per MSF, 3% less than the same quarter a year ago. Gypsum Wallboard sales volume for the quarter of 646 million square feet (MMSF) represents a 14% increase from the same quarter last year. Paperboard sales volumes for the quarter were 76,000 tons, 7% greater than the same quarter a year ago. The average Paperboard net sales price this quarter was $524.75 per ton, 3% greater than the same quarter a year ago.

Gypsum Wallboard and Paperboard reported third quarter operating earnings of $50.5 million, up 12% from the same quarter last year. The earnings improvement primarily reflects improved Gypsum Wallboard and Paperboard sales volumes.

Oil and Gas Proppants

Oil and Gas Proppants reported third quarter revenues of $7.1 million, a 16% decrease from the prior year’s third quarter primarily reflecting lower average net sales prices partially offset by a 7% increase in frac sand sales volumes from the prior year. The third quarter’s operating loss of $1.7 million includes depreciation, depletion and amortization of $5.0 million. During the third quarter, we also recognized a $4.1 million pre-tax gain on settlement associated with the termination of one of our long-term frac sand customer contracts.

Details of Financial Results

We conduct one of our cement plant operations, Texas Lehigh Cement Company LP, 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 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 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.
