News For Immediate Release

EAGLE MATERIALS REPORTS FIRST QUARTER EPS UP 22%

ON RECORD REVENUES

DALLAS, TX (July 30, 2018) Eagle Materials Inc. (NYSE: EXP) today reported financial results for the first quarter of fiscal 2019 ended June 30, 2018. Notable items for the quarter are highlighted below. (Unless otherwise noted, all comparisons are with the prior year’s fiscal first quarter):

First Quarter Fiscal 2019 Results

Commenting on the first quarter results, Dave Powers, President and CEO, said, “We are pleased to report another quarter of record revenue and net earnings. We saw strong margin improvement in our Light Materials sector and pricing improved across nearly all businesses during the quarter. We were also pleased to announce the start-up of our new frac sand drying plant in Illinois and we began loading railcars in late June. Tight freight markets continued to limit our ability to move product and led to higher freight costs which impacted net sales prices in both cement and wallboard this quarter.”

Mr. Powers concluded, “Looking ahead, we anticipate another strong year, as the backlog of work in our markets continues to drive demand for our products.”

Segment Results

Heavy Materials: Cement, Concrete and Aggregates

Revenue in the Heavy Materials sector, which includes Cement, Concrete and Aggregates and Joint Venture and intersegment Cement revenue, was $227.3 million, a slight improvement from the first quarter of fiscal 2018. Heavy Materials operating earnings decreased 13% to $42.8 million primarily due to increased maintenance costs resulting from the timing of the annual maintenance outage at our Fairborn Cement plant. Because we had performed an outage at Fairborn after we purchased the plant in March 2017, there was no outage in the quarter ended June 30, 2017.    

Cement revenue for the quarter, including Joint Venture and intersegment revenue, was up 2% to $186.8 million, reflecting higher sales prices. The average net sales price for the quarter improved 2% to $108.69 per ton. Higher freight costs impacted net cement prices by approximately $1.50 per ton during the quarter. Cement sales volume for the quarter was 1.5 million tons, flat with the prior year.

Operating earnings from Cement for the first quarter were $37.3 million, 14% below the same quarter a year ago. The earnings decline was primarily due to the timing of the planned maintenance outage at our Fairborn cement plant partially offset by improved average net cement sales prices.

Concrete and Aggregates revenue for the first quarter of 2019 was $40.5 million, a decrease of 7%. First quarter operating earnings were $5.5 million, a 9% decline, reflecting lower sales volumes partially offset by improved pricing.    

Light Materials: Gypsum Wallboard and Paperboard

Revenue in the Light Materials sector, which includes Gypsum Wallboard and Paperboard, increased 11% to $170.2 million. The improvement reflects higher wallboard sales volume and net sales prices. The average Gypsum Wallboard net sales price for the first quarter of fiscal 2019 was $160.71 per MSF, a 1% improvement. Sequentially, higher freight costs during the quarter impacted the net sales price by approximately $2 per MSF. Gypsum Wallboard sales volume was 710 million square feet (MMSF), up approximately 9%.

The average Paperboard net sales price this quarter was $531.99 per ton, down 3%. Paperboard sales volume for the quarter increased 4% to 82,000 tons.

Operating earnings were $60.5 million in the sector, an increase of 24%, reflecting improved wallboard sales volumes and prices and lower operating costs. The reduced operating costs primarily reflected lower recycled fiber costs during the quarter.

Oil and Gas Proppants

Eagle’s Oil and Gas Proppants segment reported revenue of $21.8 million, an increase of 15%, primarily resulting from a 16% rise in frac sand sales volume. The first quarter’s operating loss of $2.7 million includes $7.1 million of depreciation, depletion and amortization and $1.6 million of start-up costs at our new frac sand facility in Illinois.

Details of Financial Results

The first quarter litigation loss at our Paperboard subsidiary stems from a judgment in a lawsuit filed by some of the plant’s neighbors regarding specific events that occurred in 2010 and 2012. The judgment does not affect ongoing operations.

We conduct one of our cement plant operations through a 50/50 joint venture, Texas Lehigh Cement Company LP (the Joint Venture). We use 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 revenue 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 revenue as a part of a segment’s total revenue. Intersegment sales are eliminated on the income statement. Refer to Attachment 3 for a reconciliation of these amounts.
