EAGLE MATERIALS REPORTS FIRST QUARTER RESULTS

DALLAS, TX (July 28, 2021) Eagle Materials Inc. (NYSE: EXP) today reported financial results for the first quarter of fiscal 2022 ended June 30, 2021. 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 2022 Highlights

Commenting on the first quarter results, Michael Haack, President and CEO, said, “Fiscal 2022 is off to a good start for Eagle. In the first quarter we achieved record revenue of $476 million and net earnings per diluted share of $2.25. These results reflect strong market demand in both of our major business lines and exceptional operational execution by our team. Our Wallboard business continues to benefit from robust residential construction activity across our markets, and our Cement business benefited from sustained high levels of infrastructure spending. Gross margin increased to 26.6%, an improvement of 260 basis points over the prior year, in spite of heavy rainfall in our Texas markets, which resulted in lower Cement sales volume, and additional Cement maintenance costs this quarter compared with a year ago.”

Mr. Haack continued, “We expect underlying market conditions to remain strong as the US economy recovers, and we are well-positioned to continue to benefit from this growth. On July 1, 2021, we completed the issuance of $750 million of 10-year senior notes with an interest rate of 2.50%, which further strengthened our capital structure. We also restarted our share repurchase program and repurchased approximately 426,000 shares of our common stock during the quarter. With Eagle’s excellent balance sheet and steadfast execution of our operating strategies, we are extremely well-positioned for a strong fiscal 2022.”

Segment Financial Results

Heavy Materials: Cement, Concrete and Aggregates

Revenue in the Heavy Materials sector, which includes Cement, Concrete and Aggregates, Joint Venture and intersegment Cement revenue, was $315.0 million, a 3% improvement. Heavy Materials operating earnings also increased 3% to $67.9 million primarily because of improved Cement sales prices.

Cement revenue, including Joint Venture and intersegment revenue, was up 3% to $270.3 million. Operating earnings were also up 3% to a record $62.5 million. These increases reflect improved Cement quarterly sales prices, partially offset by lower Cement sales volume. The average net Cement sales price for the quarter was up 7% to $116.34 per ton. Cement sales volume for the quarter was down 2% to 2.0 million tons, mainly because of heavy rainfall in Texas during the quarter.

Concrete and Aggregates revenue increased 2% to $44.8 million, reflecting improved Concrete and Aggregates prices, partially offset by lower Aggregates sales volume. First quarter operating earnings decreased 1% to $5.3 million, reflecting lower Aggregates sales volume partially offset by improved Concrete and Aggregates net sales prices.

Light Materials: Gypsum Wallboard and Paperboard

Revenue in the Light Materials sector, which includes Gypsum Wallboard and Paperboard, increased 25% to $191.3 million, reflecting higher Wallboard sales volume and prices. Gypsum Wallboard sales volume increased 8% to 763 million square feet (MMSF), while the average Gypsum Wallboard net sales price increased 21% to $176.79 per MSF.

Paperboard sales volume increased 9% to a record 84,000 tons. The average Paperboard net sales price in the quarter was $498.49 per ton, up 8%, consistent with the pricing provisions in our long-term sales agreements.

Operating earnings were $66.6 million in the sector, an increase of 51%, reflecting increased Wallboard sales volume and pricing.

Details of Financial Results

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 the Company 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.

On September 18, 2020, the Company sold its Oil and Gas Proppants business to Smart Sand, Inc. The prior-year financial results of the Oil and Gas Proppants segment have been classified as Discontinued Operations on the Consolidated Statement of Earnings. The assets and liabilities of the Oil and Gas Proppants segment have been reflected on separate lines for Discontinued Operations on the Consolidated Balance Sheet.

This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, Section 21E of the Securities Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the context of the statement and generally arise when the Company is discussing its beliefs, estimates or expectations. These statements are not historical facts or guarantees of future performance but instead represent only the Company’s belief at the time the statements were made regarding future events which are subject to certain risks, uncertainties and other factors, many of which are outside the Company’s control. Actual results and outcomes may differ materially from what is expressed or forecast in such forward-looking statements. 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 businesses; 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 the costs of energy, including, without limitation, natural gas, coal and oil, and the nature of our obligations to counterparties under energy supply contracts, such as those related to market conditions (such as fluctuations in spot market prices), governmental orders and other matters; changes in the cost and availability of transportation; unexpected operational difficulties, including unexpected maintenance costs, equipment downtime and interruption of production; material nonpayment or non-performance by any of our key customers; fluctuations in or changes in the nature of activity in the oil and gas industry; 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 and other environmental regulation); possible outcomes of pending or future litigation or arbitration proceedings; changes in economic conditions specific to any one or more of the Company’s markets; severe weather conditions (such as winter storms, tornados and hurricanes) on our facilities, operations and contractual arrangements with third parties; competition; cyber-attacks or data security breaches; announced increases in capacity in the gypsum wallboard and cement industries; changes in the demand for residential housing construction or commercial construction or construction projects undertaken by state or local governments; risks related to pursuit of acquisitions, joint ventures and other transactions or the execution or implementation of such transactions, including the integration of operations acquired by the Company; general economic conditions; and interest rates. For example, increases in interest rates, decreases in demand for construction materials or increases in the cost of energy (including, without limitation, natural gas, coal and oil) could affect the revenue and operating earnings of our operations.
