News For Immediate Release

EAGLE MATERIALS REPORTS RECORD FIRST QUARTER RESULTS WITH 24% EPS GROWTH

DALLAS, TX (July 27, 2023) Eagle Materials Inc. (NYSE: EXP) today reported financial results for the first quarter of fiscal 2024 ended June 30, 2023. 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 2024 Highlights

Commenting on the first quarter results, Michael Haack, President and CEO, said, “Fiscal 2024 is off to a solid start for Eagle, with record revenue of $602 million, adjusted EPS of $3.55, and gross margins of 29.3%, an increase of 240 bps. Our portfolio of businesses continued to perform well, and we made progress on our strategic priorities. During the quarter, we reached an important milestone in the production of Portland Limestone Cement, surpassing 50% across our system. We completed the acquisition of a cement import terminal in northern California that further strengthens our competitive position in that market. And we returned $83 million of cash to shareholders through share repurchases and dividends, all while maintaining our balance sheet strength: at June 30, 2023, Eagle’s net debt was $1.1 billion, and our net adjusted leverage ratio (net debt to Adjusted EBITDA) remained at 1.4x, giving us substantial financial flexibility for continued disciplined capital allocation.”

Mr. Haack continued, “Looking ahead to the balance of the year, we expect demand for cement to remain steady driven by infrastructure and heavy industrial projects. Residential construction activity remains resilient as the market balances interest rate-related affordability challenges with chronic supply shortages and strong demand. Given Eagle’s balance sheet strength, the favorable geographic positioning of our operations, and our consistent operational and strategic execution, we are poised for a strong fiscal 2024.”

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 $396 million, a 15% improvement. Heavy Materials operating earnings increased 19% to $81 million primarily because of higher Cement sales prices and sales volume partially offset by increased maintenance costs and the effects of an extended maintenance outage at our Joint Venture.

Cement revenue, including Joint Venture and intersegment revenue, was up 16% to $329 million. Operating earnings increased 19% to $74 million reflecting higher Cement sales prices and sales volume partially offset by increased maintenance costs and the impact from the step-up in inventory values related to the Stockton Terminal Acquisition. Profitability at our Joint Venture was negatively affected by an extended outage during the quarter to address ongoing equipment issues at this facility over the past year. The extended outage resulted in increased maintenance costs and reduced production. Equipment reliability has improved in July, but additional work will need to be completed during our planned maintenance outage in fiscal 2025, which will again increase the outage timeline at the joint venture facility.

The average net Cement sales price for the quarter increased 15% to $147.27 per ton. Cement sales volume for the quarter increased 1% to 2.0 million tons. Sales volume in the quarter was affected by wet weather in the western part of the US.

Concrete and Aggregates revenue was up 9% to $67 million, reflecting increased Concrete and Aggregates prices and higher aggregates sales volume. First quarter operating earnings increased 23% to $7 million. The increase reflects higher Concrete and Aggregates net sales prices and approximately $1.2 million of additional costs incurred in the first quarter of fiscal 2023 from the step-up in inventory values related to the acquisition of an aggregates business in northern Colorado.

Light Materials: Gypsum Wallboard and Paperboard

Revenue in the Light Materials sector, which includes Gypsum Wallboard and Paperboard, decreased 2% to $242 million, primarily because of lower Gypsum Wallboard sales volume, partially offset by improved Gypsum Wallboard sales prices. Gypsum Wallboard sales volume declined 4% to 763 million square feet (MMSF), while the average Gypsum Wallboard net sales price increased 8% to $236.66 per MSF.

Paperboard sales volume was down 1% to 83,000 tons. The average Paperboard net sales price in the quarter was $536.56 per ton, down 12%, consistent with the pricing provisions in our long-term sales agreements that factor in lower input costs.

Operating earnings were $98 million in the Light Materials sector, an increase of 12%, reflecting higher Gypsum Wallboard sales prices and lower operating costs, most notably energy and recycled fiber.

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.

Reconciliation of Non-GAAP Financial Measures

(unaudited)

(dollars in thousands, other than earnings per share amounts, and number of shares in thousands)

Adjusted Earnings per Diluted Share (Adjusted EPS)

Adjusted EPS is a non-GAAP financial measure and represents net earnings per diluted share excluding the impacts from non-routine items, such as purchase accounting and accelerated equity compensation (Non-routine Items). Management uses measures of earnings excluding the impact of Non-routine Items as a performance measure in order to compare operating results of the Company from period to period and for purposes of its budgeting and planning processes. Although management believes that Adjusted EPS is useful in evaluating the Company’s business, this information should be considered as supplemental in nature and is not meant to be considered in isolation, or as a substitute for, earnings per diluted share and the related financial information prepared in accordance with GAAP. In addition, our presentation of Adjusted EPS may not be the same as similarly titled measures reported by other companies, limiting its usefulness as a comparative measure. The following shows the calculation of Adjusted EPS and reconciles Adjusted EPS to net earnings per diluted share in accordance with GAAP for the quarters ended June 30, 2023 and 2022:

¹ Represents the impact of purchase accounting on inventory costs and related business development costs

² Represents additional equity compensation costs associated with the retirement of two senior executives during the respective quarters

Attachment 6, continued

EBITDA and Adjusted EBITDA

We present Earnings before Interest, Taxes, Depreciation and Amortization (EBITDA) and Adjusted EBITDA to provide more consistent comparison of operating performance from period to period. EBITDA is a non-GAAP financial measure that provides supplemental information regarding the operating performance of our business without regard to financing methods, capital structures or historical cost basis. Adjusted EBITDA is also a non-GAAP financial measure that further excludes the impact from non-routine items. Management uses EBITDA and Adjusted EBITDA as alternative bases for comparing the operating performance of Eagle from period to period and for purposes of its budgeting and planning processes. Adjusted EBITDA may not be comparable to similarly titled measures of other companies because other companies may not calculate Adjusted EBITDA in the same manner. Neither EBITDA nor Adjusted EBITDA should be considered in isolation or as an alternative to net income, cash flow from operations or any other measure of financial performance or liquidity in accordance with GAAP. The following shows the calculation of EBITDA and Adjusted EBITDA and reconciles them to net earnings in accordance with GAAP for the quarters ended June 30, 2023 and 2022 and the trailing twelve months ended June 30, 2023 and March 31, 2023:

¹ Represents the impact of purchase accounting on inventory costs and related business development costs

² The increase in stock-based compensation is due to the retirement of two senior executives during the quarter

Attachment 7

Eagle Materials Inc.

Reconciliation of Net Debt to Adjusted EBITDA

(unaudited)

(dollars in thousands)

GAAP does not define “Net Debt” and it should not be considered as an alternative to cash flow or liquidity measures defined by GAAP. We define Net Debt as total debt minus cash and cash equivalents to indicate the amount of total debt that would remain if the Company applied the cash and cash equivalents held by it to the payment of outstanding debt. The Company also uses “Net Debt to Adjusted EBITDA,” which it defines as Net Debt divided by Adjusted EBITDA for the trailing twelve months, as a metric of its current leverage position. We present this metric for the convenience of the investment community and rating agencies who use such metrics in their analysis, and for investors who need to understand the metrics we use to assess performance and monitor our cash and liquidity positions.
