EAGLE MATERIALS REPORTS SECOND QUARTER RESULTS

DALLAS, TX (October 29, 2024) Eagle Materials Inc. (NYSE: EXP) today reported financial results for the second quarter of fiscal 2025 ended September 30, 2024. Notable items for the quarter are highlighted below (unless otherwise noted, all comparisons are with the prior year’s fiscal second quarter):

Second Quarter Fiscal 2025 Highlights

Commenting on the second quarter results, Michael Haack, President and CEO, said, “Eagle’s portfolio of businesses continued to perform well despite ongoing adverse weather during the quarter, which affected sales volumes primarily in our Cement and Concrete and Aggregates businesses. We generated record revenue of $624 million and increased cashflow from operations by 35% to $233 million. We used our strong cashflow to continue advancing our long-term growth and value-creation strategies: during the quarter, we completed a bolt-on aggregates acquisition, returned $69 million of cash to shareholders through share repurchases and dividends, and strengthened our balance sheet, ending the quarter with debt of $1.1 billion and a net leverage ratio (net debt to Adjusted EBITDA) of 1.2x.” (Net debt is a non-GAAP financial measure calculated by subtracting cash and cash equivalents from debt as described in Attachment 6).

Mr. Haack continued, “We remain optimistic about our near-term and future opportunities and confident in our ability to execute on them. The current economic environment is constructive for our businesses. Employment is strong, recent inflation data should support a more accommodative monetary environment, spending from the Infrastructure Investment and Jobs Act (IIJA) is still in the beginning phases, and housing supply remains chronically short because of decade-long production deficits.”

“We believe our well-positioned balance sheet should give us substantial financial flexibility and support our capital allocation priorities and long-term growth, and our consistent, disciplined operational and strategic approach should position us to continue to perform well through economic cycles and drive superior value for our shareholders.”

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 $418.7 million, a 2% decrease. Heavy Materials operating earnings were down 9% to $114.9 million. Both declines resulted from lower sales volume, partially offset by higher sales prices as well as the effects of the Aggregates acquisition described below.

Cement revenue for the quarter, including Joint Venture and intersegment revenue, was down 2% to $352.8 million, and operating earnings were down 5% to $115.9 million. These declines reflect lower Cement sales volume and a $7 million increase in Cement maintenance costs, partially offset by higher Cement net sales prices. The average net sales price for the quarter was up 3% to $156.51 per ton, as a result of Cement price increases implemented earlier this calendar year. Cement sales volume decreased 5% to 2.0 million tons. Sales volume was affected by ongoing adverse weather during the quarter, particularly in Texas in July and in our eastern markets during September.

Concrete and Aggregates revenue decreased slightly to $65.9 million, reflecting lower Concrete and Aggregates sales volume, partially offset by higher Concrete and Aggregates pricing. The second quarter operating loss of $1.0 million reflects lower Concrete and Aggregates sales volume and approximately $0.7 million of expenses from the impact of the step-up in inventory values related to an Aggregates acquisition during the quarter. We acquired a small mine located near one of our existing mines in Kentucky. The acquisition was completed in August with a purchase price of $24.9 million.

Light Materials: Gypsum Wallboard and Paperboard

Revenue in the Light Materials sector, which includes Gypsum Wallboard and Paperboard, increased 5% to $244.1 million, reflecting higher Wallboard and Paperboard sales volume and sales prices. Gypsum Wallboard sales volume improved 3% to 752 million square feet (MMSF), while the average Gypsum Wallboard net sales price increased 1% to $236.88 per MSF.

Paperboard sales volume for the quarter was up 6% to 85,000 tons. The average Paperboard net sales price was $595.19 per ton, up 10%, consistent with the pricing provisions in our long-term sales agreements that factor in changes to input costs.

Operating earnings in the sector were $98.2 million, an increase of 5%, reflecting higher Wallboard sales volume and net sales prices.

Corporate General and Administrative Expenses

Corporate General and Administrative Expenses during the second quarter includes approximately $1.0 million of costs associated with business development and transaction diligence.

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 consolidated income statement. Refer to Attachment 3 for a reconciliation of these amounts.

Reconciliation of Non-GAAP Financial Measures

(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 the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting and business development costs and litigation losses (Non-routine Items). Management uses measures of earnings excluding the impact of Non-routine Items as a performance measure 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 September 30, 2024 and 2023:

Attachment 6, continued

EBITDA and Adjusted EBITDA

We present Earnings before Interest, Taxes, Depreciation and Amortization (EBITDA) and Adjusted EBITDA to provide additional measures of operating performance and allow for 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 and stock-based compensation. 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 September 30, 2024 and 2023, and the trailing twelve months ended September 30, 2024 and March 31, 2024:

Attachment 6, continued

Reconciliation of Net Debt to Adjusted EBITDA

GAAP does not define “Net Debt” and it should not be considered as an alternative to debt as 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 an alternative metric to assist it in understanding its 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.
