DALLAS, TX (May 18, 2023) Eagle Materials Inc. (NYSE: EXP) today reported financial results for fiscal year 2023 and the fiscal fourth quarter ended March 31, 2023. Notable items for the fiscal year and quarter are highlighted below. (Unless otherwise noted, all comparisons are with the prior fiscal year or prior year’s fiscal fourth quarter, as applicable.)

Full Year Fiscal 2023 Highlights

Fourth Quarter Fiscal 2023 Highlights

Commenting on the annual results, Michael Haack, President and CEO, said, “We are pleased to announce another exceptional quarter and year at Eagle. We achieved record financial results and made strong progress on all strategic priorities. During the fiscal year, we expanded

gross margins by 190 bps to 29.8%, reported record earnings per share of $12.46, generated operating cash flow of $542 million, and repurchased 3.1 million shares of our common stock for $388 million. We also increased production of our eco-friendly Portland Limestone Cement product and integrated several acquisitions which should improve our already enviable low-cost producer position. At the end of the fiscal year, debt was $1.1 billion, and our net leverage ratio (net debt to Adjusted EBITDA) was 1.4x, giving us substantial financial flexibility for disciplined capital allocation.”

“Employee health, safety and environmental stewardship remain core objectives, and we demonstrated meaningful progress in all areas over the year. We released our updated Environmental and Social Disclosure report, which is available on our website. In fiscal 2023, our safety performance continued to outpace the industry average, and we achieved the lowest recordable injury rate in the company’s history. We also made significant progress in reducing our carbon footprint with the increased production and sale of our Portland Limestone Cement product, which has a lower carbon intensity than standard cement with similar performance attributes.”

Mr. Haack concluded, “Looking ahead, we anticipate continued attractive fundamentals in our markets, despite headwinds relating to higher interest rates and affordability constraints in single-family residential construction. Among the favorable demand factors we expect will affect our results in future periods are projected funding increases for infrastructure projects and healthy demand for heavy industrial projects and multi-family residential construction. We remain well-positioned to capitalize on these conditions given our geographical footprint across the US heartland and fast-growing Sunbelt and our financial strength and flexibility.”

Capital Allocation Priorities

Eagle remains dedicated to a disciplined capital allocation process to enhance shareholder value. Consistent with our track record, our allocation priorities remain unchanged, as follows: 1. investing in growth opportunities that meet our strict financial return standards and are consistent with our strategic focus; 2. operating capital investments to maintain and strengthen our low-cost producer positions; and 3. returning excess cash to shareholders, primarily through our share repurchase program.

In the past five fiscal years, we have invested nearly $858 million in acquisitions, $478 million in organic capital expenditures, and $1.7 billion in share repurchases and dividends.

Segment Financial Results

Heavy Materials: Cement, Concrete and Aggregates

Fiscal 2023 revenue in the Heavy Materials sector, which includes Cement, Concrete and Aggregates, as well as Joint Venture and intersegment Cement revenue, was $1.3 billion, an 11% increase. Heavy Materials annual operating earnings increased 7% to $297.0 million, primarily because of higher Cement net sales prices.

Fiscal 2023 Cement revenue, including Joint Venture and intersegment revenue, was up 7% to $1.1 billion, and Cement operating earnings increased 7% to $278.8 million. The annual revenue and earnings increases reflect higher net sales prices, the effect of which was partially offset by a decrease in the volume of cement sold.

Fourth quarter Cement revenue, including Joint Venture and intersegment revenue, was up 14% to $213.8 million. Operating earnings increased 59% to $45.3 million, reflecting higher net sales prices, partially offset by higher operating costs, namely energy.

Fiscal 2023 revenue from Concrete and Aggregates increased 35% to $239.5 million, reflecting higher sales prices and Concrete volume as well as the contribution of approximately $44.5 million from the acquired business in northern Colorado. Concrete and Aggregates reported fiscal 2023 operating earnings of $18.3 million, down 1%, reflecting higher operating costs primarily related to diesel fuel.

Fourth quarter Concrete and Aggregates revenue was $53.1 million, an increase of 43%, due to higher pricing and Concrete sales volume as well as the contribution of approximately $10 million from the acquired business in northern Colorado. Fourth quarter operating earnings were $2.6 million, a 74% increase, reflecting higher pricing and sales volume.

Light Materials: Gypsum Wallboard and Paperboard

Fiscal 2023 revenue in the Light Materials sector, which includes Gypsum Wallboard and Paperboard, increased 22% to $980.9 million, reflecting improved Wallboard sales volume and pricing.

Paperboard annual sales volume was down 2% to 326,000 tons.

Fourth quarter Light Materials revenue increased 11% to $244.2 million, reflecting higher Wallboard pricing and a small increase in Wallboard sales volume. Gypsum Wallboard sales volume increased 1% to 756 million square feet (MMSF), while the average Gypsum Wallboard net sales price increased 17% to $239.39 per MSF. Paperboard sales volume for the quarter was down 2% to 80,000 tons.

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 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 Consolidated Statement of Earnings. Refer to Attachment 3 for a reconciliation of these amounts.

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, such as purchase accounting on inventory costs and losses on early retirement of Senior Notes (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 calculations of EBITDA and Adjusted EBITDA and reconciles them to net earnings in accordance with GAAP for the quarters and fiscal years ended March 31, 2023 and 2022:

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.
