End-Use Applications US Building Code and Specification Driven Cement is the essential binding material in concrete which has • Unrivaled strength, durability, longevity and resilience • Energy efficiency • Doesn’t burn, rust or rot • Malleable at the jobsite • Few practical cement substitutes, and some substitutes have diminishing availability, e.g., fly ash • Provides comparable if not superior performance in terms of embodied carbon, resilience, safety, and climate adaptability when compared with other building materials Concrete is the most used building material in the world, and one that is critical for sustainable development US End-Use Cement Segments Wallboard Applications Applications Residential Construction ~30% ~80% and Repair and Remodeling Infrastructure, ~50% Roads and ~0% Bridges Non- ~20% Residential ~20% Construction The water molecule imbedded in gypsum wallboard chemistry provides an inherent fire resistance benefit that is essential in meeting US construction specifications There are few practical substitutes, and wallboard is not generally imported to the US from offshore

Adjusted EBITDA Reconciliation $ in millions, Fiscal Year Ending March 31 FY 21 FY 22 FY 23 Net Earnings, as reported $ 339 $ 374 $ 462 (Earnings) from Discontinued Operations (5) – –Income Tax Expense 90 101 127 Interest Expense 44 31 35 Depreciation, Depletion and Amortization 129 129 139 EBITDA from Continuing Operations $ 597 $ 635 $ 762 Gain on Sale of Businesses (52) – –Business Development Costs1 7 – –Purchase Accounting2 4 – 2 Loss on Early Retirement of Senior Notes – 8 –Stock-based Compensation3 15 14 17 Adjusted EBITDA from Continuing Operations $ 571 $ 657 $ 782 We present Earnings before Interest, Taxes, Depreciation and Amortization (EBITDA) from Continuing Operations and Adjusted EBITDA from Continuing Operations to provide more consistent comparison of operating performance from period to period. EBITDA from Continuing Operations 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 from Continuing Operations is also a non-GAAP financial measure that excludes the impact from non-routine items, such as purchase accounting (Non-routine Items) and stock-based compensation. Management uses EBITDA from Continuing Operations and Adjusted EBITDA from Continuing Operations 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 from Continuing Operations may not be comparable to similarly titled measures of other companies because other companies may not calculate Adjusted EBITDA from Continuing Operations in the same manner. Neither EBITDA from Continuing Operations nor Adjusted EBITDA from Continuing Operations should be considered in isolation or as an alternative to net income, cash flow from operations or any other measure of financial performance in accordance with GAAP. The table beside shows the calculation of EBITDA from Continuing Operations and Adjusted EBITDA from Continuing Operations and reconciles them to net earnings in accordance with GAAP for the fiscal years ended March 31, 2023, 2022 and 2021.    1 Represents non-routine expenses associated with acquisitions and other strategic transactions. 2 Represents the cost impact of the fair value markup of acquired inventory. 3 The increase in stock-based compensation is due to the retirement of two senior executives during the first quarter of fiscal 2023.

Net Debt to Adjusted EBITDA Reconciliation $ in millions, Fiscal Year Ending March 31 FY 21 FY 22 FY 23 Total debt, excluding debt issuance costs $ 1,015 $ 950 $ 1,100 Cash and cash equivalents 264 19 15 Net Debt $ 751 $ 931 $ 1,084 Adjusted EBITDA from Continuing Operations $ 571 $ 657 $ 782 Net Debt to Adjusted EBITDA from Continuing Operations 1.3x 1.4x 1.4x 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 from Continuing Operations,” which it defines as Net Debt divided by Adjusted EBITDA from Continuing Operations, 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.
