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 7

Management uses EBITDA and Adjusted EBITDA as alternative bases for Impairment Losses1 25 – – comparing the operating performance of Eagle from period to period and for purposes of its Paper Mill Expansion Costs2 5 – – budgeting and planning processes. Adjusted EBITDA may not be comparable to similarly titled Gain on Sale of Businesses – (52) – measures of other companies because other companies may not calculate Adjusted EBITDA 3 in the same manner. Neither EBITDA nor Business Development Costs 18 7 – Adjusted EBITDA should be considered in isolation or as an alternative to net income, cash Kosmos outage and purchase accounting4 7 4 – flow from operations or any other measure of – – 8 financial performance in accordance with GAAP.

Reconciliation of Net Debt to Adjusted EBITDA $ in millions, Fiscal Year Ending March 31 GAAP does not define “Net Debt” and it should FY 20 FY 21 FY 22 not be considered as an alternative to cash flow Total debt, excluding debt issuance costs $ 1,575 $ 1,015 $ 950 or liquidity measures defined by GAAP. We define Net Debt as total debt minus cash and Cash and cash equivalents 119 264 19 cash equivalents to indicate the amount of total debt that would remain if the Company applied Net Debt $ 1,456 $ 751 $ 931 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 Adjusted EBITDA from Continuing Operations $ 471 $ 571 $ 657 from Continuing Operations, as a metric of its current leverage position. We present this metric Net Debt to Adjusted EBITDA 3.1x 1.3x 1.4x 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. 23
