### GROUP ADJUSTED EBITDA AND MARGIN
($ in millions)

"Group Adjusted EBITDA" is defined solely for purposes of this Proxy as group operating profit (loss) from continuing operations before interest, income taxes, depreciation, depletion, and amortization, extraordinary adjustments to asset values (gains or losses), asset impairment charges, material restructuring/reorganization expenses, gains or losses on extraordinary dispositions, gains or losses from currency translation adjustments, acquisition or divestiture-related gains/losses or expenses (including transaction expenses and purchase price accounting adjustments), expenses to comply with COVID-related policies or regulations, the impact of changes in accounting rules, any changes to federal, state or local tax laws that impact the Company's tax liability, in each case as approved by the HR Committee, and any other adjustments the HR Committee deems appropriate. GAAP does not define Group Adjusted EBITDA and it should not be considered as alternatives to earnings measures defined by GAAP, including operating profit. We use Group Adjusted EBITDA as a metric for incentive-based compensation. “Group Adjusted EBITDA Margin” is defined as Group Adjusted EBITDA divided by Revenues for the Group.
