Segment Information 11 Enpro Agreements to Sell GGB and Exit Engineered Materials Segment Adjusted Segment EBITDA is total segment revenue reduced by operating expenses and other costs identifiable with the segment, excluding acquisition and divestiture expenses, restructuring and impairment expense, non-controlling interest compensation, amortization of the fair value adjustment to acquisition date inventory, and depreciation and amortization. Corporate expenses include general corporate administrative costs.
