VERTIV COMMENTARY Add-backs are forecasted to decline from $125 mm in 2019 to $55 mm in 2020. The Company anticipates further declines in add-backs in 2021 as current operational initiatives and the Digital Project are completed. While operational initiatives could continue, the current forecast assumes Vertiv absorbs all related spending in its reported results after 2020 and so does not contemplate add-backs in 2021, except for those related to Stock Compensation. 38
