Explanatory Note
This amended Current Report on Form 8-K (this “Amendment”) is being filed by Koppers Holdings Inc. (the “Company”) for the purpose of amending Item 2.05 of that certain Current Report on Form 8-K originally filed by the Company on November 8, 2024 (the “Original Form 8-K”) in connection with its workforce reduction program in the U.S. As noted in the Original Form 8-K, all of the specific cost reduction actions related to the workforce reduction program were not fully defined and the Company was unable at the time to make a good faith determination of the cost estimates, or ranges of cost estimates, associated with actions to be implemented in connection with the workforce reduction program. This Amendment is being filed to provide updates on the Company's additional cost estimates or ranges of cost estimates. Except as described below, all other information in the Original Form 8-K remains unchanged.
Item 2.05 Costs Associated with Exit or Disposal Activities.
The Company estimates pre-tax restructuring charges, employee severance charges and related benefit costs for actions associated with the workforce reduction program to be in the range of $4 million to $5 million, which the Company anticipates will result in future cash expenditures of approximately $1 million.
In accordance with paragraph (d) of Item 2.05, the Company will timely file additional amendment(s) to this Current Report on Form 8-K should any of the information previously disclosed need to be updated.
Safe Harbor Statement
