Item 2.02 Results of Operations and Financial Condition.
On May 8, 2026, Koppers Holdings Inc. (the “Company” or “we”) issued a press release announcing first quarter of 2026 results. A copy of the press release is included in this Current Report on Form 8-K as Exhibit 99.1 and is furnished herewith.
Item 2.05 Costs Associated with Exit or Disposal Activities.
On May 8, 2026, the Company announced that it has made a conditional decision to discontinue distillation and chemical manufacturing operations at its facility in Stickney, Illinois, subject to the satisfaction of any bargaining obligations that might exist with the union that represents certain employees at that facility.
The conditional decision, which is pending negotiations and consultation with the union, was driven by challenging market conditions over the past decade, including unit operating costs outpacing our ability to capture higher pricing, reduced raw material supply from North American steel manufacturers, and increased capital requirements and, if finalized, will affect approximately 85 employees. The Company anticipates winding down the remaining distillation and chemical production activities by December 31, 2026, pending discussions with the union. The Company is tentatively targeting fourth quarter 2026 for shifting production to its coal tar distillation facility located in Nyborg, Denmark. As part of this conditional decision, the Company is continuing to evaluate potentially appropriate uses for the Stickney facility following the end of production activities.
The Company expects this action to result in pre-tax charges to earnings of $227 million to $262 million through the end of 2029, approximately $170 million to $195 million of which constitutes non-cash charges and approximately $57 million to $67 million of which constitutes cash expenditures. Estimates of the total pre-tax amount for each major type of cost associated with the discontinuation plan are: (i) retention and severance costs of approximately $5 million (including both for salaried and union employees, and pending negotiations and consultation with the union), (ii) accelerated depreciation and asset write-down costs of approximately $170 million to $195 million, and (iii) plant cleaning, waste disposal and demolition costs of approximately $52 million to $62 million.
Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
We held our Annual Meeting of Shareholders on May 7, 2026 (the “Annual Meeting”). At the Annual Meeting, our shareholders approved the First Amendment (the “First Amendment”) to the Koppers Holdings Inc. Amended and Restated Employee Stock Purchase Plan (the “ESPP”).

The summary of the ESPP, as amended by the First Amendment, contained in the 2026 Proxy Statement is qualified in its entirety by reference to the full text of the ESPP, which is filed as Exhibit 10.2 to our Current Report on Form 8-K filed on May 7, 2021, and the First Amendment, which is filed as Exhibit 10.1 to this Current Report on Form 8-K.
