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 5.02 of that certain Current Report on Form 8-K originally filed by the Company on January 9, 2026 (the “Original Form 8-K”), in connection with Jimmi Sue Smith’s agreement with the Company to retire from her position as the Company’s Chief Financial Officer effective January 5, 2026, her provision of transition services to the Company and her separation from service with the Company on February 28, 2026 (the “Separation Date”). This Amendment is being filed to provide the material terms of a transition agreement between Ms. Smith and Koppers Inc., a wholly owned subsidiary of the Company (“KI” and together with the Company, “Koppers”), regarding her separation from service with Koppers. Except as described below, all other information in the Original Form 8-K remains unchanged.
Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
On March 9, 2026, KI and Ms. Smith entered into a transition agreement (the “Transition Agreement”), effective as of March 17, 2026, in connection with Ms. Smith’s: (i) provision of continued services as Koppers’ Treasurer from January 5, 2026 through the Separation Date (the “Interim Employment Period”); (ii) her separation from service with Koppers at the conclusion of the Interim Employment Period; and (iii) her agreeing to assist in the transition of her services from the Separation Date through February 28, 2027 (the “Transition Period”).
Pursuant to the Transition Agreement, in exchange for Ms. Smith’s general release and waiver of claims, her employment and services during the Interim Employment Period and her agreement to provide transition services during the Transition Period, KI has agreed, among other things, to pay Ms. Smith $440,000, payable over the Transition Period and to allow Ms. Smith to remain eligible for her earned and unpaid 2025 annual cash incentive, based on actual business performance, which will be payable in a lump sum on or around April 4, 2026, which is the same time such annual cash incentive is paid to other executives. In addition, in consideration and conditioned upon her services during the Transition Period, KI has agreed to pay Ms. Smith $123,400 in the form of a lump sum cash payment (representing the value of the equity awards that Ms. Smith would have become vested in during the Transition Period) and $330,000, payable in a lump sum on or around April 8, 2027 (representing her target 2026 annual cash incentive opportunity she would have been eligible for during the Transition Period if she continued to be a full-time employee).
The foregoing description of the Transition Agreement does not purport to be complete and is qualified in its entirety by reference to the complete text of the Transition Agreement, a copy of which will be filed as an exhibit to the Company’s next Form 10-Q, which will be incorporated by reference herein.
