MOTLEY DAVID L 4

What Happened
David L. Motley, a director of Koppers Holdings Inc. (KOP), received an award on 2026-06-15 consisting of 20.663 dividend-equivalent rights (DERs) linked to restricted stock units (RSUs). The transaction is reported as an acquisition (derivative) at $0.00 per unit (reported value $0). This is an award/grant under the company’s director deferred compensation arrangements, not an open-market purchase or sale.

Key Details

• Transaction date: 2026-06-15; Form 4 filed: 2026-06-17 (filed two days after the transaction, which appears timely for a Form 4).
• Award: 20.663 DERs; reported acquisition price: $0.00 (derivative grant).
• Shares owned after transaction: Not disclosed in the filing.
• Footnotes:
  • F1: Each DER is the economic equivalent of one share of Koppers common stock and accrued with respect to additional RSUs credited relating to deferred compensation.
  • F2: Once released, the RSUs corresponding to these DERs will be paid according to the reporting person’s prior election under the Koppers Director Deferred Compensation Plan (either lump sum or annual installments beginning the May 31 following separation or a later elected date).
• No indication of a 10b5-1 plan, sale, tax withholding, or late filing flag in this report.

Context: These DERs are a form of deferred compensation that represent the economic equivalent of shares and will convert to RSUs/payments under the company’s director deferred compensation plan. This is a grant/award (not a purchase or sale) and therefore is a routine compensation event rather than a direct public-market trading signal.
