BALL M LEROY 4

What Happened

• LeRoy Ball, CEO and Director of Koppers Holdings (KOP), had performance share units (PSUs) and related dividend equivalent rights (DERs) vest on Feb 26, 2026. As a result he was issued 50,025 shares (award) and additional DER-related shares (1,215 reported). To satisfy tax withholding on the vesting, Ball surrendered 22,236 shares to the issuer at $37.24 per share, generating proceeds/withholding of $828,069. Several derivative-related entries reflect the conversion/release of DERs and PSU settlement; the awarded shares show $0 acquisition price because they were compensation awards.

Context

• These transactions are compensation-related (PSU vesting and DER releases), not an open-market purchase or indicative "buy" signal. Surrendering shares to cover taxes on vested awards is a routine administrative action and does not by itself indicate the insider’s view of the stock.
• For retail investors: awards increase insider-held shares but some were immediately surrendered for taxes; derivative entries mean rights tied to the PSUs were converted into shares upon vesting.
